Replacing the heater motor on a VAZ 2114 - how to remove/install the heater motor

The most frequently used component in any vehicle during cold weather is the heater. Without this device, driving a car will be less comfortable, so before the start of winter, the car owner is simply obliged to diagnose the health of the heater. If the system does not work, it can be caused by various problems, but the motor is usually the cause. In this article we will talk about how to replace the heater motor in a Nissan Qashqai or any other model.

Stove malfunctions

If the heater fan does not work in a Nissan Tiida, Qashqai, Beetle or any other car, then this problem needs to be solved as quickly as possible. After all, constant inoperability can lead to the fact that if the windows fog up, which happens quite often in winter, they will remain fogged up. Moreover, if it is frosty outside, the windows may also freeze, and the air temperature in the cabin will be generally low. We suggest you understand the main symptoms and causes of stove malfunctions.

Electric motor of the heater system of a Nissan car

Signs and causes

The three main symptoms of heater failure are:

• the system does not work, does not heat the air;
• The speed of the heater fan does not change, despite the adjustment;
• during operation, the heating system began to make sounds that were uncharacteristic of its operation, we are talking about creaks, whistles, squeals, etc.

If the motor only works at 4th speed, then the rotation speed resistor has burned out. As a rule, it is located next to the motor.

As practice shows, the main causes of such symptoms are as follows:

1. If the heater does not work at all, this may be due to wear of brushes or lamellas, as well as burnout of the winding. In this case, you will need to replace the system's electric motor. If the problem lies in a burnt-out transistor, then it will also need to be replaced. In some cases, the reason lies in a failed thermal fuse, which is located in the resistor block, then you only have to change this element.
2. If the fan does not change the rotation speed when adjusting this parameter from the passenger compartment, then most likely the problem lies in the transistor; this component will need to be replaced.
3. The appearance of extraneous sounds, as a rule, indicates wear of the bushing. If this is the case, then you will need to change the heater motor. You can read reviews online about replacing bushings with bearings - we do not recommend doing this, since the replacement procedure as a whole is a painstaking task, and it is not a fact that the result will suit you (the author of the video is the channel Valery Deryugin).

How to remove the heater motor of a VAZ 2114

The main thing for passengers is that the car is warm and comfortable. These conditions can be created by the stove provided in the car mechanism. It will not allow passengers to freeze even in severe cold. The operating principle of the heating system in the VAZ is identical. The car and the interior of her car are heated using a stove. The stove operates with the help of a fan, which is located in the interior of the cabin. The fan is capable of operating in three-speed mode.

EQUIPMENT OPERATION MECHANISM

The fan regulates the flow of air that will circulate inside the car.
It has several damper positions, which can be directed towards heating the feet, glass or the passenger part of the cabin. If the system does not work properly and is noisy, the heating process of the VAZ 2114 is reduced to zero. Warm air does not enter the cabin, as a result of which the car remains cold. This problem is especially noticeable in the cold season. In order to understand the reasons, you need to know how the operating mechanism of the heating system works:

1. 1. To supply heat to the interior of the car, it is necessary to adjust the supply of thermal air by closing and opening the tap.
2. 2. Through these actions, coolant enters the radiator, which contributes to the formation of heat. The stove operates at the maximum coolant level with a fully heated motor, which is about one hundred degrees.
3. 3. When the stove switches to different speed modes, the fan speed is regulated.
4. 4. In the car interior there are special partitions with the help of which you can determine the main root causes of failure of the VAZ 2114 stove.

In case of malfunctions, the cause should be sought in the following:

• The fuse has failed;

The most pressing reason. A faulty fuse does not work properly, which can be the main reason for the breakdown of the entire heating system of the vehicle. Often the cause of a blown fuse is a short circuit. To determine this deficiency, you will have to fully understand the operation of the safety chain.

• Poor contact in the inside of the mounting block;

Poor contact of the mounting block

The main cause of this malfunction is considered to be oxidized wiring. There is a solution to the problem: just reconsider the wires connected in front of the mounting block and replacement may be required.

