✅ The low beam headlights of the VAZ 2109 do not light

The headlights on the VAZ-2110 do not work. Fuses are intact

When the headlights on any car simply do not work, this is an ordinary case.
The cause could be the light switch, fuses, or other common things. The “ten” has a feature, without knowing which you can check everything you can to the point of stupor, but still not find the fault. Usually everything looks like this: the headlights or side lights of the “ten” do not work, and randomly, for example, the left side headlight does not work, the side lights on the right front and left rear do not work. The fuses are intact and many owners of the “ten” are very surprised. It's no wonder if you don't know one secret.

This secret is located in the fuse box, which on the VAZ-2110 even looks like a black box. Once you open it, you will see fuses and relays, with one relay being larger than all the others. It is called a lamp monitoring relay and ensures that the lamps in the headlights and side lights are intact. When a light bulb burns out in the indicated places, the relay sends a signal to the display unit of the on-board control system, the pictogram lights up in it and a typical decimal “ding-ding” is heard.

Inside this relay there are four spirals - these are resistors and the point is that one of these spirals can burn out. This happens, of course, for a reason, but as a result of a short circuit, but the main “trick” is that the resistors of this relay burn out faster than the fuses in the block! That is, absolutely all the fuses are intact, everything is great, but some light bulbs do not work. What is also confusing is that the failure occurs according to an illogical pattern (which may not work, described above), which is why many people think about a bad “ground” in some connection.

If you know about this feature of the “tens”, then identifying a burnt-out relay is a couple of trifles. It can be freely pulled out of the block and disassembled. To disassemble this relay, you need to carefully pry off the bottom cover with a screwdriver, from which the contacts come out, and remove it. Resistors will be visible immediately, and a burnt one even more so. Then it is better, of course, to buy a new relay, but it is not a fact that it will not burn out the first time you turn on the headlights - most likely there is a short circuit in the network.

Therefore, to diagnose a short circuit, it is better to make sure that the fuses are reliable.

, use a soldering iron to fuse a wire onto the burnt resistor to restore it and put the relay in place.
If the fuse does not blow, there is a chance that the relay has simply died due to, for example, old age. If the fuse also fails, you need to look for a short circuit
.

Circuit breakers

This is the second most common cause of low beam failure. If the left headlight does not light, then it is worth inspecting fuse F6.

Where is he located? It is located in a block hidden under the steering wheel. To get there, you need to remove the protective cover, which is held in place by three clips.

When the right light fixture does not function, look at fuse F7.

The protective devices mentioned above have the same rating - 7.5 amperes. The easiest way is to replace the damaged fuse with a working one. If one is not at hand, then as a temporary measure a “bug” is installed, that is, a jumper made of any suitable piece of copper or aluminum wire. In a pinch, even regular foil will do.

It is worth knowing that frequent blown fuses clearly indicate problems with the wiring. As a rule, a malfunction here often occurs due to the fact that the insulation of current-carrying elements is frayed. It is important to find the defective location and insulate it as soon as possible, since the occurrence of a short circuit leads to a fire in the vehicle.

As a rule, the cause of low beam malfunction on a VAZ 2110 is burnt out light bulbs. However, sometimes the lack of lighting is due to the failure of other components. Below we will look at how to replace lamps, as well as the most common reasons why the low beam does not light up and how to eliminate them.

How to find a short circuit

You will need a circuit breaker or a blown fuse, through one of your choice, connect the test lamp. Burning indicates a short circuit in the circuit.
Next, first turn off the socket, then the relay and switch. Where the lamp stops burning, a part of the circuit in which a short circuit has occurred has been found.

With the help of a car repair manual, it is easier to find components and identify wires.

Movement is prohibited unless the low and high beams are on. Those who have suffered such a fate should not fall into despair. The first step is to make a diagnosis, taking into account symptoms uncharacteristic of normal operation. This will significantly speed up troubleshooting. Sometimes, by resorting to simple strategies and using a basic set of tools, you can quickly fix the problem yourself, without resorting to the help of car service specialists. Thus, significantly saving time and money. If there is no knowledge and experience in such matters, nothing can be done. It is better to seek qualified help. The car is a source of increased danger; in order to avoid unpleasant situations, it is necessary to carefully monitor its technical condition. Good luck to everyone on the roads, no nails, no rods.

