A car refreshed in this way will not only please the owner with increased dynamics, but also requires lubrication. Thin steel surfaces, being weighted by an amorphous material that has no inherent rigidity. The photo clearly shows the possibility of combining installation options. During installation, special attention should be paid to the intersection of the brackets and the seat belts, as the brackets may severely damage the seat belts.

When you clean the brake mechanism from dirt, do not under any circumstances use such things as gasoline, diesel fuel and similar substances, do not use solvents either, just take a brush and use it to thoroughly clean the drum of dirt and then apply 40 to all joints. A key of this size is rarely available in stores that sell tools. For example, chiptuning is a more economical option and allows you to increase power by 10. If you naively trust the manufacturer and hope that the wheels are selected based on which, first of all, you need to think about safety when driving on the road.

Another typical mistake of many motorists, those inside wear out over time, metal shavings appear and the lubrication properties deteriorate. And on a flat level, if you throw the steering wheel, it doesn’t throw straight, then it’s not the wheel alignment and the pressure in the wheels; roll a branch; I had the same rubbish on my classic. Almost everything was repaired in factories, and the ground down gear teeth were fused and restored. Press the output shaft rear bearing out of the transmission rear cover by lightly tapping the outer bearing race with a hammer. It is impossible to say that the Swedish suspension provides a fabulous advantage in a class where adjustable struts are prohibited; you can get the most out of even our products.

It is necessary to take into account that the final mark of the regulator is of great importance; check the installation of the adjusting washers, as well as the position of the gears themselves.

As you know, the purpose of the heating system is to provide more comfortable driving. In cold weather, operating a car with a faulty heater will be virtually impossible, since the heater simply will not be able to warm up the interior. What is the heating system of the VAZ 2112 16 valves, what malfunctions are typical for it and how to replace the radiator - detailed instructions are presented below.

Heater valve VAZ 2110

Replacing the stove tap on a VAZ 2110

There is a possibility that most users of VAZ 2110 cars will not be able to find this tap in their car. It was installed on earlier and recently released modifications of the car, and therefore, if the model was purchased not so long ago, then this mechanism may not be in this place. Although, some craftsmen manage to install a similar mechanism on their car. The heating system is one of those that most often breaks down. This part of the car allows you to drive the vehicle in different weather conditions with increased comfort.

This stove tap is adjusted remotely. In versions of VAZ 2101 - 2110 cars, this mechanism is one of the most frequently broken. After each trip, it is necessary to constantly monitor its valves. This is necessary to eliminate leaks. As soon as leaks are discovered, the equipment must be replaced immediately.

Note. It was this fact that forced the manufacturers of the VAZ 2110 to abandon the crane. But after modernizing the crane, they began to install it again.

Replacing the faucet

To carry out work to replace this equipment, you must have a special tool on hand. You will need:

After each tool is ready, you must immediately begin replacing it. For this purpose, you must use the following methods:

• The engine must be drained of coolant.
• The heater has two hoses. They are secured with clamps. Liquid swells from one and flows into the other. These clamps need to be slightly loosened, but not completely unscrewed.

Note: if the valve is replaced due to insufficient sealing, then, most likely, all the coolant has already managed to drain into the car interior before the repair is carried out. This problem can be detected if there is a puddle of the same liquid under the passenger seat rug. Also, if there is no coolant in the system, a constantly cold air stream will flow from the stove.

An undoubted companion to a fluid leak is the presence of a specific odor in the cabin.

• The two bolts are unscrewed with a key marked “7”.
• The rubber insulation is removed.

Note: the bolts must be unscrewed carefully, since the fastener itself is plastic and the slightest failure in the thread can lead to major complications.

• The body is removed from the box.
• The duct has a bracket nut that needs to be removed. A wrench with the number “10” is used.

Electric stove faucet

• Using a screwdriver, you need to disconnect the clamps on the heater body.
• The right air duct is disconnected first.

Note: the right air duct has a specific “body”. If necessary, you can fold it a little.

• The faucet has a fastening in the form of two nuts. They are removed using a wrench that has the number “10”. These bolts secure the faucet to the car's radiator.

Note. Some cars have a plastic reservoir. It has a fastening that is locked into cage nuts. You must always be careful here, since the lower nut has the ability to fall out.

When it becomes necessary to assemble this device, it is necessary to disconnect the two springs that secure the stove fan housing on the tap side. After completing this procedure, you need to slightly lower the body down and “tighten” the bolt nut. After which it must be clamped.