• The ignition relay has failed;

Occurs as a result of a stuck ignition relay. The trouble is revealed simply. In this case, the fan does not work properly and is noisy; its effectiveness is expressed only when the engine is fully warmed up. To eliminate this failure, it is necessary to replace the relay.

• Inoperability of the stove speed modes;

It is detected when the fan is operating at maximum mode, which makes noise. In this case, it is necessary to evaluate the performance of the heating resistor. If it becomes unusable, replacement will help. This is the design of the heating system. In modes 1-2, the equipment operates using an additional resistor, and only mode 3 is switched on directly from the battery.

THE FAN MOTOR IS NOISE AND IS INTERRUPTED

• This indicates a problem in the VAZ 2114 fan cooling system, but provided that the above problems are corrected. The cause of a motor malfunction may be: equipment failure, or poor contact, which occurs as a result of sticking fan brushes;

The result of troubleshooting may be a complete replacement of the motor, which has repeatedly begun to fail you.

• Problems lie in the operation of the power unit;

This may happen if there is no power to the motor. Problems should be looked for in the following:

1. Poor contact on the fan.
2. Engine brush sticking.
3. Motor performance.

WHEN DO YOU NEED TO REPLACE THE ENGINE OF A VAZ 2114

The reason has been identified. All that remains is to act. Today the market provides a great variety of fans at your service. Their price depends not only on the manufacturer, but also on the quality characteristics.

Reviews from car owners indicate that fans purchased at an average price are the best option.

Instructions for replacing the stove motor

The procedure for replacing a heating system motor is also not an easy task. But if you are used to repairing a car with your own hands, then it will not cause you any difficulties.

To replace the heater motor, follow these steps:

1. First you need to dismantle the dashboard. To do this, disconnect all the necessary fasteners and unscrew the bolts on which the control panel is attached. Disconnect the device from all connectors and plugs and set it aside. All work on the control panel must be carried out carefully to prevent damage to this unit.
2. When the instrument panel is removed, it is necessary to dismantle the steering column beam. You will need a standard plumbing tool for this.
3. Having done this, you can dismantle the heating device itself, as well as the cooling unit. When removing, also be careful not to damage these system elements.
4. After these steps, it is necessary to remove the electrical wiring retaining clip from the upper chamber of the intake flap. It should be noted that quite often problems in the operation of a particular mechanism are caused precisely by electrical circuit malfunctions. Therefore, when removing the wiring, be careful not to damage the circuit. If you see that the contacts in the plugs have begun to oxidize, then they must be cleaned immediately, this will avoid possible problems in the future. Use a construction brush to clean the contacts.
5. Next, following the diagram, you need to disconnect the connector marked with the letter B from the damper motor. Having done this, you need to unscrew the mounting bolts A from the housing of the heating unit and the cooling unit using wrenches.
6. After these steps, you can dismantle the intake flap motor, marked 1 in the diagram.
7. Then you should remove the air conditioning system motor.
8. The system venting device moves slightly to the right, after which you can remove the mounting pin along with the elbow. Having dismantled the stove motor, you need to connect a new device instead of the old one, fix and connect it. Mount the engine as securely as possible, this will prevent vibration and, accordingly, more accelerated wear and failure. After installation, further assembly is carried out in reverse order.

HOW TO REMOVE THE FAN FROM THE VAZ 2114 OVEN?

To do this, you need to know where exactly it is. The fan is placed in a special container, which is located in the hood of the vehicle near the windshield.

To remove the fan you will need an ordinary screwdriver and a basic set of keys. Let's take a look at the step-by-step removal of the fan:

1. You should find the plus wire of the equipment. Disconnect it;
2. Since the casing cover is secured with screws, remove them completely;
3. Remove the casing and unscrew the screws;
4. Unscrew the screws that secure the air intake grilles;
5. Remove the engine of the VAZ 2114; to do this you will have to move it slightly towards you and lift it;
6. After removing the motor, rotate it 90 degrees. This is necessary to remove it from the casing and remove it.

As you can see, replacement is not such a difficult matter. Therefore, these works are easy to do yourself.

