The cooling of a car engine must always be efficient and effective. The VAZ 2114 is equipped with a liquid-cooled engine. Such a system is quite efficient and reliable, and cooling in it occurs due to the flow of liquid through a cooling radiator, which is cooled by a counter flow of air.
As you can see, such a system only works when the car is moving, but as soon as it stops, the radiator stops cooling, which leads to heating of the car engine. For such cases, the VAZ 2114, as well as other cars, is equipped with a special, powerful fan capable of creating an air flow no less than the oncoming air flow.
Quite often, this part on the VAZ 2114 refuses to work, which can lead to the engine boiling, which can cause serious damage to the engine.
This article talks about the engine cooling fan on the VAZ 2114, namely its purpose, causes of failure, the sensor that turns on the fan, methods of replacement and testing.
Where are the fuses on Kalina and why are they needed?
Every vehicle is equipped with a fuse box. The first generation “Kalina” is equipped with 3 such devices: installation, control and additional. The second generation model, or as it is also called “Kalina 2”, is equipped with 2 blocks.
These elements are necessary not only to protect all vehicle electronics from combustion, but also prevent the occurrence of fire, because In the event of a short circuit, they take on the entire load. In this case, the fuse itself fails, thereby stopping the flow of current to the electrical appliance.
What is a relay for?
The windshield wiper relay is designated K2. Its stable operation ensures the supply of a cleaning liquid composition to the front glass. And without this, there will be no normal activity of janitors.
Failure of the front window wipers is a good reason to check this relay. In addition, you should check the operation of the windshield washer motor and its pumping device. The reason may be that the fluid level is insufficient, so the washer fluid tank should also be checked.
The additional relay is designated K6.
Fuse types
Fuses are classified into cylindrical and blade. The first ones were used in the operation of old-style Russian cars. Knife-type elements are considered safer, more convenient and are used in all Lada Kalina cars.
Fuses also differ in the rated current indicated on the housing and in size. In addition, each value of the maximum permissible current has its own color, which also makes it possible to distinguish fuses without much difficulty.
Mounting block
Located under the instrument panel for controlling dimensions and headlights, on the driver's side to the left of the steering wheel. In this block, Kalina fuses are responsible for the safety of almost all installed electrical appliances. The location of the mounting block for car fuses of generations 1 and 2 is the same, but its diagram is different.
A breakdown of the Kalina fuses of the 1st and 2nd generations is presented below.
Rear window wiper
By windshield wiper we meant the windshield wiper. This applies to all of the above models, but the 2112 hatchback and 2111 estate also have a rear window wiper. It is located on the tailgate. The composition includes a motor and a brush equipped with a lever.
Control block
On the 1st generation Kalina it is installed under a cover in the center console. The fuses in this unit protect the most basic electronics. There is also a connector for injector diagnostics. On a 2nd generation car the unit is located under the hood, in the engine compartment.
COOLING FAN DIAGNOSTICS
If signals appear on the dashboard indicating that the permissible temperature level in the cooling system has been exceeded, this may indicate that the fan on the VAZ 2114 is not working. The main symptom of the malfunction is that the mechanism does not start even with a significant increase in temperature. It is urgent to turn off the engine to prevent its elements from overheating.
The engine should not be operated with a faulty electric cooling fan. This may damage the cylinder head.
If the cooling fan on a VAZ 2114 does not work, the following malfunctions may be the cause of the breakdown:
- The fan switch sensor on a VAZ 2114 has failed.
- Lack of contact at the sensor connector.
- The wiring has broken.
- Electric fan relay faulty.
- The fuse has blown.
- Damage to the device's electric motor drive.
Unplug the device. Connect it to the battery terminal. Maintaining polarity. If a direct connection to an energy source starts the electric motor, then the drive is working. There may be problems with the wiring, the fuse, or the temperature sensor.
Now it’s time to diagnose the fuse. You don't even have to open the plastic box to do this. If the relay malfunctions, the horn stops working at the same time as the fan. Therefore, if you notice the loss of the sound signal, it means that the fuse has definitely blown. You can find it in the engine compartment in a small plastic box. We release the cover, pressed by two latches, take out the burnt fuse with tweezers and replace it with a new one.
But diagnosing a relay is quite difficult. Especially for those who are exclusively “you” with auto electrics. To check functionality, the easiest way is to find a working relay and temporarily install it. If, after installing a new device, the fan begins to work properly, then it is time to replace the old one.
To diagnose the temperature sensor that supplies a signal to the radiator, you need to disconnect the connector from the sensor and start the ignition. The emergency mode will start, in which the electric fan will start blowing. If the fan starts late when the connector is disconnected, the sensor is most likely faulty. Replacing it will take no more than five minutes. You just need to unscrew two bolts using a Phillips screwdriver and install a new device in its place.
Even if a malfunction has occurred in the VAZ 2114 fan itself, this does not mean that it is time to change it. Sometimes you can simply replace a damaged bearing or brushes. But if the electric motor is faulty, it is much easier to purchase a new mechanism.

Do the wipers turn on themselves on the VAZ 2114? Solution
Water and dirt accumulate on the windshield during rain, snow, and dust flows. To get rid of this, the design of the car provides for the presence of special elements - wipers.
Circuit breakers
Inside the cabin, at the driver's fingertips, there is a windshield wiper speed control . Brushes can have different sizes and function in several modes.
If we talk about windshield wipers on the VAZ 2114, they have four operating modes:
- With interruptions;
- At first speed;
- At second speed;
- Together with washer.
There are two modes on the rear window:
- With washer;
- No washer.
Dimensions
In fact, the size of the wipers on the VAZ 2114 plays a fairly large role in the quality and efficiency of glass cleaning.
Windshield wiper wiring diagram
Small brushes are also not good, because then the cleaning area is reduced and not the entire glass surface is cleaned, which would provide the required visibility for the driver.
Then what should be the size of these same brushes in the case of the “fourteenth” model?
- The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The brush on the driver's side can be replaced with an element 53 centimeters long, but on the passenger's side it is important to leave 51 cm. Otherwise, a strip of cleaned water will remain on the glass between the driver and passenger.
- There is also a cleaner on the rear window of the VAZ 2114. But in this case, the size of the element is 30 centimeters. It is possible to install the wiper at 33 centimeters, which allows it to fit perfectly into the dimensions of the rear window. Some even install components at 40 centimeters, but in this case you will definitely have to increase the wiper stroke limit. To do this, remove the motor, shift the teeth by several units and put it in place.
Common problems
It is not uncommon for car owners to encounter a situation where the wipers on a VAZ 2114 do not work properly. The causes of the problems may be different, so you should carefully examine the breakdown, and then take appropriate action.
Typical faults include:
- They work constantly;
- The windshield wipers may operate on their own, even though the driver has not turned anything on or pressed anything;
- May work too slowly;
- Spontaneous switching occurs.
Replacing the motor
In practice, replacing wipers on a VAZ 2114 may be necessary in several cases. The most common is the failure of the gear motor.
There are different reasons:
- The brushes constantly work, the shutdown relay does not work;
- Turning on the regulator does not allow the wipers to start;
- Sometimes the windshield wipers simply do not turn off when the corresponding buttons are pressed, etc.