Assembly occurs in reverse order. It is necessary to consider the replacement of all rubber, polyurethane and other gaskets. Also, it is necessary to use a special product for better grip. Standard sealant will do.

VAZ 2110 stove faucet and heater

The last step is to add coolant to the car. As soon as the liquid is poured into the car, it is necessary to start it. The temperature must be brought to 90 degrees Celsius. The tap is opened and checked for fluid leakage. If there is no leak anywhere, the replacement was successful.

The cost of such a product as a stove faucet for a VAZ 2110 is very insignificant. Even in the most remote cities of the country or small towns, you can find a similar crane without much worry. Detailed step-by-step videos and photos on replacement can be found on the Internet. The same applies to the equipment itself. If suddenly there is a need to replace the faucet, but it is not on sale in specialized stores or service stations, you can always place an order on the Internet. This crane will arrive after a few days, depending on the region. Payment can be made at the request of the customer or sales representative. It is necessary to prepare the car before starting work. To perform the work, it is necessary to place the car on a flat surface and secure it in one place. Also, the car should be completely cleaned of dirt. A sink is ideal. Care must be taken to ensure that water does not enter the engine operating systems. If you encounter even the slightest difficulty when replacing this faucet, it is better to contact specialists who will carry out this work for a small amount. As you can see, no special difficulties will arise when replacing the faucet yourself. It is advisable to do everything as required by the instructions. This way, you can avoid mistakes and save a lot of money, because the price of services from professionals is quite high.

Adjusting the heater dampers

By adjusting the dampers with your own hands, you eliminate the supply of part of the air “to the glass” when the lever that controls the air flow is installed in the heater in the “chest” or “legs” position. The photo shows the damper adjustment control units.

2 – adjustable rod for installing the damper “in the chest” – “in the legs” 3 – fastening the rod “in the chest” – “on the glass”. To do this, it is necessary to shorten the adjustable rod by three divisions, and use side cutters to bite off the tip protruding on it. After performing such operations, the heater damper will be in the desired position, and the heat from the stove will flow better in the given direction.

Replacing the stove tap with your own hands

Every motorist should be able to at least to some extent be able to maintain his car. This refers to a basic set of knowledge and skills that will help you save money on auto repair shops and prevent you from getting stuck in the middle of the road with a broken down car.

VAZ-2110 owners know firsthand about the problems that often arise with the heating system of this car. The weakest point in the heating system of the VAZ-2110 is the heater valve. Replacing it is not quick, but it can be done independently.

Installing a new faucet

The heater tap is not located on all VAZ-2110 vehicles. If your car is new, this item may not have been installed. Some cars may have a modified VAZ-2110 heater tap.

This device is regulated remotely, which cannot be said about the replacement process. Each VAZ-2110 owner must carefully monitor the condition of the valves, which will allow leaks to be identified and eliminated in a timely manner.

Basic Workflows

To replace an old tap with a new one, you will need a new element and keys for 7 and 10. Replacing the stove tap is carried out according to the following scheme:

1. Drain the coolant.
2. We find two hoses on the heater, which are secured with clamps. One serves for the outflow of liquid, and the other ensures its supply. There is no point in unscrewing the clamps completely; it will be enough to loosen them a little and easily dismantle them.
3. The VAZ-2110 heater valve may require replacement due to depressurization. In this case, there is a high probability of coolant leaking into the passenger compartment. If this situation occurs, then there will be a puddle under the carpet near the front passenger seat, and a characteristic odor will be present in the cabin.
4. We will continue to work on replacing the faucet. At this stage you need to unscrew a couple of bolts. A size 7 wrench will come in handy here. This will allow you to remove the seal. When unscrewing the bolts, care and caution will not hurt, since the fastener is made of plastic, and malfunctions may appear on the threads.
5. Remove the body from the box.
6. There is a bracket nut on the air duct, which must also be dismantled. At this stage you will need a 10mm wrench.

• There are clamps on the heater body; they will need to be disconnected.
• First of all, you should disconnect the right air duct, which due to its specific design can be a little complicated, which will make the work easier.
• There is a bracket with a fastening on the flexible cable, which just needs to be loosened a little.
• On the stove tap on the VAZ-2110 there are two nuts that serve as fastenings. To remove them, it is convenient to use a 10mm wrench. The valve is attached to the radiator using bolts. In some cars you can find a plastic tank, which is secured using cage nuts. The bottom nut in this design often falls out, so caution and attentiveness will not be superfluous. When assembling a device with this design, you will need to disconnect a pair of springs, due to which the fan housing is attached to the side where the faucet is located. All that remains is to lower the body a little, pressing down on it, and tighten the nut of the bolts.
• Now the tap can be easily removed and replaced with a new model.
• Assembly is carried out according to the same scheme, but in strictly reverse order. It is advisable to replace all gaskets with new ones. They are very inexpensive, but the heating of the car will annoy you less with its poor quality work. To ensure maximum adhesion, you can use special sealing agents.
• Our work is completed by pouring coolant into the system. After this, we start the car and bring the temperature to 90 degrees. Open the tap and look for possible leaks. If there are none, the replacement of the tap can be considered complete.