WHAT TO DO IF HEAT TRANSFER FROM THE OVEN IS LOW

Unscrew from the side of the passenger dashboard. Carefully inspect the hoses coming from the stove. Assess the degree of their heating. If they are cold, this means they are clogged and need to be cleaned. After cleaning them, take care of monitoring the engine using the sensor.

What to do if the replacement did not produce results and the motor still refuses to work?

To avoid unforeseen situations, the best way out of their situation is to contact a car service.

Price issue

And although the procedure for replacing a heating system motor is not particularly complicated, not every motorist can cope with such a task. Therefore, many vehicle owners have to pay for such a service. If you decide to seek help from a service station, then you will probably be interested in learning about the cost of the service. Depending on the region of residence, it may differ radically. For example, if in Moscow you pay from 4,500 to 6,500 rubles to replace a motor, then somewhere in Rostov or Nizhny Novgorod this procedure will cost from 1 to 4 thousand rubles.

How to remove the noise of the VAZ 2101-2107 stove fan

With the arrival of cold weather, it is necessary to turn on the heater fan more and more often, otherwise the windows will instantly fog up, or in order to quickly warm up the air in the cabin, we need to drive it through the heater radiator.

So what starts to irritate us?

It's that nasty fan noise. It really gets on your nerves. But it’s one thing when he’s just making noise; although it’s annoying, it’s bearable.

But when this noise turns into a heart-rending scream, and on top of everything you’re still stuck in a traffic jam - that’s when something akin to hell begins. Today I will tell you how you can try to reduce the noise of the VAZ 2101 - 2107 heater.

First you need to figure out why this increased noise is heard. The most common case is that the lower part of the case may have come unfastened, which is secured with hooks, which are also called clasps. Check, and if this is the problem, then all you need to do to solve it is put these hooks back in place.

Common cases are also those when the protrusions that hold the clamps in the car simply broke off. If you encounter a similar problem, you need to buy a new heater housing.

It should also be noted that it may squeal due to uneven expansion ratios between the shaft and the brass. This squealing noise can occur at very low temperatures or due to fairly long use, and therefore wear. The way out of this situation is to replace either the electric motor assembly itself or the bushings, and subsequently process them using a rubber.

Squealing can be produced by textolite washers. They are installed to eliminate axial play. The washers are located on both sides of the motor shaft. But we’ll look at how to deal with all this right now.

To eliminate noise, you must first remove the fan and clean it from dirt and dust. Please note that such work is connected to the car’s electrical network, so before you start it, you need to turn off the ground. I won’t go into more detail on how to remove the fan, but rather I’ll go straight to the main thing.

Of course, the main task is to eliminate the axial play of the fan motor. You can do this using washers made of fluoropolymer or similar material. Necessary condition: minimal friction must be created between the materials. It will be very good if you lubricate the bearings with a thick lubricant that does not react to temperature. For example, you can use MS-1000 lubricant.

The next step is to disassemble the fan motor. After this, you need to make the required number of washers and lubricate them all, then assemble the electric motor back. Surely another option has come to your mind: eliminate fan noise using engine oil. However, remember that in this way you will only improve the situation for a while, but later it will be what it was at first. The problem is that motor oil is liquid and will quickly leak and dry out.

But after lubrication, things will be different. You will notice that the fan will work better, it will rotate quieter and faster, and in cold and low temperatures there will be no trace of the usual squealing.

I hope this article will be useful to you, dear colleague and car enthusiast. Good luck.

Video “How to remove the electric motor of the heating system in a Nissan?”

Detailed instructions for dismantling the electric motor, as well as troubleshooting the system, are given in the video below (author - Nadezhda HE).

On first-generation Nissan Qashqai cars, the J10 body produced in 2006, 2007, 2008, 2009, 2010, 2011, 2012 and 2013, as it turned out, has a number of problems with the interior air conditioning and heating system.

The culprit of all these problems is the fan - an electric motor that spins the impeller. Let's take a closer look at the reasons and the stove repair itself.

Reasons for refusal

If your heater does not work and the motor shows no signs of life, you definitely need to look into the system and find out what is wrong there. However, first you must clearly understand the reasons for the failure and whether the motor can be repaired. Let's look at the main problems.