Replacing lamps

The process of replacing lamps on a VAZ 2110 is extremely simple. However, before you begin this operation, you must purchase new lighting elements.

This vehicle is factory equipped with H7 standard halogen bulbs. Today there is a large selection of lamps on sale, not only halogen, but also other types - xenon and LED.

Their features, advantages and disadvantages have been discussed many times on car enthusiast forums, so below we provide only a comparative table with the main characteristics of these lamps:

Note! The most optimal color temperature of the light flux is in the range of 4300 – 5000 K.

It must be said that in addition to the data from the table, when choosing, you should also take into account the penetrating ability of the light flux. Halogen lamps are the leaders in this parameter - they illuminate the road much better in rain, fog or snow.

In addition, installing xenon or LEDs in the fog lights of the VAZ 2110 will require electrical intervention, in particular the installation of additional equipment (ignition units). Therefore, it will not be possible to perform their high-quality and safe installation with your own hands.

Note! Experts recommend changing light bulbs in pairs so that both headlights shine equally. In addition, their service life is approximately the same, so if one of them burns out, the second one will soon fail.

Each car owner must choose for himself which light for the VAZ 2110 will be better based on his own financial capabilities, weather conditions of the car, etc.

How to replace the lamp

Instructions for replacing light bulbs look like this:

First of all, you need to open the hood and disconnect the terminal from the battery.
Then you need to remove the plug located closer to the wing.
Next, you need to unfasten the spring clip, which presses the light bulb to the headlight housing.

After this, you should carefully disconnect the block from the contacts and remove the light bulb itself, since nothing else interferes with it.
Now you need to insert new light bulbs in the same position in which the old ones were located, connect the block to the contacts and secure everything with a bracket.
At the end of the work, you should install the plug in place.

Note! When replacing lamps, it is important not to touch the glass with your fingers. Otherwise, grease stains will remain on the surface, which will lead to overheating and failure of the lighting element.

The lamp replacement is now complete. As a rule, this operation takes several minutes even for beginners.

Advice! Many car owners are interested in how to improve headlights? The easiest way is to disassemble the headlights, wash them, replace the glass if necessary and adjust the light beams. As a rule, these simple procedures give good results.

Replacing fuses

If after replacing the bulbs the lighting still does not work, you should check the fuses. The mounting block is located on the left side of the steering wheel.

Fuse F2 is responsible for low beam lighting in the left headlight unit, and F12 in the right one. It must be said that a fuse malfunction cannot always be detected visually. Therefore, it is better to install new fuses.

If the fuses are intact, but the lighting still does not turn on, you need to find the cause of the malfunction. To do this, you will need a test lamp, or even better, a multimeter.

It must be said that repairing the low beam on a VAZ 2110 is not difficult - you just need to ring the circuit and find a break in order to fix it.

Below is the optimal procedure:

Since the low beam relay on the VAZ 2110 is often the cause of a low beam malfunction, you can start checking with it. Using the device, you need to determine whether voltage is supplied to it and whether it is at the output. If there is no voltage at the output, then the relay needs to be replaced.
If there is no voltage supplied to the relay and there is no voltage at the fuse terminals, then you should check the VAZ wiring from the switch to the fuses, as well as the switch itself.
If there is voltage at the output of the relay, you need to check whether it is supplied to the lamp connector. Often the cause of the malfunction is burnt or oxidized contacts. If the low and high beams disappear at once, then the ground wire in the headlight may have come loose.

Note! The cause of relay malfunction is often oxidized contacts, which simply need to be cleaned.

Thus, by checking all the main components along the circuit, you will definitely find the cause of the malfunction. The low beam diagram for the VAZ 2110, which is shown above, will help to simplify this work.

High or low beam does not turn on

The inability to turn on two high beam headlights requires a mandatory check of relay K5. It is located in the mounting block located in the cabin (to the left of the steering wheel).

How to find out if this relay is working. Pull it out and place a jumper between the 87 and 30 connectors of the block. After this, try to turn on the light. The activation of the headlights indicates a breakdown of the above-mentioned unit. It cannot be repaired in principle, so it will have to be replaced.