Now you not only know where the heater valve on the VAZ-2110 is located and how to open it, but you can also replace it with a new one yourself. When doing this work for the first time, difficulties may arise, and it will take a little more time. But in the future, you will already know how the heating system of your car is disassembled and will be able to quickly eliminate problems of a different nature.

Disassembly and assembly

Replacing faulty parts in a VAZ 2110 heater is not very difficult, requires a minimum of tools, but takes a lot of time. Almost all work is carried out from the engine compartment, where the heater is mounted on the engine panel.

To gain access to it you need to dismantle:

• Engine shield insulation;
• Plastic trim under the windshield (“jabot”);
• Windshield wiper mechanism;
• Left and right heater covers.

The resistor is located on the right side (if we stand in front of the bumper and look at the engine compartment), it is secured with a screw. To get to it for replacement, you will have to remove the vacuum booster.

The cabin filter is “hidden” on the left in the opening inside the car; you can simply reach it with your hands.

The “old” and “new” non-interchangeable options were used; to replace, purchase a filter similar to the one installed.

To replace the heater and faucet on a VAZ 2110, you must first drain the coolant. To remove the stove, you need to disconnect the two pipes on the clamps and the steam exhaust hose. The stove itself is not attached and is held in place only by pressing the lid against the heater body. You can replace it with copper or aluminum, the former heat much better due to the high thermal conductivity of copper, the latter are more durable and cheaper.

At the tap, you need to disconnect two more hoses, which can be accessed from the interior by removing the glove box (“glove box”). The tap itself is attached to two 10mm nuts; before removal, the drive cable is disconnected. When replacing, new rubber seals must be installed.

Assembly is carried out in reverse order, the entire process can take more than four hours.

the engine to warm up faster in winter . and in the summer, get rid of the heat from the stove .
We will look at how this can be done in this article. The meaning of the idea is this: In winter, you warm up the engine without one and a half liters of antifreeze from the stove, thereby increasing the heating rate of the internal combustion engine and the engine life. In summer, hot air does not seep through the cracks in the heater dampers and does not heat the already heated interior.

Required:

1. VAZ 2108 stove faucet
2. Choke cable from VAZ 2108

A faucet with a sawn-off non-closing pipe is secured with two clamps on any stove hose.

When doing this work for the first time, difficulties may arise, and it will take a little more time. But in the future, you will already know how the heating system of your car is disassembled and will be able to quickly eliminate problems of a different nature.

Removing the heater radiator

Your first priority is to get rid of the antifreeze. It is better to drain the coolant into a clean container if you filled it recently and it is in good condition. This will allow you to refill it later.

1. Relieve pressure by opening the expansion tank cap. Just let the car cool down before doing this.
2. Next, behind the ignition module, find the plug that needs to be unscrewed.
3. You should have about 4 liters of coolant coming out of the hole. Therefore, prepare a container of appropriate size.
4. Or you can drain through the expansion tank. Although this option is not particularly convenient.

Let's consider both options separately.

Old stove

The radiator is removed from the engine compartment. This is done as follows:

• Remove the rubber frill seal;
• Under the brake master cylinder, locate the fasteners that hold the frill in place. Unscrew it;
• Now remove the screws that hold the right side of the frill in place. There should be four of them in total;
• Disconnect the two small clamps on the frill. They hold wires and hoses;
• The positive terminal and negative wire are disconnected from the fan;
• Move the left side of the frill forward a little, but you don’t need to remove it completely. All you need to do is unscrew a couple of fasteners;
• Remove the wind cover;
• If there is a coolant level sensor terminal, disconnect it;
• Remove the steam exhaust hose from the expansion tank.

Removing thermal insulation

Next, you need to remove some elements one by one. Proceed strictly in the specified sequence.

1. Windshield washer hose.
2. Wipers.
3. Windshield trim. Heater housing clamps.
4. Front part of the heater with fan.
5. Cabin filter.
6. The second part of the case is the fan.
7. All hoses (steam outlet, return and supply).
8. Radiator housing.

