Owners of cars, including domestic ones, are faced with the need to heat the interior in the winter season. If the stove on a VAZ 2110 car stops functioning, this significantly affects the level of comfort when moving. You can learn more about the device, operating principle, and repair of the unit from this article.
Reasons for replacement
A fan can fail for various reasons. Most often, he begins to howl. In this case, the problem is a bearing failure. If you do not take action, then after a while the engine will simply jam. The electric motor may also burn out. In any case, you will need to install a new fan. It simply doesn't make sense to repair it. This is quite labor intensive. At the same time, the reliability of the part after such repair is not too high.
The main malfunctions of the furnace in the domestic model VAZ-2110
Many furnace malfunctions occur during seasonal changes. With the onset of cold weather, drivers notice that the VAZ 2110 stove heats up poorly in their car or does not work at all. Nobody ignores this problem because it is always better to drive a warm car. Damage options that may require furnace repair include:
- Inability to control the heater temperature,
- Damper or gear motor faulty,
- Leaking in the furnace radiator,
- Failure of the ceiling temperature sensor,
- Malfunction of the SAUO control system.

Replacement
Before starting work, prepare the tool. You will need a standard set of keys, as well as several screwdrivers. Be sure to remove the negative terminal from the battery, this will avoid a short circuit. Replacement is carried out in the following order:
- The wipers are removed. To do this, remove the protective cap from them, after which the nuts securing the brushes are unscrewed with a 10mm wrench;
- Decorative plugs are removed. This allows access to the screws securing the frill;
- After unscrewing the screws, unscrew 2 nuts that additionally secure the frill. They are located at the edges;
- You will need to remove the seal. It is attached with self-tapping screws;
- The fastenings of the engine compartment shield are removed;
- We remove the windshield washer hoses;
- The next step is to remove the right engine compartment shield. To do this, you will need a 10mm socket wrench. You will need to unscrew 2 nuts. It is not necessary to twist them completely; you can remove the shield this way;
- Remove the clamps from the vacuum brake booster hose, and then simply pull out the shield;
- Remove the plastic stove cover. To do this, unscrew 4 screws and pull it out;
- Disconnect the connectors from the fan and resistor;
- We unscrew 3 screws, after which you can pull out the left side of the stove along with the motor;
- We remove the motor from the casing; it is secured with latches.
All that remains is to attach the new fan to the casing and reassemble it. Please note that when installing the motor from part of the stove casing, it may not be placed completely level. Be sure to check this point, otherwise you are guaranteed an unpleasant rattling sound when the stove is operating. The remaining removed parts are installed in the reverse order.
Problem solving
Eliminating the inability to control temperature
There may be several reasons for this problem:
- Control unit malfunctions,
- Damper failure.
Any of these faults will cause the heater to malfunction.
If the heater controller fails, the damper extension command may not be given. Therefore, you should immediately check the temperature sensor located near the ceiling light on the ceiling. To perform the test, turn the temperature control lever from left to right several times. The temperature of the air flow can be adjusted tactilely. This test is based on determining the operating state of the temperature sensor in the extreme position of the handle. If the flow temperature only changes in the extreme position of the sensor, it must be replaced. If it does not change significantly, you should look elsewhere for the cause of the failure.
Insulation Troubleshooting
To check the operation of the heater, it is necessary to remove the central deflectors. To do this, bend the special antennas and move the shutter manually. The latter can be reached through the engine compartment. When choosing this part, it is better to choose the aluminum version rather than the plastic version. The radiator of the VAZ-2110 stove requires the greatest amount of work when replacing it, because to do this you need to remove the entire stove. If you do the work yourself, you can save a lot of money. Read here in more detail on how to change a radiator.
Transmission Troubleshooting
When the heater fan begins to “drive” only cold air, then we can assume that the heater has failed. In modern models, dampers and adjusters rarely fail due to the fact that aluminum is already used for their manufacture at the factory. 90% of furnace failures occur due to the gear motor. This part is clearly replaceable.
In this case, car repairs are carried out in the following order:
- We remove the wipers, remove the protection,
- The protection moves away, using a short Phillips screwdriver we unscrew the three mounting screws,
- Unscrew the wires
- We connect a new gearbox,
- Bring it back.
It is better to carry out this type of repair with an assistant. This will switch the air flow from hot to cold and vice versa. After installation, the return parts are assembled in reverse order.
Eliminate poor hot air flow in footwells and side windows
This problem is very common on domestic cars. For this reason, feet freeze in winter and windows fog up. It is very difficult to drive in such conditions. The only way out. Modernization of air flow channels.
The procedure looks like this:
1. Make sure the oven is working properly. When it works perfectly, you can start upgrading.
2. Remove the panel and disassemble it into its component parts.

3. Solve the problem of side windows blowing out. This can be solved in two ways:
- Install a new corrugated hose.