The reason for the failure of both low beam lamps is diagnosed in the same way, only you will have to close contacts 87 and 30 on the K4 relay block - it is the relay that is responsible for this electrical circuit.

Adjustment

Once a year, the low beam on the VAZ 2110 should be adjusted. This procedure is necessary in order to increase the lighting efficiency and also to prevent dazzling oncoming drivers.

Below we will take a closer look at how to adjust the low beam headlights:

You need to find a flat area with a wall that will serve as a screen.
The car should be placed at a distance of five meters from the screen. A passenger must sit in front. You can also put a load weighing 75 kilograms in the car.
On the screen you need to draw a horizontal line at 600 mm, as well as a second line 75 mm below the first.
Then you need to draw three vertical lines - the two outer lines should correspond to the centers of the headlights, and the middle one should be located in the middle between them.
The headlight hydraulic adjustment handle should be moved to the position corresponding to the minimum load.
One of the headlights must be covered with cardboard or a sheet of plywood.

Why the low and high beams on the VAZ 2110 do not work

To figure out why the low and high beam headlights on a VAZ-2110 car do not work, you need to know what you need to pay attention to when trying to fix this problem. These cars are equipped with a headlight unit where the direction indicators are located, as well as two options for high and low beam headlights. two single-filament lamps in the headlight unit (separately for the low beam headlights and separately for the high beam), and in the other case there is one , two-filament lamp . Therefore, there are two plugs in the electrical wiring for connecting the corresponding set of headlights.

Also involved in the operation of the electrical circuit of external lighting are: external lighting switch , which is located in the cabin on the front panel ; The headlight switch is located on the steering column; The low beam relay, the high beam relay and 4 fuses are located in the mounting block, and the high beam warning lamp is located on the instrument panel. When the high beams are turned on, all 4 filaments in the exterior lighting lamps should light up.

If one or more threads of the headlight lamps do not light, then, without getting out of the car, check the integrity of the fuses located in the mounting block under numbers F2, F3, F12, F13. Fuse F2 protects the low beam filament in the left headlight, F3 protects the high beam filament in the left headlight, F12 protects the low beam filament in the right headlight, F13 protects the high beam filament in the right headlight and the high beam indicator lamp.

Provided that the fuses are intact and their contacts are not oxidized , you will have to get out of the car, open the hood and check the serviceability of the corresponding lamps, those that do not light up. It's not difficult to do this. You just need to remove the rear casing, disconnect the wire block, remove the spring securing the light bulb in the headlight and pull out the light bulb holder by turning it counterclockwise. We replace the burnt-out lamp with a similar new one.

If the fuses and lamps are intact and undamaged, then we check the two relays indicated on the electrical diagram as K4 and K5. Their possible malfunctions will be oxidation or burning of contacts , which can be eliminated by cleaning them. If the relays fail completely, you will have to install serviceable ones instead.

After making sure that all of the above devices are in working order, you will have to check the reliability of the connection in the blocks included in the electrical circuit of the headlights and the fastening of the headlights' mass wires. One ground fastener is located on the left, next to the battery on the air intake mount. Second from the right, in the place where the adsorber is located. If this does not help, you will have to remove the headlight switch and the exterior lighting switch one by one and check the condition of the contacts in them.

In addition to malfunctions associated with the electrical circuit of the headlight, fogging of the lens attached to the headlight housing is also possible. This usually occurs as a result of water getting inside the headlight either due to careless engine washing, or during rain due to a leaky lens fastening glass. Well, knowing about these possible malfunctions, the driver can deal with them independently.

Possible causes of failure

A car is a complex mechanism. Both used and new cars are not insured against failure of one or another part. When faced with an unexpected situation on the road, the main thing is not to panic, but to try to figure out what’s wrong and fix the problem.

List of common causes based on symptom diagnosis:

the lamp or fuse has blown;
the cartridge has failed;
short circuit;
problems in the charging system.