1. Fuse failure. If a short circuit occurs somewhere in the circuit, the fuse will save the fan from damage. Replacing it is completely easy and there is no need to buy a new device. However, it is also important to find out exactly where in the circuit the short circuit occurred and for what reason. If you do not solve this problem, the next installed fuse will blow in the same way.
2. Poor contact in the mounting block. This malfunction occurs on a wide variety of cars, and the VAZ-2114 is no exception. Most likely, oxidation has occurred.
3. Problems with the ignition relay. The motor turns on only after the car has warmed up. If such problems occur, you should check the relay, which is most likely sticking. Replace it and check if the heating works.
4. Heating operates only at third speed. A feature of the fan power circuit is direct connection only at speed 3; other modes are connected through a resistor. If you encounter such troubles, then it’s time to replace the resistor.

The above list of “diseases” is far from complete.

There are other fan malfunctions, but we will not dwell on them in detail. Next, we’ll talk about how to dismantle a part for repair or replacement.

Problems and reasons

We have been hearing about stove malfunctions in this Qashqai for a long time. Three main symptoms of malfunction: the stove does not blow (does not heat), the stove does not change speed or makes strange sounds (whistles, squeals, squeaks).

The main culprits for these symptoms are:

1. The stove motor does not blow: the brushes are worn out/lamellas are worn out/the winding is burnt out - change the motor or the transistor is burnt out - change the transistor or the thermal fuse in the transistor block is burnt out - change the thermal fuse.

2. The stove motor does not change the rotation speed: the transistor has burned out - change the transistor.

3. The stove motor squeals: the bushings are worn out - change the motor. I don’t recommend changing bushings for bearings - there are a lot of difficulties, the result is not very good.

Selection and prices

There are plenty of options to choose from. In different stores the prices for the motor will be different and on average its cost is 3000 - 4000 rubles. You can buy it at car wrecking yards for half the price.

The motor is sold with the housing and impeller assembly. The Nissan Qashqai (J10) and X-Trail (T31) models have the same ones.

The original Qashqai heater motor has not one number, but five:

27225-ET00A, 27225-ET10A, 27225-ET10B, 27225-JD00A, 27225-ET00B

Original heater motor XTrail two numbers:

Moreover, all seven numbers are the same spare part!

If we have to make do with replacing the transistor, we purchase a new one for independent repairs or at the request of the technician. The following options are suitable:

IRFP064N - 55V, 98A - recommended for purchase. IRFP064NPFB - 55V, 98A - this is a modification, recommended for purchase. IRFP044 - 60V, 57A. IRFP054 - 60V, 70A - can be taken. IRFP048 - 60V, 70A - can be taken. IRFP250N - 200V, 30A - this one burned out in a day, the current is not enough.

The average price of a transistor is from 95 rubles. up to 200 rub.

Heater fan motor replacement services and cost. This procedure is quite labor-intensive and requires certain skills. Therefore, it is better to trust those people who have experience in such things. At service stations, the work will cost about 2,000 rubles, without the cost of a new engine.

If you wish, you can make the replacement yourself, but it will take much longer than it will take in the service department.

Heater fans for any cars at Elektrik-Service

The assortment of our warehouse allows us to cover the needs of the Kaliningrad region with a 90% probability - regardless of what brand of car comes to us: BMW, Nissan, Renault, Honda or Lexus. You can even buy a rare stove fan from us: extensive experience in repairs allows Elektrik-Service’s craftsmen to select an analogue from the catalog.

Although a heater fan is usually a fairly simple device, there are some installation considerations that can affect the life of the fan and its associated devices. A burnt or oxidized connector or a clogged cabin filter may cause you to re-purchase a heater motor or rotation regulator. Therefore, we recommend installation in our car service center at the spare parts store.

Elektrik-Service specialists will not only replace the part, but also create conditions for its long-term guaranteed operation. Call us and we will schedule repairs at a time convenient for you.

Personal recommendations

Stove repair

Well, now let’s look at the process in more detail, for those who found free time (3-4 hours) and decided to make the replacement themselves.