- Glue all the slots on the panel.
To increase efficiency, it is better to choose the second option. We continue to work.
4. Glue all the gaps between the bottom and top panels to the squeak.
5. Glue all holes using fasteners.
6. We modify the furnace damper, which helps direct air to certain areas. At the factory, this damper is poorly pressed to the body, which is why some of the heated air is lost between the slots and goes somewhere on the panel.
7. Start dismantling the sash. Remove it and completely remove the yellow factory seal.
8. Glue the valve to the model and close all the cracks. This procedure will help the air flow out of the valve perfectly as intended. Instead of a sponge, it is better to use Bitoplast10 on the body, which sticks neatly in several layers.
9. The driver loses a lot of adult air on the way to the glass. This large gap must be covered by the installation. Doesn't squeak when moving.
10. We are upgrading the air ducts leading to the feet of the front passengers. The device that distributes the warm flow to the feet has a huge gap that needs to be repaired. For this purpose, the use of a corrugated tube is allowed.
11. We completely remove the standard air distributor from its original place, put corrugation in all the holes and fill everything with foam plastic. The diameter of the pipe used must be exactly 40 mm.
12. It turns out that corrugations will be installed: one for the passenger’s feet, the other. For the driver - the third. At the feet of the rear passengers. All this is installed on site and connected.
Troubleshooting an air heating furnace
In this case, you can improve some elements of the stove:
1. Replace the heater damper with aluminum. This will help retain heat and prevent fragments from deforming.
2. Replace the installed factory heater “2110-01” with the heater model:
- "2112-01." does not have a filter for air purification.
- "2112-02". Equipped with such a filter, but does not have an air recirculation function.
These filters can withstand a mileage of 15 thousand kilometers.
3. Install pre-heated heaters to warm up the engine and interior even faster.
For more significant damage, the hob may need to be replaced. Most often, replacement is carried out while setting up the VAZ 2110 with your own hands.
How to remove the VAZ-2110 plate and replace it can be seen in the video.
Minor improvements
In winter, motorists often have to drive with the heater on. Otherwise, it will be quite cold in the cabin, and the windows tend to fog up. At the same time, many car enthusiasts may be annoyed by the rattling sound when the stove is running, which is especially audible at the maximum operating mode of the stove. The problem here is in the lower panel of the heater housing. It is attached on peculiar hooks. On the one hand, this simplifies dismantling if necessary; on the other hand, these fasteners can be easily unfastened. After this, the panel begins to vibrate, causing unpleasant sounds.
To fix it, simply fasten the hooks in place. Sometimes they just break off. In this case, the only option is to replace the stove assembly.
If the stove does not heat well, then it makes sense to check how the radiator is warming up. It is necessary to remove the deflector; this is done using a slotted screwdriver. After that, start the engine and let it warm up. During this time, the radiator should heat up quite well. If this does not happen, then check the functionality of the heater valve. The reason may also be a clog in the radiator itself. It must be removed and washed. For this, it’s a good idea to use a strong solution of citric acid.
If you have a car produced before 2006, then it makes sense to install a pre-heater on it. This will allow you to quickly warm up the interior in winter. There will be no problems with installation, you will just need to purchase a heater designed for the injection “ten”.
Conclusion
. The heater fan in domestic cars is not very reliable. This is why you can so often hear the question of how to replace the stove fan on a VAZ 2110 and 2112. In fact, the work is not difficult, but due to the large number of small parts that need to be removed, the replacement can take several hours. At the same time, you should be quite careful due to the abundance of plastic parts.
Causes of malfunction
As a rule, there are many reasons for such a malfunction, these include:
- clogging with slags from;
- stove motor failure.
If the stove motor is not functioning, or some of its speeds are not working properly, then it is first recommended to check the resistor, which in other words can be called the stove rheostat. This element is responsible for the speed of the fan. You can purchase such a part in a specialized store that sells auto parts. As for replacement, this can be done with the help of a specialist or on your own, which is not so difficult even for an inexperienced specialist.
Note! In the case of repairing or replacing the heater radiator, it is recommended to contact a car service center, since it is difficult to remove the radiator yourself. To replace the stove motor, you will need minimal knowledge and detailed instructions.
There are heater malfunctions that can be easily fixed by any car enthusiast. For example, a situation may occur when cold air blows through the side deflectors and the windshield heating duct of the heating system, while a hot air flow comes from the lower and central air ducts. Most likely, the reason will be unsatisfactory performance, which is designed to cut off cold air. In some cases, it prevents the normal passage of cold air. Such faults are most easily identified during the cold season. When bending the damper drive rod, special care must be taken so as not to damage the plastic parts. Please note that plastic becomes more fragile in winter.
Of course, a non-functioning stove causes many problems in winter. If this is not so important in the summer, then in the winter the windows will fog up. You can figure out what the reason is by disassembling the heating system of the car.
