How to remove the heater motor on a VAZ 2114

Appearance and location of the stove motor

The device is located in the middle of the so-called torpedo and is a small DC electric motor to which a fan protected by a plastic casing is attached. This motor has three operating modes and is designed to supply warm air to three zones: on the windshield, on the passengers’ feet, or directly into the cabin.

How to replace the radiator of a VAZ 2114 stove

We replace the radiator ourselves.
We start by draining the antifreeze from the cooling system.
Then remove the dashboard.
Replacing the heater radiator in a VAZ 2114 begins with the interior. Inside the car, under the dashboard, disconnect the hoses leading to the heater tap pipes.
To perform these actions without problems, loosen the clamps.
Do the same in the engine compartment: remove the hoses of the faucet pipes, unscrew the nuts securing the radiator, and remove the faucet from the panel.

And now in order

Loosen the clamps, remove the hoses, remove the radiator mounting nuts

Removing the rod holder
Disconnect the rod from the lever itself
We go into the interior, lift the cover from the gear shift lever.

We remove the trim trim: which is located under the handbrake.

We unscrew and take out the rear trim: located between the seats. We move it back for convenience.
Disconnect the air duct (cabin) from the heater housing and remove it.

Disconnect the cabin air duct

Disconnect the resistor and motor connectors.
Unscrew the nuts (2 pairs) to the left and right of the heater.

Nuts securing the heater

Remove the radiator along with the panel.
We are making a replacement.
We install the heater radiator in the reverse order of disassembly. We check the condition of the pipes and clamps and replace them if necessary. The replacement of the radiator with VAZ 2114 stoves has been successfully completed.
After replacing and installing all parts in place, fill in coolant.
We start the engine and check the functionality of the stove.
If suddenly the stove does not heat well, it means that an air lock has formed in it, you should get rid of it.

Another case when the stove does not heat:

Situation: A car owner’s heater does not warm up the interior well, although heated air is supplied, the engine temperature is within ninety degrees. The heating radiator is also hot, the pipes are in good condition. We do the following:

We independently unscrew the side of the dashboard on the passenger side.
We inspect two hoses located near the engine shield, extending from the heater. Let's try them by touch.
If they are cold, it means they are clogged.
We clean them and everything works!

When does the heater motor need to be replaced?

There are several signs that will tell a car owner that something is wrong with the heater motor. Here are the most common of them:

When you try to turn on the stove, you cannot hear the hum of the motor, and this picture is observed at all three speeds.
The motor supplies air at all speeds, but operates intermittently.
The operation of the motor is stable, there are no interruptions in the supply of warm air, but instead of a uniform hum, extraneous sounds are heard, a grinding sound, which later develops into a piercing creak.

Important points

In order for the stove repair to proceed as quickly as possible, and its results not to disappoint the car owner, you should adhere to the rules below:

When removing the old motor, be sure to turn it. If this is not done, part of its fastening may break and get stuck in the torpedo, or more precisely, in the mounting bracket. And getting to the stuck fragment will not be so easy.
When tightening the mounting screws with a Phillips screwdriver, you should not use too much force: they are small, so the threads in their sockets can easily be stripped.

As practice shows, replacing an engine is not particularly difficult even for a novice car enthusiast if he has held a wrench and a screwdriver in his hands at least once in his life. The whole procedure takes 40–50 minutes maximum. The main thing is not to overdo it with tightening the fasteners, and everything will be fine.

How to step by step remove the heater motor on a VAZ-2109

Many owners of the VAZ-2109 and other domestic cars have encountered a situation where turning on the stove was accompanied by a high-pitched squealing sound or an unpleasant creaking sound.
To eliminate them, you can, of course, use lubricant, but, as practice shows, such elimination of the problem is not enough for a long time, and after a while the unpleasant sounds appear again. In this case, only replacing the fan, or more precisely, the heater motor, will help. For car enthusiasts who decided to remove the heater motor on their own for the first time on a VAZ-2109, after lifting the hood, the question immediately arises: how can it be removed and pulled out of this place? In fact, everything is much simpler than it seems at first glance, but you will have to tinker for half an hour.

In order to remove the stove motor, you will need a Phillips screwdriver, a 10mm socket and a handle with a ratchet. Below is everything step by step:

First of all, you need to open the hood, find the place where the stove is located, and unscrew the 5 bolts of the plastic cover. After unscrewing, remove and place near the car. In order not to look for new bolts during the assembly process, instead of those lost during dismantling, it is advisable to initially prepare a small box for them.
The next step is to carefully remove the rubber sealing gasket of the hood, as it will interfere with the removal of the protective casing, under which the VAZ-2109 heater motor is located. After completing these steps, access to the motor will be completely open.
Next you need to unscrew the two bolts that hold the heater motor. They are located on the sides of it. They also need to be put in a safe place.
Now let's move on to something more complex. On the VAZ-2109, the wiring going to the heater is soldered directly, and on the other side it is connected to the general wiring located in the car interior. Therefore, you will have to tinker a little. You need to find the positive wire plug and disconnect it. It is located in the passenger compartment under the panel on the driver's side.
Let's move on to finding the negative wire. Its location is also under the panel on the driver's side, but there is a certain problem, since it is secured with a nut. Therefore, you need to feel it with your hand and use a 10mm socket and a ratchet to unscrew it. The wires can be immediately pushed out without leaving the cabin, through the rubber seal in the body.
We return to the stove motor and try to pull it out of its seat, changing the angle. We find the most acceptable position and carefully move it to the right side as the car moves almost all the way.
When the motor is at the point of maximum expansion of the engine compartment, we finally pull it out of the car body.
After the stove motor is in good hands, use a screwdriver to pry up the casing seal and separate it into pieces.
We release the mounting brackets and remove the cover from the motor and take it out along with the wheel.