First of all, we check the fuse and lamps. If the problem is not with them, we move on, testing the light control module for performance. Sometimes, replacing a spare part does not give positive results. And all because the reason is the melting of the connecting chip. These actions help if the low and high beam headlights on the Kalina do not light up. Before buying a new LCM (light control module), you can carefully remove it and check whether the connections have oxidized. It happens that the wiring seems to be touching the board, but the current did not conduct, which was the cause of the breakdown. Then you should use a soldering iron to go over all the contacts. Put the board back and reassemble everything.

A common “disease” of the Lada “Kalina” associated with the cessation of light operation is halogen lamps. They burn out due to dust getting into the headlight, the lamp overheats and fails.
The second reason is increased voltage in the car’s on-board network. Using a tester, it is easy to find out what voltage the generator produces. When the engine is running, it should not exceed 14.4 volts. At higher rates, it may be necessary to replace the regulator relay.

Why doesn't the low beam headlight light up? Troubleshooting

Many car owners are faced with a situation where the low beams are not on. In this case, the distant one turns on normally, and its serviceability is beyond doubt. According to statistics, every third driver is familiar with such a breakdown firsthand. In this case, the first thought that appears in the head is the failure of the optics itself. In reality, the reason may be completely different.

The defect is well known to owners of VAZ cars, who sometimes encounter the problem even after purchasing a new vehicle. In this case, most often the headlight on the right side of the car does not light up. In turn, the head light source on the left suffers from a similar problem to a lesser extent.

But it would be dishonest to say that the breakdown is typical only for domestic cars. Foreign cars of various manufacturers are also susceptible to this “disease”. The difference is that each part has its own safety margin and resource.

What to do if the low beam does not light up? The car owner has two solutions - contact qualified specialists to fix the problem, or do the work yourself. When choosing the second option, you must have the necessary tools and knowledge of the car’s design, as well as the features of the electrical circuit. If the high beam lights up normally, but there are problems with the low beam, there may be several reasons:

The light bulb has failed.
Problems with wires (break, short circuit).
The fuse that powers the low beam lamp has blown.
Other reasons.

Regardless of the problem, you can easily fix it yourself. At the same time, knowing the reasons why the headlight does not light is useful for every car owner. There are situations in life when a fault occurs on the road, and the service station is several tens of kilometers away.

Technically difficult stages

More difficulties will arise at the next stage. If the luminous flux is lost due to a short circuit, you will need to remove the glass from the headlight. It is fixed using a fairly dense sealant, so you will need an installation cutter. A standard industrial hair dryer will not work here. Prolonged thermal exposure will destroy the structure of the lighting element.

Use a cutter to carefully pry off the surface of the glass and slowly cut the sealant. After this, both parts are separated. The work is completed by replacing the failed element and restoring the integrity of the headlights.

To check, you need to turn on the lighting device, making sure that it is working correctly. If for some reason the high or low beam does not turn on, you need to make sure the wires are connected correctly.

Correctly setting the headlights is the key to the safety of the driver and other road users. The slightest failure will significantly impair road visibility at night. In many ways, this contributes to an increase in the number of possible accidents.

one side Oddly enough, the situation when the high beam on the headlights turns on, but the low beam does not, arises quite often. According to statistics, every third driver has to deal with such a situation. At the same time, straightforward logical conclusions that the lack of light is caused by failure of the optics do not always work here.

There are a large number of cases known, for example, when on cars produced by VAZ, even if they are practically new, such a defect most often occurred on the headlights located on the right side of the car, while the left had some kind of immunity against this problem. However, one should not make hasty conclusions that this problem is the prerogative of exclusively domestic cars, since it also occurs on foreign cars.

And here you no longer have to blame the quality and reliability of the parts belonging to this or that brand - it’s just that sooner or later all the parts get tired or they simply exhaust their service life. If one low-beam headlight does not light, it is best to contact an experienced auto electrician at a car service center, but this type of problem can be fixed almost easily on your own. Of course, if you have a little free time and basic knowledge about the operation of electrical circuits.

A situation where it is not possible to turn on the low beam when the high beam is on can arise for several reasons:

the light bulb burns out;
fuse burned out;
there were problems with the wires;
non-standard reasons.

And almost all of them can be eliminated quite easily.

Knowing why such a malfunction can occur and how it can be eliminated is useful for every driver, because this can also happen during a long trip, when there are no service stations nearby. Let's try to deal with this problem in all possible ways.