So we figured out how to remove the heater radiator on an old-style VAZ 2110. When installing a new unit or a repaired old one, make sure that the pedal of the plastic housing from the fan fits into the groove. If this is not done, the gearbox will not be able to change the position of the damper. Consequently, there will be no heat inside the cabin.

In addition, it is better to replace this plastic pedal with an aluminum one. Not expensive, easy, but reliable and durable.

New stove

If you are dealing with a new type of stove, there are some nuances regarding fixing the heater to the body.

To remove the unit, you will need to dismantle several elements. Namely:

• There are screws at the bottom of the windshield, the middle one can be unscrewed;
• Also unscrewed is a pair of nuts that you will find slightly above the intake manifold;
• The nut located to the left of the filter must be removed;
• If there is a reservoir with washer fluid for the rear window, then it and the air filter are removed.

Stove 2110, do-it-yourself installation and repair of the VAZ 2110 heating system

As a rule, car owners remember about a failed interior heater only after the arrival of cold weather. One fine cool morning you are trying to heat the car interior, but the heat is not coming out. You don’t want to freeze in your car, but going to a service station is very expensive. What to do? In this case, repairing your heating system yourself will help you save your budget. More on this later in the article.

VAZ 2110 stove faucet

Replacing the heater tap on a VAZ 2110 is not an easy task. It requires knowledge of certain nuances. Nevertheless, replacing the valve of the VAZ 2110 stove can be done independently. This will be discussed in this article.

Heating VAZ 2110, design and principle of operation of the stove

The heating system of a VAZ 2110 car consists of: an electronic control unit for the heater, operating from the passenger compartment, air ducts that extend from the stove, and a heater unit that provides heating for the interior.

The heater unit is represented by the following elements:

1. An electric motor on which a fan is attached to pump hot air.
2. A radiator, without which the system will not work. At the same time, unlike the old-style heater, the radiator of the new VAZ 2110 stove does not have a tap that shuts off the flow of antifreeze (antifreeze) through the radiator. As a result of this, it is always (whether in summer or winter) heated. This was done to eliminate leaks, which are often observed through this faucet, and also to heat the interior as quickly as possible, if necessary. In the summer, fresh air ventilation goes past the radiator, but some VAZ 2110 car owners add this valve to the system when repairing the stove.

3. Three dampers, one of which closes/opens the heater duct, the second is responsible for air intake recirculation, and the third, most important for the interior, controls the heater.
4. A resistor that regulates the blowing speed.

Diagram and explanations for it

Below is a diagram of the parts that make up the heater system of a VAZ 2110 car.

It is worth saying that recirculation operates in the “tens” heater system, as the diagram tells us. In simple words: air circulates inside the VAZ 2110, and is not taken from the street. The main advantage is that dust and unpleasant odors do not enter the cabin from the street. There are more disadvantages to such a stove system - the glass quickly fogs up. It is recommended to open windows more often if the outside temperature allows it. Air stagnation negatively affects the health of the driver and his companions. The heater gear motor can rarely be repaired, so it should be replaced immediately.

For VAZ 2110 owners who want to modify the heater system or carry out electrical repairs, an automatic control circuit will be useful.

Reference information from the Operating Manual: To speed up the warm-up of the cabin and prevent the entry of outside air into the cabin (when crossing gas-filled, smoke-filled, dusty sections of the road), an
air recirculation system
.
When the recirculation button is pressed down (on the instrument panel), the electro-pneumatic valve opens, and under the influence of vacuum in the intake manifold, the recirculation system flap blocks the access of outside air to the car interior.
Thus, the recirculation system can only operate when the engine is running. At the same time, if the fan is turned on, the air in the cabin continues to circulate, passing through the heater air ducts. From the very moment I got into the cabin, this very button haunted me. I think many or some (of course, those who have a VAZ2110) have it, and even if they do, it works for only a very few, and for even fewer people it has any effect on the car. Finding out which category I belonged to, I realized that I belonged to the first. This is wrong, I decided. I'll do it. As an additional information used an article from the website lada2111.rf (Installation of air recirculation VAZ 2110)

Many people before me found out at what period the air recirculation system (hereinafter referred to as ARR) on the VAZ2110 was introduced, installed completely (damper, pneumatic valve, electro-pneumatic valve, hoses, wiring, button), partially (some of the above, most often only the pneumatic valve and button), or was not mounted at all. My (our) situation was further complicated by the fact that we do not have an ordinary car. But let's not talk about that now.

