How long the heater motor lasts depends on the intensity of its use and conditions. If you actively load the climate systems and do not change the cabin filter, the problem may appear after 20-30 thousand kilometers . The most common malfunction of the stove motor is squeaking and squealing. To prevent this from happening, you need regular maintenance of the stove, its motor, and the entire climate system as a whole.
With gentle operation and periodic maintenance, repair of the stove fan may only be required after 100-200 thousand kilometers or more. The main signs by which such a need can be determined are noisy operation (crackling, whistling, howling, etc.) or vibration. If there are no signs of operation at all or the intensity of the air pressure flow from the air ducts has decreased when the climate control equipment is turned on, you will most likely have to disassemble the stove, check it and carry out more complex repairs.
Most cars are equipped with centrifugal fans (barrel-shaped) with a commutator motor, so checking the heater motor and restoring it in many cases is similar. Axial fans (propellers) are used only on old cars, like Zhiguli and Moskvich, and brushless motors are rare even among expensive foreign cars. Therefore, this article is devoted specifically to the collector motor of a stove with a centrifugal fan.
Removing and replacing the Renault Logan heater fan without dismantling the instrument panel
With a broken stove, people in the car feel uncomfortable, both in winter and in summer. The stove is required to create a comfortable temperature; it is used to get rid of condensation on the glass; without it, the stability of the engine may be impaired. More often than not, the heater motor fails, and the popular Renault Logan car is no exception. You can solve the problem of replacing the motor yourself.
The heater motor for Renault Logan is supplied by two companies - Renault directly and a third-party manufacturer Valeo, both of them are considered original. Modifications are offered for cars with and without air conditioning. The first ones have a little more power, otherwise their design is identical, so repair and maintenance are no different.

Ford Focus 2 remove the heater motor.
Ford Focus 2 remove the interior heater motor.
How to remove the interior heater motor on a Ford Focus 2. There are many articles on the Internet on how to do this. But yes, this is a troublesome matter, you need to stretch yourself a little.
First you need to open the glove box (glove compartment) there we see 7 screws that hold the box of the glove compartment itself. Having unscrewed them, we take out the glove compartment itself, and not the cover from it, which must then be removed. Next, we move on to the mounting block, which is located under the glove compartment. It needs to be removed from its mounts and moved to the side; there is no need to pull out the connectors. Why do we remove the mounting block to remove the heater motor through the bottom.
Let's move on to the most erotic work - we need to remove the interior air recirculation flap. It is attached with 3 screws to the block body.
Two of them can be said to be accessible and visible, but the rear screw will have to be turned by touch or through a mirror.
After we dismantled the recirculation damper, the heater fan itself opens to our eyes. Removing it is a little easier, but you need to go to the driver's side. We pull out the connector from the fan, feel for the latch next to it and, pressing the latch, turn it counterclockwise.
In my situation, there was an assumption that the fan control resistor burned out.
How to remove the VAZ 2114 heater fan or change the 2114 heater motor
First of all, replacing the VAZ 2114 heater motor is usually done when the heater motor is very noisy or has completely failed. So, the heater motor 2114 is located between the engine shield and the windshield (near the mounting block).
- Just open the hood and you will find the engine casing. This cover must be removed. Next, you need to clean the space around the housing from dirt and dust so that debris does not get into the air duct when you subsequently remove the heater motor.
- The next step is to use a cross-head screwdriver to unscrew the pair of bolts that attach the heater fan housing to the engine shield. After unscrewing the bolts, you need to remove the plus wire, after which the ground wire is unscrewed. These wires are located under the panel (almost in the center of the engine shield).
- Next, you can remove the heater motor. According to the manual, you need to turn it 90 degrees and pull it out, but in practice not everything is so simple and difficulties arise. To make the task easier, you can divide the body into two parts, and then remove one part and the other one by one. The main thing is not to break the latches by carefully opening them. It is also important not to damage the connecting elastic at the back.
Please note that during assembly you need to press the stove body as tightly as possible to the air duct. It is also important to connect the two halves of the housing tightly. This is necessary so that the air flow is dense and intense, without loss.
- It’s not difficult to guess that in order to change the stove fan of a VAZ 2115 or VAZ 2114, as well as a number of other similar models, you must adhere to the algorithm discussed above. Replacing the stove fan on a VAZ 2114 is also not particularly difficult and does not require special tools or skills.
Having prepared a new fan, you need to disconnect the terminals from the battery, after which the power to the heater fan is turned off. Then, under the hood, the bolts of the protective casing are unscrewed, and the “minus” of the motor power supply is removed.
After completing all the operations, you can remove the motor assembly with the protective casing. Next, you need to disassemble the casing, remove the motor and perform all the necessary work. Upon completion, reassembly should be carried out.
Operating principle of the stove
- The liquid is heated to a certain temperature and enters the radiator of the VAZ 2108 stove.
- To ensure constant circulation, rubber tubes are installed between it and the liquid cooling system, fixed for better fastening with clamps.
- Warm air enters the car interior through several openings. The heater motor with its own fan is designed to distribute air evenly.
- The air flows directly to the feet of the driver and passengers, and also exits to the panel. The heat flow is then delayed by the dampers, and therefore the air is cooled. Thus, cool air is supplied to the windshield.
If the operation of the furnace is not satisfactory, it can be modernized. This is done by installing fiberglass.
The action goes like this:
- It is necessary to disassemble the stove, wash all parts and begin assembly. This action can also be used to visually inspect parts for damage. For example, the casing ear often breaks.