Lamp burned out

If the low beam does not light up, the first thing the car owner will assume is that the filament is damaged. This is possible, because structurally the car headlight contains two spirals, each of which performs its own task. If one thread burns out, the second one continues to work normally. This is a feature of halogen lamps that provides additional reliability and safety.

To replace the lamp, proceed as follows:

Open the luggage compartment of the car.
Remove the protective housing from both sides of the headlight.
Discard the power wires.
Remove the spring fasteners.
Remove the burnt out light bulb and install a new one.
Return all previously dismantled components using the reverse algorithm.

When performing work, consider a number of rules:

Wipe the flask before installation using a soft rag soaked in alcohol. If you place a light bulb with greasy or dirty fingerprints on the surface, the product will quickly burn out.
Do not touch the flask with your hands (even if they are clean). Otherwise, marks remain on the lamp, reducing the life of the product. To avoid problems, it is recommended to wear cotton gloves. As a last resort, place the light bulb holding it through a clean rag or napkin.

Fuse blown

In a situation where the headlight does not light, you should make sure that the fuse through which the circuit of interest is powered is working. If it burns out, the low beam may also not work. To resolve the problem, do the following:

Open the block where all the fuses that supply various parts of the on-board network are located.
Find the required fusible insert. To do this, use the diagram of your car. Most often, a blown fuse can be detected visually.
Install a serviceable melting insert in place of the failed part.

If a blown fuse is a frequent problem, replacing it alone will not solve the problem. The cause of the malfunction is most likely in the power wiring. To determine the location of the damage, use a multimeter, with which you need to ring the main parts and accurately diagnose the location of the damage. If you cannot determine the malfunction, contact a specialist at a service station. There is no point in delaying the problem for two reasons:

If the low beams are not on, the likelihood of an accident increases when driving in the dark.
A short circuit in the circuit can cause a fire in the wiring.

Problems with power cables

If the cause of the malfunction lies in the wires, check the entire chain through which voltage is supplied to the fuse box, relay and directly to the vehicle's head light source. The reason that the headlight does not light may be oxidation or weakening of the contact group on one of the pads. As a result, the current increases in problem areas of the circuit, and this leads to overheating. To restore normal contact, stretch the wire fastenings to the blocks, having previously processed the contact connections, using a needle file or sandpaper.

Electrical wiring

Electrical wiring is designed to supply electrical current to the consumer, in this case the high beam lamps. Problems with electrical wiring, partial lack of insulation, overheating of the wiring due to incorrectly installed fuses can cause a fire in the car, and you need to monitor the serviceability of the wiring as carefully as other mechanisms and devices of the car.

Important! A non-functioning high beam in conditions of insufficient visibility does not allow the driver to drive a car safely, and if problems arise with the high beam headlights on a VAZ car, knowledge of repair and diagnostics will help to quickly and effectively eliminate the problems that have arisen.

Lighting malfunctions often take car owners by surprise and force them to recall all their existing knowledge about the electrical part. So, if the high beams do not light up, you have to urgently take action, because such a malfunction can lead to a number of problems when driving at night, including an accident.

Causes of malfunction

To figure out why the high beams are not on, and subsequently fix the problem, it is important to know all the possible causes of the breakdown. Some of them can be fixed with your own hands, but in some cases, the help of specialists is required.

There are several reasons why the high beams do not light up:

The control relay has failed. Such a malfunction requires the involvement of service station specialists. It is unlikely that you will be able to change the relay yourself without the necessary knowledge.
The fuse has blown. If problems are detected with the head light, it is worth starting the diagnosis with the serviceability of the fuse insert. If it is damaged, replace the fuse. To avoid problems, it is worth having several sealed parts of different denominations in the glove compartment or trunk.
The light bulb has burned out. In modern cars, various lamps are installed, the cost and quality of which differ. There are quite expensive lamps, and not every car owner will decide to buy them. Regardless of the price, it's worth keeping at least one spare bulb in your car. Such foresight can save you if the high beams are not on, and you urgently need to go somewhere at night.