The SRV of this car contained: an old-style stove, without a filter, with a damper and a pneumatic valve, a button in the cabin and a wire from it connected to the connection block with the underhood electrical wiring harness. I’ll say right away that this happened at the beginning of autumn, and I might have already forgotten something, and lied somewhere, but not much.

Air ducts VAZ 2110, structure and why they are needed

1. Interior ventilation through central nozzles.
2. The air distributor is responsible for supplying heat or regular air for the purpose of ventilation.
3. There is a whole system for heating the feet, which consists of five nozzles.
4. Two air ducts are directed to the rear of the car interior.
5. Two side air ducts are responsible for heating the side windows, as well as part of the interior, which provides better heating.
6. There are also 2 nozzles for ventilation.

Furnace electronic control unit

The electronic control unit includes:

1. Controller handle. This device makes it possible to set the temperature in the cabin, which is produced by the stove unit. The controller handle sets the air temperature, which corresponds to that outside, and is turned on by turning the handle (up to 30 degrees Celsius). This part is usually called the ACS controller.
2. The temperature sensor controls the activation of the heater when the air temperature in the cabin decreases by 2 degrees against the set one. The sensor has a microfan, and when the control knob is located in position A, a micromotor in the stove block turns on, after which the damper begins to operate, which ensures proper heating. Therefore, before repairing the heating system, you need to check the operation of this sensor. It is located near the heating lamp on the ceiling. Since its repair is not provided, if it breaks, this device must be replaced immediately.

Stove fan.

The stove doesn't work at all

In this case, some node of the system has broken down. All components of the structure must be checked. But, as practice shows, the fan is to blame. If everything is fine with it, next check the thermostat. After checking all components and determining the malfunction, consider carrying out a major overhaul of the stove. Having repaired the system once, you will be able to drive comfortably for a long time without all sorts of surprises.

If the cost of a major repair is equal to the price of a new heater. Then the best way out of the situation would be to purchase and install a new unit. In this case, you will travel approximately 15 thousand kilometers without any problems.

To summarize the article, we note that we examined the main malfunctions that can lead to poor operation of the stove on the VAZ-2112. Now you know how to find and repair a heater failure. If you do not have experience in carrying out this type of work, the best solution would be to contact a service station.

Stove 2110, how the new stove differs from the old stove

1. The main difference between the new stove and the old-style stove is in the design of the radiator. Therefore, if, when repairing the heating system, you decide to install a new radiator, you should take into account some nuances.
2. In addition, the ACS controller also has certain differences. Thus, 4 and 5 position controllers produced before the fall of 2003 have already been discontinued and they are not suitable for new heater models.
3. Micro gearboxes manufactured before September 2003 also differ. The main difference is the resistors, so you need to pay attention to whether the resistor in the MMR model you purchased is interchangeable.

Drive problem

When changing the damper, do not forget to check the functionality of the actuator.

Drive unit

If the micromotor gearbox does not work, it will have to be repaired or simply replaced with a new one.

1. Having removed the trim and trim from the windshield, directly behind the vacuum booster of your “ten” you will find a micromotor gearbox. Disconnect two connectors from the amplifier - the micromotor and the micromotor-reducer. Now unscrew the screws and
2. remove the micromotor gearbox. You have to remove the motor from it.
3. Connect it to the automatic control system to check its functionality.

If the device does not work, you can try to repair it. For this:

• Bend the pressed side slightly and remove the lid;
• Check the condition of the commutator, brushes and bearings;
• Replace the specified components or correct them;
• If the gear teeth are worn out on the gearbox, it will have to be replaced;
• Be sure to lubricate the bearings. Ideally, a silicone-based lubricant should be used;
• If the above measures do not help, simply install a new unit.

Causes of furnace malfunction

1. The oven temperature is not regulated. The reason must be sought in the control unit or in the damper.
2. The ceiling sensor does not work.
3. The heater does not work, only cold air enters the cabin.
4. Hot air does not flow well to the side windows and/or to the feet.
5. The coolant level drops, which can happen either obviously (when it flows from the pipes or radiator) or covertly.
6. The stove works, but is very noisy.

Possible heater malfunctions and ways to eliminate them

What symptoms can you use to identify a malfunctioning heating system:

• antifreeze consumption has increased, the volume of liquid in the expansion tank is constantly reduced;
• the interior of the vehicle practically does not warm up;
• traces of antifreeze leakage began to appear under the bottom of the car, in the area where the radiator assembly was installed or the location of the pipes, and traces of refrigerant may also appear in the passenger compartment;
• greasy marks began to appear on the inner sides of the glass, the glass itself began to sweat a lot;
• the smell of refrigerant in the car interior (the author of the video is the channel In Sandro’s Garage).