We remove the minus from the battery. Remove the left side panel of the center console (it has two latches), remove the lower part of the panel under the steering wheel. To do this, disconnect the cable to open. hood, unscrew the self-tapping screw with a T20 torx, and begin to gently release the latches; it is better to first crawl under the panel and determine their location.

Having disconnected the panel, disconnect the connectors from the left block of buttons (mirror control, chandelier, ESP...), unscrew the T20 torx from the climate sensor.

Next, we lie down on our back and climb to unscrew the two 10mm bolts. Without removing this piece of hardware, it will not be possible to remove the pedal assembly. (the place of emphasis is circled).

Remove the bracket and pull out the pin.

Disconnect the connectors from the brake pedal end switches and from the throttle sensor, unscrew the 4 13mm nuts and take out the pedal assembly. (place of emphasis is circled)

We open the cover and take out the cabin filter.

Here it’s time for someone to figure it out, either on their back or on their stomach, so we basically lie down and crawl to the right place with a flashlight.

It's getting closer

Here it is - the engine.

We remove the power connector from it, then squeeze the latch by touch and turn the entire motor counterclockwise.

There is enough dust in it.

Now you can install a new motor and assemble everything in reverse order or repair the old one. Let's look at it from all sides. Below is the ventilation/cooling location for the motor brush assembly.

Unscrew the top nut by 8 and completely remove the impeller from the motor.

We see the blockage. The upper bushing is completely covered in dust and debris. Dirt deposits on the inside of the impeller.

It's even worse on the lower motor hub.

Now the task is to clean everything until it shines. Let's check the condition of the brushes, since we've come this far.

The brushes on this motor have not yet worn out.

Now let's get to the bearing and check its condition by cleaning the bushing. Remove the lock and other washers. We bend the petals and take out the bushing.

We check the noise of the bearing, if it whistles or hums, we replace it with a new one. Bearings suitable for this motor: SNR 608ZZ or SNR 608EE

We bend the petals even more, and change the bearing and bend it back. We screw the impeller. We return the motor to the car and assemble it.

The noise is eliminated, the operating speed is excellent, the stove heats wonderfully!

No one has answered the survey yet, be the first.

A very small number of cars can be called ideal and perfect, without flaws or weaknesses. The Nissan Qashqai cannot be classified as such a car, since the weak point in this car is the interior heating system. It is not reliable, it often breaks down and, as you might have guessed, this happens at the most inopportune moments. Of all the breakdowns associated with the Qashqai stove, we have identified the three most common:

1. The Nissan Qashqai heater motor does not blow due to worn brushes, lamellas or burnt windings. All these faults can be eliminated by repairing the stove motor. Also, the reason for this behavior of the system may be a burnt thermal fuse, which cannot be repaired, so it will have to be replaced with a new one.
2. The absence of changes in the rotation speed of the motor indicates a faulty transistor.
3. Replacement of the motor is required if extraneous sounds occur during its operation. This situation occurs due to worn bushings. Theoretically, they can be replaced with bearings, but this will not ensure quiet operation of the stove, and there are many difficulties.

How to replace the heater fan on a VAZ 2110-VAZ 2112?

Note! These instructions for replacing the heater motor are suitable for many cars of the tenth family, but not for all, because dozens were produced in very different configurations and designs throughout the entire time, some VAZ 2110 even had an engine from Opel installed from the factory, such a car is marked VAZ 21106, so we won’t be able to write about everything (since it will be a very long article), we’ll just take the most common tenth family and use its example to show how to replace a stove motor through descriptions and pictures!

1. First of all, you will need to get to the motor, it is hidden under a trim that is located under the windshield, and inside this trim, the motor is still placed in a casing, so you will have to remove a lot of decorative elements, in more detail how to do this is described in the article under title: “Replacing the cabin filter on a VAZ 2110” and by the way, the trim that is located under the windshield cannot be removed without removing the brush, and when you lift it, pay attention there will be a tee under it (see the location where it is located on the large photo), disconnect the hose from it that is connected at the bottom (see small photo) and the trim can then be removed from the car.