If there is no spare bulb, do at least minimal manipulations. So, if the light source in the left headlight is damaged, it is worth replacing the bulb from the right headlight. This is done in order to indicate the dimensions of the car on the highway and increase the safety of movement.

The low and high beam switch is broken. If you have experience and knowledge in repairing the electrical part of a car, you can try to fix the problem yourself. If you lack the skills, you should contact a service station.

Video: The high beam on a VAZ 2110 is blinking, the switch is broken

If the high beams do not light up, you cannot ignore the problem with the car’s on-board network. There are many options - oxidation of contact connections, deterioration of conductivity and even a short circuit in the network. The presence of a short circuit is indicated by a blown fuse (especially if it occurs repeatedly).

It is worth considering that repairing wiring yourself is a labor-intensive task. The problem is that if there is a short circuit, nearby wires may also be damaged, which will only worsen the problem. To be sure of the quality and speed of repairs, you should contact a specialist who specializes in car electrics.

How to find and fix the problem

If you have determined why the high beams are not on, you can begin troubleshooting. Let's consider the main recommendations in relation to possible breakdowns:

LIGHT BULBS. In practice, this reason is considered the most common. To assess the integrity of some types of lamps, there is no need to dismantle them - it is enough to perform a visual check. In extreme cases, special devices can be used. If the diagnostics show a faulty lamp, it should be replaced. When performing work, it is forbidden to touch the glass part of the lamp with your fingers, as this will reduce the service life of the device.
High beam RELAY. When determining the reason why the high beams are not on, car owners often find that the relay through which power is supplied to the headlight is faulty. In the absence of knowledge and experience, it is better not to touch anything. If there is a certain base, it is worth studying the instructions, and then proceeding with the repair.

If the video does not show, refresh the page or

CIRCUIT BREAKERS. This malfunction can be determined by visual inspection or using a multimeter. If a blown fuse is detected, it must be replaced. When choosing a replacement part, it is worth taking into account the rated current of the circuit. It is not recommended to install a fusible link with an overrated rating. This may cause more serious damage to the circuit or even a fire.

If, after installing a new fuse, the high beams do not light up again, and the same problem (burnout) is detected, then the cause must be looked for in the wiring.

Steering column control unit. Here the recommendations are similar to those for the high beam relay. If you have no experience, it is better not to take on this job.

If the high beams do not light up, it is worth checking the quality of the wire connections in numerous terminals. But this recommendation is typical only for older car models. In modern machines, all connections are highly reliable, so it is useless to look for the reason here.

The low beam of the VAZ 2110 does not light up

If the relays completely fail, you will have to install serviceable ones instead. After making sure that all of the above devices are in working order, you will have to check the reliability of the connections in the blocks included in the electrical circuit of the headlights and the fastening of the headlights' ground wires. One ground fastener is located on the left, next to the battery on the air intake mount. Second from the right, in the place where the adsorber is located. If this does not help, you will have to remove the headlight switch and the exterior lighting switch one by one and check the condition of the contacts in them.

In addition to malfunctions associated with the electrical circuit of the headlight, the lens attached to the headlight housing may also fog up. This usually occurs as a result of water getting inside the headlight either due to careless engine washing, or during rain due to a leaky lens fastening glass. Well, knowing about these possible malfunctions, the driver can deal with them independently. .

Usually everything looks like this: the headlights or side lights of the “ten” do not work, and randomly, for example, the left side headlight does not work, the side lights on the right front and left rear do not work. The fuses are intact and many owners of the “ten” are very surprised. It's no wonder if you don't know one secret.

If you know about this feature of the “tens”, then identifying a burnt-out relay is a couple of trifles. It can be freely pulled out of the block and disassembled. To disassemble this relay, you need to carefully pry off the bottom cover with a screwdriver, from which the contacts come out, and remove it. Resistors will be visible immediately, and a burnt one even more so. Then it is better, of course, to buy a new relay, but it is not a fact that it will not burn out the first time you turn on the headlights - most likely there is a short circuit in the network.

Therefore, to diagnose a short circuit, it is better to make sure that the fuses are reliable, use a soldering iron to fuse a wire onto the burnt resistor to restore it, and put the relay in place. If the fuse does not blow, there is a chance that the relay has simply died due to, for example, old age. If the fuse also fails, you need to look for a short circuit.