For what reasons does the VAZ 2112 stove not work:

1. One of the most common problems is the failure of the radiator; there are two ways to solve the problem - either repairing the radiator device or replacing it. Repair is relevant if the damage to the device is not serious and its case can be soldered. But often the repair does not produce results, so the unit has to be replaced.
2. Failure of the gearmotor, that is, the stove itself. As for fixing the problem, here you need to act in accordance with the malfunction. If possible, then, of course, you should try to repair the motor itself, but usually it is replaced.
3. Antifreeze has run out. This problem is usually caused by a leak. A leak can occur through the radiator assembly, thermostat, or damaged pipes. If the radiator and thermostat are intact, then you need to check the condition of the hoses and especially their connections. If the pipes are cracked and show signs of damage, they must be replaced.
4. Thermostat failure. For this reason, although the liquid will partially circulate through the system, the stove will not be able to heat the interior. If the thermostat is not working, the device is usually replaced.
5. The heater control unit does not work, in particular, we are talking about the module located on the center console. If the control model refuses to work, the stove simply will not be able to receive signals about activation, shutdown and mode switching. If the problem lies in the unit, then it will need to be replaced, but often such malfunctions are caused by damage to the electrical circuit or poor contact of the device with the system.

If the temperature is not regulated, reasons and how to fix it

If you cannot adjust the temperature of the air that enters the cabin, the fault may lie in the temperature sensor located on the ceiling, near the ceiling light. To check it, turn the control all the way to the right, then bring your hands to the air flow that comes from the heating system. If heat flows no matter what position the regulator is in (in the red part), then the problem is not with the sensor. But, if air flows only when the regulator is located in the maximum heating position, it must be replaced (or the regulator itself needs to be replaced).

You also need to check the condition of the damper. You get to it through the engine compartment - you need to remove the central deflectors and move the flap by hand. If you have to remove it, it is better to replace the plastic one, which comes standard, with an aluminum one, since it does not freeze and deform so quickly.

Setting the temperature of the supplied air from the heater

To fine-tune the control unit, it has an adjusting screw. To check the accuracy of temperature control, close all doors and windows and place a control thermometer next to the temperature sensor. Set the fan control knob to position A, and the temperature knob in accordance with the temperature measured by the control thermometer. If after 15 minutes the actual temperature in the cabin does not correspond to the set one, remove the controller from the socket and turn the adjusting screw clockwise to increase the temperature and counterclockwise to decrease it. After adjustment, check the operation of the control unit again. The control unit, temperature sensor with microfan, micromotor and heater damper position sensor cannot be repaired and must be replaced with new ones if they fail.

Malfunction of the interior temperature sensor and controller in VAZ 2110 2111 2112 cars

1. If the interior temperature sensor is working properly, the heater operation algorithm should be as follows: at maximum (red dot) – movement to open the damper; at minimum (blue dot) – movement to close the damper, other positions are fixed depending on the temperature set by the interior temperature sensor. To see if the damper is moving, it is better to remove the front deflectors; they have two plastic latches on the right and left (be careful not to tear off the backlight wire when removing). After removing the deflectors, you can clearly see whether the damper is moving or not, i.e. air flows through the heater or not. In addition, you can check the resistance of the interior temperature sensor.

Checking the interior temperature sensor on VAZ 2110 2111 2112 cars.

Characteristic temperature - the resistance of the temperature sensor should be as follows: at 22 C - 20 Ohm; at 16 C – 25 Ohm.

Checking the controller with a heater (stove)

Checking the controller is as follows. We take out the controller from the socket. Turn on the ignition, turn the temperature knob and measure the voltage on the pink and brown wires (long controller connector). If the voltage changes (should turn on after changing the position of the temperature knob and turn off after about 13 seconds), then the controller is working, if not, then the controller needs to be changed.

The gearmotor is faulty, how to replace the gearmotor, step-by-step instructions

1. We dismantle the wipers.
2. We remove the frill.
3. Using a short Phillips screwdriver, unscrew the three screws that secure the gearbox.
4. Unfasten the wires.
5. We install a new gear motor in place of the old one, for which you should ask an assistant to switch the positions of the regulator while you are installing this part.
6. We install the frill and wipers back.
