Do-it-yourself replacement of the VAZ 2114, 2115, 2109 heater motor

When the heater motor of a VAZ 2114, 2109 makes noise or it stops working altogether, it should be replaced.

Where is the heater motor for VAZ 2109 2114? It is located between the engine shield and the windshield, in the same section where the mounting block is located. We open the hood and we can see the casing of the heater motor housing.

First of all, remove the heater fan casing.

After removing the casing, you will most likely see a bunch of leaves around the body. We remove leaves and all debris so that it does not fall into the air duct when removing the stove motor.

Using a Phillips screwdriver, unscrew the two bolts securing the heater fan housing to the engine shield.

Disconnect the positive wire and unscrew the ground wire of the heater motor. They are located under the panel, closer to the middle of the engine shield.

The smart books say: in order to get the stove motor, turn it 90 degrees and take it out. But in practice, for some reason I never succeeded. I simply divided the body into 2 parts and took them out one by one.

When you split the heater motor housing in half in the cold, the latches can crack, so it’s better to do this in a warm garage. To halve, you need to disconnect the 3 latches and remove the connecting rubber, which is located on the back side.

Also remove the sealing foam between the stove body and the air duct.

The stove motor cover is attached to the body with two iron brackets, which can be unhooked and can be changed. Don't lose them! On one bracket the motor will constantly dangle, hum and whistle.

Unscrew the two bolts with a Phillips screwdriver and remove the motor from the housing.

Installation of silent blocks of front levers

Collection occurs in reverse order. Remember that the more tightly the stove body is pressed to the air duct and the more tightly the body halves are connected, the stronger the air flow will be.

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.

Causes of failure

There may be several reasons for the malfunction:

The most common problem with a fan not working is a blown fuse. The fuse in the block should be marked F7 (20A). In addition to the stove fan, it is responsible for the cigarette lighter, heated mirrors and glove compartment lighting.

Fan selection

The original stove fan recommended by the manufacturer comes with a catalog number - 2108-8101078. It is produced in Russia and costs 1900 rubles. You can also buy analogues. These are fans from the manufacturers Fenox (HM81002) and Master-sport (2108-8101078-PCS-MS). Their prices are within 1500 rubles.

Tools for work:

open-end wrench for ten;
crosshead screwdriver.

Step-by-step replacement process

Open the hood and disconnect the negative terminal of the battery.
Behind the engine shield, unscrew the four screws securing the fan casing and remove it. Phillips head screws.

After removing the casing, remove the two screws that hold the fan housing in place.
Using a slotted screwdriver, open the latches and separate the plastic fan housing into two halves.
Disconnect the heater motor power supply terminal (it is located above the gas pedal).
Unscrew the nut by ten and remove the ground terminal of the heater motor (the terminal is located above the gas pedal).
After removing the wires, remove the fan along with the motor.
Unscrew the two screws and you will be able to remove the plastic casing.

After completing the above operations, the fan and motor are free. We take a new fan and reassemble it.

The process of replacing the VAZ 2113, 2114, 2115 stove fan is clearly shown in this video:

Let's summarize

As you can see, the process of replacing a fan is simple and will not present any difficulties for a driver who has held a tool in his hands at least once in his life. An independent replacement takes no more than twenty minutes of time, and the price of replacing a VAZ 2114 stove fan at a service station ranges from 200 to 500 rubles.

When a car's heater fails, the fan motor is often the cause. You can detect such a malfunction by the characteristic sounds that occur when you try to turn on the heater.

Examination

To make sure that the motor is the cause of the heating system malfunction, you should carry out a simple but indicative procedure:

Start the car;
Turn on the first, second and third speeds of the stove alternately;
If there are no sounds indicating the start of the fan operation, the motor has failed;
If the fan did not turn on at speeds 1 and 2, but started working at speed 3, then the cause of the problem may be a switch or an additional resistor.

Causes of failure

The motor may not work for several reasons. Each of them requires separate consideration. Therefore, we invite you to familiarize yourself with the possible causes of fan failure in our table.

Cause

It is important to know

The fuse F7 with a voltage of 30A is responsible for the stove. Replacing it is not difficult, but the main problem lies in the possible occurrence of a short circuit. This fuse is responsible for the lighting in the glove compartment, headlight washers, cigarette lighter, and heated mirrors. If it malfunctions, all specified devices will stop working.

There is no contact in the mounting block
This is a common problem in cars and occurs as a result of contact oxidation or loss of connection strength.
Ignition relay sticks

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. 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. 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. When the stove switches to different speed modes, the fan speed is regulated.
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.

How to independently remove and replace the stove on a VAZ-2115

20.02.2017

Heater malfunctions in any car cause a lot of trouble. It is especially difficult to correct the situation when the problem has already started and coolant has leaked.

Replacing a heater on a car is not an easy task, since in order to get to it, you will have to disassemble half the car and it will take a lot of time. Unfortunately, not everyone knows how to remove and replace the stove on a VAZ-2115, and therefore they turn to a car service center.