Doesn't turn on

When a problem occurs and the low beam on a VAZ 2109 does not work, a lot can happen, but we will consider only the main options that most often lead to such consequences. We will immediately give recommendations on how to eliminate them:

The light bulb fuse has blown. Check the appropriate fuses, correct or replace them. The lamp filaments have burned out. The low beam lamp on the VAZ 2109 is being replaced, which corresponds to the manufacturer's instructions. The relay or switch contacts have oxidized. Use sandpaper or a knife to clean the contacts. The wires are damaged, their tips are loose, connections have become unusable. Carefully check the machine wiring for breaks, replace damaged areas with new wires and clean the contacts. Contact jumpers have oxidized at the site where the relay is installed that controls the operation of the lamps. Remove new electricity consumers from the system.

Tip: Use only standard bulbs so as not to overload the vehicle's on-board electrical system.

Repair

One of the basic rules associated with eliminating defects in a car is that you should not rush to buy new spare parts, since the old ones may still serve well. In this case, there is no need to rush to buy or install a new lamp, the price of which is quite high today. We recommend that you first check the serviceability of the old one; perhaps there is another reason for its inoperability. Therefore, before changing, check why the low beam on the VAZ 21099 is not on:
set your vehicle to the handbrake, first (reverse) gear, or place a shoe under the wheel;
open the hood;
remove the lamp from the headlamp that you think is burnt out and check its serviceability visually (by inspecting the spiral) and applying voltage from the battery - “-” to the side, “+” to the base (if it is working, it will light up). The faulty lamp should be replaced.

Advice: if you notice that the low beam on a VAZ 21099 is constantly on, replace the corresponding relay.

When you find a blown fuse, you should wonder what's wrong with your on-board electrical system because they don't just blow. This is a sign that a current has passed through it with a force greater than permitted. Most likely, there is a “short circuit” somewhere in the system that needs to be detected and corrected. After this, replace the blown fuse with a standard one.

Replacing lamps

The process of replacing lamps on a VAZ 2110 is extremely simple. However, before you begin this operation, you must purchase new lighting elements.

This vehicle is factory equipped with H7 standard halogen bulbs. Today there is a large selection of lamps on sale, not only halogen, but also other types - xenon and LED.

Their features, advantages and disadvantages have been discussed many times on car enthusiast forums, so below we provide only a comparative table with the main characteristics of these lamps:

Note! The most optimal color temperature of the light flux is in the range of 4300 – 5000 K.

Each car owner must choose for himself which light for the VAZ 2110 will be better based on his own financial capabilities, weather conditions of the car, etc.

How to replace the lamp

Instructions for replacing light bulbs look like this:

First of all, you need to open the hood and disconnect the terminal from the battery.
Then you need to remove the plug located closer to the wing.
Next, you need to unfasten the spring clip, which presses the light bulb to the headlight housing.

Replacing fuses

If after replacing the bulbs the lighting still does not work, you should check the fuses. The mounting block is located on the left side of the steering wheel.

If the fuses are intact, but the lighting still does not turn on, you need to find the cause of the malfunction. To do this, you will need a test lamp, or even better, a multimeter.

It must be said that repairing the low beam on a VAZ 2110 is not difficult - you just need to ring the circuit and find a break in order to fix it.

Below is the optimal procedure:

Since the low beam relay on the VAZ 2110 is often the cause of a low beam malfunction, you can start checking with it. Using the device, you need to determine whether voltage is supplied to it and whether it is at the output. If there is no voltage at the output, then the relay needs to be replaced.
If there is no voltage supplied to the relay and there is no voltage at the fuse terminals, then you should check the VAZ wiring from the switch to the fuses, as well as the switch itself.
If there is voltage at the output of the relay, you need to check whether it is supplied to the lamp connector. Often the cause of the malfunction is burnt or oxidized contacts. If the low and high beams disappear at once, then the ground wire in the headlight may have come loose.

Note! The cause of relay malfunction is often oxidized contacts, which simply need to be cleaned.

The fuse box in Priora is located at the bottom of the dashboard, on the left side of the steering wheel. To get to it, you need to open the cover, which is held on by three latches. Rotate each locking knob 90 degrees and pull the lid down and it will snap open.