In order not to disturb the balancing, it is not advisable to remove the wheel from the motor shaft.

Assembling and replacing the stove motor is carried out in the reverse order. There is no need to try to repair the motor or try to replace it with something else, this can lead to failure of the entire heating system of the “nine”. As a last resort, you can install a part from another, similar car model, but it is better to purchase a new device.

How to replace the VAZ-2114 stove motor with your own hands

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 further travel by car at all. It’s one thing when you came to the garage, noticed a non-working heater and refused to move further in the car during the breakdown, but if this breakdown caught you on the road, the nearest service center is far away, and it is not possible to drive a car with a non-working interior heater, because the windshield becomes covered with frost and further movement becomes dangerous. Then the only option left is to either transport the car using a tow truck, or try to fix it yourself.

How to remove the device

The dismantling procedure is not as difficult as it seems. Although you will definitely have to spend time on it. Let's look at step-by-step instructions that will help you quickly remove the fan and fix any system malfunction.

Open the hood and remove the plastic trim. To do this, you need to twist its fasteners and then carefully remove it.
Then it’s time for the rubber seal on the hood. It should also be removed.
The heater housing is visible in front of you - the last obstacle before your cherished goal. It also needs to be removed. When removing it, be careful not to damage it.
Now you can already see the fan and the fasteners on which it is held. The first step before removing the device is to tighten the two bolts.
Return to the car interior and locate the positive power cable under the dashboard. Turn it off. Next in line will be the negative cable. It is secured with a special nut that must be twisted.

There are no more obstacles left. Now you need to remove the fan. Please note that this is done on the right side and at a slight angle. As you can see, there is nothing complicated in this procedure. It just takes a little time and care. If any points remain unclear to you, you can use the video instructions on our website.

Diagnostics

The primary task is to identify the cause of the breakdown and assess your own capabilities in a specific situation.

Let's start with something simple and move on to something 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, all of the above devices refuse to work. If it is working, we move further along the chain.
Turn on the car's ignition and switch the speed control to positions 1, 2, 3 in order. If the fan does not work in any of these positions, we move on.
If the heater motor turns on after the car engine has warmed up, the problem is a faulty ignition relay. Solved by replacing the relay.
If the heater motor refuses to work in any mode, there remains one malfunction - the heater motor itself.

The process of dismantling the fan motor

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

Where is the heater fan located and how to remove it?

Practical training on dismantling the VAZ 2114 heater begins with determining its location. If you follow the sound, the heater along with the fan can be found under the windshield in the space under the hood. In general, the factory says that you can dismantle the engine without removing the heater. For this purpose, the following technique has been developed, which we are happy to share:

It is better to remove the terminal from the battery.
Now we go into the interior and find the terminal connector for the heater motor power wire.
You need to try to unscrew the lower nut that secures the heater housing to the engine shield. This is necessary in order to disconnect the ground wire of the electric motor.
Now you need to somehow get to the engine itself. To do this, so as not to remove the entire heater, you can try to unscrew the two screws that are visible under the hood on the fan casing.
The only way to get to the motor is to remove the casing.
The two fan housing screws are now visible. They need to be unscrewed.
But this is not enough, because the fan will not fit into the gap between the engine shield and the air intake grille. It will also have to be removed. To do this, you need to unscrew five more bolts.
But the most difficult thing is to free the fan along with the case. Here, only ingenuity, patience and Buddhism can help solve this problem. . In fact, this is perhaps the most difficult task.

Further repairs and disassembly should be carried out only if there is no way to find a new engine assembled with a fan, and only if no one is going to remove the turbine from the shaft, otherwise the entire assembly will have to be thrown away, since the factory alignment cannot be achieved under any circumstances. Verified.

How to remove the heater fan on a VAZ-2114

If none of the above brings success, then we will remove the electric motor of the stove; for this you will need a screwdriver and a small set of keys.

Disconnect the terminals from the battery.
There is a positive terminal and a negative terminal located in the cabin under the dashboard; they must be disconnected.
Next, we move into the engine compartment of the VAZ-2114; the fan casing cover can be removed after unscrewing the four fastening screws.
After opening the casing, you need to unscrew the two screws that secure the fan.
Next, we unscrew the screws that secure the air intake grilles to the housing in front of the windshield. Let's take them off.
Next, we remove the electric motor of the stove, since all its fastenings have already been removed. The fan is placed on a hook located on the body - move it towards you and lift it up.
After removing the fan housing from the hook, you need to rotate it 90 degrees to remove it from the casing, or disassemble the heater housing for convenient removal.
We disconnect the motor with the impeller from the casing.
Remove the impeller from the motor.
There are several further options: either replace the electric motor with a new one, or try to bring the old one back to life (if this is appropriate, for example, by replacing the brushes. If the winding is broken or there are problems with the armature, then it is better to replace the entire motor).
Next, we collect everything in the reverse order, removing all the debris from the heater shaft.

New and old heater motor

After the work has been done, we enjoy the rustling of the heater motor, the warmth and comfort of our car. These simple tips will help you save money and continue your planned trip.

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.