But you shouldn’t rush to give your car into the wrong hands because of this procedure alone, because:

Work to replace components costs about 1500–2000 rubles.
It’s not a fact that they will do everything efficiently.
Very often, car service workers treat their work anyhow and can break something when dismantling the panel.

The device of the VAZ-2115 stove

The VAZ-2115 and VAZ-2114 have the same heating systems; using the diagram below you can clearly see its structure.

44 — fan motor; 45 - additional resistance resistor; 46 - speed switch.

How to diagnose the performance of the VAZ-2115 heater

Turn on switch 1 first, then second and third speeds.
Using levers 2 and 4, you can adjust the desired direction of the air flow, and the latter also makes it possible to select the desired temperature.

The reasons for the breakdown may be different:

A faulty fan means the stove does not work at all.
If the radiator still shows signs of life, then the breakdown may be a failure of the additional resistor or the interior heater does not respond to switch commands.
But the stove tap can also leak or become stuck, in which case it must be urgently replaced.
When the fan is running at full power and the temperature is at maximum, and the engine is warm, then perhaps the heater radiator is clogged. To clean or replace it, you will need to disassemble it.

Replacing the radiator of the VAZ-2115 stove

Replacement is necessary when the heater radiator leaks or is clogged. If the radiator is clogged, you can blow it out with a Karcher, but keep in mind that it can deteriorate under high pressure.

How to disassemble the stove and remove the radiator

In order to remove the radiator, you must first drain the coolant and disassemble the dashboard. If the coolant is still good, it can be refilled again after replacing the failed elements.

To save time, you don’t have to remove the panel completely, but just do partial disassembly.

As you can see, removing the device is not difficult. Having studied the condition of the fan motor, we can draw a conclusion regarding the need to replace it. Sometimes car owners get by with simply repairing brushes or replacing fuses.

Withdrawal procedure

Before removing the VAZ-2115 heater fan, for safety reasons we disconnect the terminals from the car battery (you can only remove the negative terminal for this).

Then, inside the car, under the instrument panel, remove the protective side cover on the driver’s right leg side. It is attached from the bottom and top with two self-tapping screws.
Now disconnect the installation wires. We open the terminal of the positive wire (usually it is blue), located there at the location of the heater. To remove the ring terminal of the negative wire (usually black), unscrew the nut holding it with a wrench, remove the washer and the terminal itself. If you plan to change the part completely, you can cut the wires, as they are quite short.
In the engine compartment, unscrew the two screws securing the casings that cover the part, and remove this protective casing.
We unscrew the two screws securing the part that hold the protective casing (sometimes called a stocking) on both sides.
Pull the wires out of the rubber seal.
We lift the fan and disengage its front support from the car body. We move the part towards ourselves, and then turn it 90 degrees towards the passenger seat until the recess in the body widens. We take the part out.
If debris has accumulated inside or the electric motor requires repair or lubrication, then we disassemble the fan casings. To do this, release their latches and separate the parts. Now we remove the motor itself with the impeller.
Assembling the part and installing it in the car is carried out in the reverse order.

The removal process can be clearly seen in the following video: “How to remove the VAZ 2115 stove fan: video instructions.”

How to Replace the Heater Motor on a VAZ 2114

A warm interior is the key to good and comfortable travel by car. A non-working stove can not only cause discomfort, but also become an argument against future travel by car in general.

It’s nonsense when you came to the garage, saw a non-working heater and refused to move the car further during the breakdown, but if this breakdown caught you on the road, it’s a long way to the nearest service center, and you can’t drive a car with a non-working interior heater, because .

the windshield becomes covered with frost and the upcoming movement becomes dangerously unsafe. Then the only option is to transport the car using a tow truck, or try to fix it yourself.

The primary task is to identify the cause of the breakdown and assess one’s own abilities in a certain situation.

Let's start with the usual and move on to the more complex:

We check the fuse (F-7 with a voltage of 30 A), which is responsible not only for the heating system, but also for the operation of: the cigarette lighter, heated mirrors, glove compartment lights, and headlight washers. Therefore, when this fuse blows, they refuse to work, leaving our client to make the devices listed above. If it is working, we move further along the chain.
Turn on the car's ignition and switch the speed control to position 1, 3.5, 3, all in order. If the fan does not work in these positions, we move on.
When the electric motor does not show signs of life in the first and second positions of the speed switch, but starts working in the 3rd position (the fan is powered at the first and 2nd speeds through a resistor, and at the third speed the current flows directly to the electric motor), the problem lies in the resistor or in the switch itself.
If the heater electric motor turns on after the car engine has warmed up, then the problem lies in a faulty ignition relay. Solved by changing the relay.
If the heater electric motor refuses to work in all modes, one fault remains - the heater motor itself.

For the final verdict, let’s apply “” directly to the motor, removing the positive wire terminal from the motor for this purpose. If the motor does not come to life, the last thing to try is to clean the place under the ground mount on the electric motor. Often this place oxidizes and the contact weakens.