F1 (25 A) - radiator cooling fan . If your fan does not work, check its motor by applying 12 V directly to it from the battery. If the engine is working properly, then most likely the problem is in the wiring or connectors. Check the serviceability of relay K1.

Adjustment

Once a year, the low beam on the VAZ 2110 should be adjusted. This procedure is necessary in order to increase the lighting efficiency and also to prevent dazzling oncoming drivers.

Below we will take a closer look at how to adjust the low beam headlights:

You need to find a flat area with a wall that will serve as a screen.
The car should be placed at a distance of five meters from the screen. A passenger must sit in front. You can also put a load weighing 75 kilograms in the car.
On the screen you need to draw a horizontal line at 600 mm, as well as a second line 75 mm below the first.
Then you need to draw three vertical lines - the two outer lines should correspond to the centers of the headlights, and the middle one should be located in the middle between them.
The headlight hydraulic adjustment handle should be moved to the position corresponding to the minimum load.
One of the headlights must be covered with cardboard or a sheet of plywood.

Then the light beam is adjusted according to the diagram. Adjustment is carried out with screws with plastic heads, which are located on the back side of the headlights. They rotate the optical element around the horizontal and vertical axis.
Next, you need to adjust the second headlight in the same way.

Here, in fact, is all the information on how to adjust the low beam headlights.

The low beam headlights on a VAZ 2110 may stop shining for various reasons, however, in any case, the fault can always be found and fixed by yourself. At the same time, we should not forget about adjusting the direction of the light beams, on which the effectiveness of the head lighting largely depends.

Car : VAZ-2112. Asks : Vasily Polunkin. The essence of the question : the low beam on the VAZ-2112 has stopped working, what should I do?

Good afternoon. I literally just got out of the car and saw darkness. The left low beam light does not light up. On the right it’s burning, but I had some kind of cloudiness there, it’s hard to see. I swapped them, left to right, the right one shines, the left one doesn’t.

Then I wonder why the left headlight does not light up. The far one on the left works, but the near one does not. What to do?

Is your neighbor not on fire? Let's fix it!

If nothing happens when you turn on the low beam. Nothing, even the indicator on the instrument panel does not light up, which means the power button is faulty.

Fuse

In most cases, if any electrical circuit on a car stops working, the fuse is to blame. Most likely there was a power surge and the fuse was blown.

Location of the fuse for the left and right low beam lamps

F2 - 7.5A - Left headlight (low beam)
F12 - 7.5A - Right headlight (low beam)

Let's go further along the chain. You need to find out if there is voltage at the headlight unit. To do this, you need to measure the voltage at the lamp plug.

If there is voltage, but the lamp does not light, then:

the lamp burned out,
The chip melted or for other reasons lost its functionality.

If there is no voltage, then you need to look for where the break is!

If all else fails

If none of the above helped you, then most likely there is a break in the circuit somewhere. It could appear as a result of:

mechanical impact (mice, rodents);
time (the wiring has deteriorated);
overheating of the wire and damage to its insulation.

This is a job for a professional electrician. The algorithm of actions is as follows.

We look at the voltage on the fuses. There should be 12 volts constantly.
We look at the voltage on one of the 33 contact chips. We need one with gray-black and gray wires in the corner part. These are the wires for the low beam headlights.
We look at the voltage at the headlight terminals.

If there is voltage everywhere, then the problem is an open circuit between the mounting block and the headlight.

When you turn on the car, the DRLs come on and two lights come on. When the headlights are turned on, the right DRL lamp does not light up, and also when the daytime running lights are turned on, all the lamps are on, but the right one is not.

The fuses are fine. Also, in the parking mode, the right brake light does not light up, although when the brake is pressed, it lights up. What could be the problem?

Change the light bulbs. The lamps have two filaments - P21/4W and W21/5W.

So, flies separately, cutlets in the other direction! DRLs are DRLs, dimensions are dimensions. DRL - thick filament in the lamp, 21 watts, size - thin, 5 watts. In this case, the lamp burned out. And it’s not a fact that the new one is good, the lamps themselves burn out once a month, then one, then another.