2. We go further, as soon as all the elements that prevent access to the casing in which the motor is located are removed, find the wires coming from the motor, or to be more precise, one “Plus” wire and one “Minus” wire, so here is the minus (Indicated in green arrow) is secured to the nut (indicated by a blue arrow), you unscrew it, but the plus (indicated by a yellow arrow) is connected to another wire through a wire block and a connector (see small photo), disconnect them from each other.

3. Then, using a flat screwdriver, pry out the four latches (They are indicated by arrows) that fasten two casings together, on one of which the stove motor is attached. Be sure to replace any latches that will be broken during their removal with new ones during reassembly. It is recommended to install all the fasteners in their places to prevent the housings from moving between each other.

4. And finally, unscrew all the screws that hold the casings together, there are only about 8 or 10 of these screws (We could be wrong), when they are all unscrewed, the casings can be separated (see small photo), but just remember where the screws go they are twisted because they have different lengths and you cannot wrap the long ones where the short ones should be located and vice versa.

Note! The stove motor can be removed assembled with the casing, or you can immediately take it out separately, it’s up to you how to do it, but having taken out everything assembled, it will be much easier to disconnect the motor (since it will be more convenient), and the motor is separated in the following way, you will only need just remove two wires (minus wire and plus wire) from the hole into which they are threaded in the casing and that’s it!

5. Installation is carried out in the reverse order of removal, after installing the stove, you will have to use the help of an assistant and find out whether you installed the stove correctly in its normal place or with a skew (If it is skewed, then this will need to be removed immediately), in general, closer to topic, ask an assistant or even get into the car yourself and turn on the stove, while assembling it, i.e. tighten the fastening screws (You don’t even have to tighten everything) and install the clamps and, of course, put the minus on the body, and connect the plus to the connector, then turn it on and if everything works fine in all modes, then turn it off and go tighten the last screws, install the covers under windshield and of course install the brushes, the replacement is complete, if after turning on you hear a crackling noise, then this only means one thing, namely that the heater blades are touching the body in which it is located, then turn off the heater and unscrew the screws , remove the clamps and remove the body together with the stove, place the motor there correctly, tighten everything again and try until the noise disappears, just like it disappeared, screw everything back and install all the parts in the reverse order.

What kind of motor can be installed on the Nissan Qashqai stove?

For a novice driver, the issue of purchasing new parts can cause many difficulties. To prevent this from happening, we have prepared a small guide that will allow you to buy the necessary part to replace the faulty one. Motor prices in retail automobile stores are in the range of 3-4 thousand rubles. If you take a used part, you can save up to half of this amount, but no one will guarantee long-term operation. Here everyone makes a choice at their own peril and risk. The heater motor is sold together with the impeller and housing. By the way, if you haven’t found a part for your car, you can buy a motor for the X-Trail stove, since they are identical. If you replace the transistor, you can choose from several options. First of all, you need to look for IRFP064N (55V and 98A) and IRFP064NPFB (55V and 98A). The second option is a modification. If these parts are not available, then you can buy IRFP044 (60V, 57A), IRFP054 (60V, 70A) and IRFP048 (60V, 70A). But you shouldn’t even look at the IRFP250N (200V, 30A), since this transistor can burn out within a day. The transistor will cost from 100 to 200 rubles.

Removing the heating system motor

It doesn’t matter whether the heater motor is replaced or repaired, in any case it will be necessary to dismantle this mechanism. The faulty part must be removed as follows:

The heating system engine has been removed; then a new mechanism can be installed or the old one can be repaired.

The process of replacing a fan on a VAZ-2114

As already mentioned, the process of replacing the stove fan will take quite a bit of time and even a novice motorist can do it.

The unit itself is located in the engine compartment, behind the engine shield. It is protected from dust and dirt by a plastic casing, which performs its functions well, but not always.

Before you begin the replacement process itself, you need to collect the tools. So, let's look at what you need: a set of keys (where would we be without it), a Phillips-head screwdriver and a new fan as a part.