- After this, you need to glue all the flaps and fill the seams with sealant. Glue the casing and wait a while until the sealant is stable.
- Assemble the “insides” of the heating system and cover it with fiberglass. Thanks to this, the temperature will increase to 10 degrees.
How to clean the heater air duct on a Renault Duster without removing the dashboard
The Renault Duster heater fan is not particularly quiet at speeds 3 and 4, but in normal working condition at speeds 1 and 2 it is quite quiet and vibration-free. Increased noise, vibration and crackling when the fan is turned on indicates that debris has entered the turbine, which needs to be removed somehow. Of course, the most effective option is to completely disassemble the front panel.
However, there are several ways to get rid of the noise and vibration of the stove on a Duster by simply cleaning the air duct. The essence of the technique is that we will try to blow through the ventilation duct and thus try to wash away the adhering dust from the fan, which leads to rotor imbalance, vibration and noise. There are no guarantees, but in many cases cleaning solved the problem 100%. Let's do it this way.
- Remove the protective grille under the hood.
- We find the air intake hole, it is almost in the middle of the engine shield.
- We remove the cabin filter, it is located at the feet of the front passenger.
- We set the heater to the foot blowing mode and turn on the 1st speed of the heater motor.
- Place containers to collect water on the front mats.
- We take a compressor, an air gun and a sprayer...
We carry out the purge procedure for about 30-40 minutes, periodically switching between operating modes of the stove motor. We spray water minimally, since it is still undesirable to flood the electric motor.
Car heating system design
The 2108 heating system consists of the following components:
- draft, which affects the heater valve of the VAZ 2108;
- damper control lever;
- additional resistor;
- a motor that affects the rotation of the fan;
- system operating mode switch.

KIA Spectra “CINΣɌO STAƝƝUM” › Logbook › ► Replacing the heater motor
Greetings, dear friends!
Exactly two years have passed since I disassembled the stove motor, cleaned it of dirt, rust and lubricated it. As a result, the motor began to work quietly, all extraneous sounds disappeared. And with the next arrival of cold weather, when the stove has to be used almost constantly, the familiar whistling sounds appeared again. And after a while it turned into some kind of loud grinding noise. It was decided not to put the matter off for long, and to carry out the necessary maintenance of this unit at the first opportunity.
To remove the motor, you need to disconnect the power plug and unscrew three screws. Next, pull the motor down, simultaneously rocking it from side to side. To get it out you need to apply force, since the motor housing rests against the front arch. Don’t be afraid to break the impeller in the process; it is made of nylon and is very durable. Some people lift the carpet and cut the standard heat and sound insulation underneath. By rocking from side to side, I quite easily removed and installed the motor more than once without additional disassembly of the interior. And even now, when the front arches are glued with vibration and noise insulation in three layers. You can read in detail about the process of removing and disassembling the motor in the article “Eliminating whistling of the stove motor”
.
Disassembling the motor showed that it was again clogged with dirt, there was practically no lubricant left on the rod, and some elements were again covered with corrosion.
However, the worst thing was that the rotor had a lot of play in the stator. The main thing is not clear why, since during the last disassembly I didn’t even try to remove the rotor. The fact is that the ends of the rotor rod are inserted into bronze bushings, which in turn are held in place by special plates rolled into the motor body. And if the lower part of the rod is easily removed from the bushing, then the upper part gets stuck in it and can only be removed together with the bushing, often breaking the retaining plate. Despite this, I tried to remove the rotor from the stator to try to bend the plates or then add spacers, however, no matter how much effort I put in, I still couldn’t do it. Since I need a car all the time, and in winter it’s very uncomfortable to drive without a working stove, I decided that in this case it would be easier to buy a new motor (fortunately, the prices for it were even more or less adequate at that time, I paid 1,610 rubles), and subsequently repair the old one and keep it as a spare or sell it for a nominal fee.
PART CODE:
The heater motors in KIA Spectra cars manufactured before approximately the first half of 2007 differ from those installed in the second half of 2007 and beyond (approximate data: 2007 was a transitional year in terms of parts, and this applies not only to the climate and heater systems). The difference lies in the presence of a corrugated tube and in a slightly different housing for the “newer” motors. In the Izhevsk KIA Spectra produced in 2006/2007, the entire climate is from the Doowon company, and from 2007/2008 onwards they began to install the climate from other manufacturers, in particular HCC (Halla).
● 0K2A161B10 — Heater fan motor (until mid-2007, without tube)
● 1K2N161B10 — Heater fan motor (after mid-2007, with tube) ( ATTENTION
, the information has not been verified, the code is taken from the body of a similar motor, order at your own risk)
Since I have a car manufactured in 2006 and there is no additional tube (corrugation) on my motor, I accordingly purchased a spare part with code 0K2A161B10
Important points
When replacing a heating fan on a VAZ 2107, you should remember several important nuances, neglect of which can ruin all the work. Here they are:
- When bending the plastic latches on the central panel and on the cigarette lighter panel, there is no need to apply much effort, since these latches are made of the same fragile plastic as the heating fan. They break very easily, especially if repairs are made in the cold;
- You need to be very careful when removing the motor after opening the latches. Behind it are wires with terminal blocks. If you pull such a wire carelessly, its terminal block may crack, since it is very thin. It is not possible to find this spare part for sale. Therefore, cracked pieces of plastic will have to be glued together using universal glue. All this can be avoided if you act carefully and slowly.
So, it is quite possible to change the stove fan on the “seven” with your own hands. Even a novice driver who has some understanding of the operation of automobile heating systems can do this. All you need to do is be patient and follow the instructions above exactly.