Exact withdrawal algorithm

Now that the motorist is fully armed, you can consider the step-by-step instructions for replacing the heater fan:

1. We remove the negative terminal from the battery.
2. We find the fan power connectors under the dashboard and turn it off.

Unscrew the fastenings of the fan protective casing

The fan mounting screws are marked with an arrow.

Removing the air intake grille

Fan selection

Now that the process is clear and discussed, it is necessary to consider which stove fan is suitable for the VAZ-2114. To do this, first turn to the spare parts catalog. In addition to the original spare part, a number of analogues were found that are recommended for installation.

Original spare part (article)

2108-8101078 – original catalog number of the heater motor for the Lada family of cars 2108-21099, as well as 2113-2115. It is manufactured at the AvtoVAZ plant and the average cost is 2000 rubles.

In addition to the original stove fan, you can find several analogues on the market that are recommended for installation.

So, let's look at all the possible options:

• Fenox HM81002 – the cost of this product is 1,500 rubles. Country of origin: Belarus.
• Master-sport 2108-8101078-PCS-MS - the average cost is also about 1,500 rubles. Country of origin: Germany.

Fenox analog heater motor

Unfortunately, no other analogues were found, but some motorists are modernizing this unit by reworking it.

The whole assembly is assembled

Or they buy the entire spare part assembled, here are the part numbers:

Pekar 2108-8101091 is a very popular option among VAZ-2114 owners. Good reviews, cost about 1500 rubles.

Replacing the stove fan on a VAZ-2114 is quite easy and simple. As practice shows, most motorists do just that, saving their time and money. But, if the process seems very difficult, then it is recommended to contact the service, where they will do everything quickly and efficiently.

Motor repair

Don’t rush to throw away the old motor; perhaps you can bring it back to life. You will need to do the following:

1. There is a nut number 8 on top of the motor; it needs to be unscrewed, which will allow you to dismantle the impeller. She can sit tightly in her seat. If you apply a lot of force, the part will burst. You can warm it up with a hair dryer or treat it with a special compound.
2. A lot of dust and debris collects on the upper bushing, and dirt is deposited on the inside of the impeller. The lower motor hub will look no better. All these parts need to be cleaned until they shine.
3. We pay attention to the brushes, which are often worn out. We make replacements if necessary.
4. We dismantle the washers, carefully bend the petals and take out the bushing, which also needs cleaning.
5. We check the operation of the bearing, during which there should be no extraneous noise or hum. Otherwise, we replace it with a similar one. To replace the bearing, you need to bend the petals further and remove the faulty part.
6. All that remains is to assemble the motor and install it in its original place in the car. All steps are performed in reverse order. We check the operation of the stove, how the fan works, whether the intensity of airflow in the cabin changes due to temperature changes, how quietly the stove operates.

Of course, all this work can be entrusted to specialists. On the other hand, it is not so complicated that you would deny yourself the pleasure of tinkering with your favorite machine.

Fan disassembly

In the case where there is a motor with an impeller, we disassemble the fan housing. To do this, remove the foam seal from the outlet socket, then remove the housing clamps, after which it will split into two halves.

We extract the email. motor, for which we unfasten the spring clamps of the motor cover, remove this cover and remove the electric motor. the engine together with the impeller from half the housing. The electric motor is replaced only as an assembly with the impeller, and it is not recommended to disconnect them so as not to disturb the alignment. When assembling, be sure to stick a foam seal around the perimeter of the outlet socket, otherwise the air flow will dissipate due to the cracks, which will reduce the efficiency of the stove. If the electric motor of the stove made a strong squeal during operation, you don’t have to change the electric motor, just disassemble the fan and put grease in the bushings. But these measures will help eliminate the squealing for a short period of time and ultimately the stove motor will have to be replaced.

The VAZ 2114 stove fan is designed to force air into the interior heating radiator. After the air passes through the radiator honeycombs, it becomes warm and enters the car interior through the air ducts. If the fan fails, the entire heating system stops working correctly and its efficiency is zero.

In this article, we will analyze the process of replacing the VAZ 2114 stove fan, list the tools for the job, and also talk about choosing a fan and the reasons for the breakdown.
