Which fuse is responsible for the radiator fan?


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.

How to check the fan

If everything is fine with the circuit, the problem is in the fan. Here the situation is aggravated by the fact that this is the most expensive part of the cooling system, so it is recommended to repair it.

Most often the problem manifests itself in the electric motor, i.e. in the heart of the fan. To check, connect it directly to the battery: plus to plus, and minus to minus. If it doesn't work, it's a wake-up call. First, inspect the brushes. They must be intact and not erased.

Next comes the bearings. If you hear a crunch or crack when turning, they need to be disassembled, cleaned and lubricated. Then inspect the contact group. If there is black carbon deposits, clean it with sandpaper and a brush soaked in alcohol.

If these actions do not lead to the desired result, the only option left is to completely replace the fan. It is also recommended to replace all components of the circuit, including fuses and relays.

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.

How to check the cooling fan?

If the cooling fan does not work, you will have to find the cause of its failure. First, let's check the temperature sensor using the method used on injection engines, to which the VAZ 2114 belongs. To do this, you need to start the engine and warm it up to the temperature at which it usually operates. Then you should remove the temperature sensor connector, thereby disconnecting it from the machine’s power supply. This is done so that the controller starts the fan in emergency, constant mode. If the drive starts working, this indicates a faulty temperature sensor (thermostat), while the relays, fuses, wires and the turntable itself are in working order.

Recommendations for care and maintenance

  • Buy original fuses. Domestic or foreign, it doesn’t matter;
  • Install strictly in accordance with amperage ratings. Unacceptable with lower or higher current strength. In the first case, this will lead to damage to the module, in the second - to breakdown of the unit, which is attached to the fuse;
  • Carefully check the quality of fixation of terminals and limit switches on the board. If loose, tighten and press with pliers. A spark can cause a fire and melting occurs;
  • If moisture gets in or condensation forms inside the mounting block, remove the cover, dry it, and if necessary, blow it with a stream of compressed air.

Carry out preventive and diagnostic work in the fuse box with the battery terminals removed in order to prevent a short circuit in the circuit.

The average service life of fuses is 40 – 60 thousand km. The service life of foreign analogues is 10–15% longer. Before replacing, read the instructions and get advice from service station specialists.

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?

  1. 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.
  2. 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.

replacement

To replace a blower fan yourself, you'll need a fairly small set of tools, which include:

  • Crosshead screwdriver;
  • Hex key 8 mm;
  • 10mm socket wrench.

If you are ready, then we will begin work.

  1. Place the car on the level platform, turn on the handbrake. Just in case, you can place additional supports under the wheels of your VAZ 2114. It never hurts to take precautions.
  2. Raise the hood, disconnect the negative terminal from the battery.
  3. Using a 10 mm wrench, the fastening parts of the air filter
    are dismantled.
  4. Equipped with a screwdriver, loosen the clamp from the channel located on the mass air flow sensor. This way you can remove the corrugation. Do it.
  5. The air filter housing cover has self-tapping screws that hold it in place. They are unscrewed with a screwdriver, after which the filter component is removed from its seat.
  6. Take an 8mm wrench and use it to remove the air intake fittings, then remove the air intake.
  7. Now, with a 10 and 8 mm wrench, the mounting nuts on the fan casing are removed along the entire perimeter. In total you will find 6 nuts there.
  8. Disconnect the wire connector from your broken fan's
    .
  9. Remove the fan hood by grabbing the drive, that is, the electric motor.
  10. Armed with a 10mm wrench, you will need to remove the three mounting bolts holding the motor to the housing.
  11. Install a new fan in place of the old device.
  12. We put all the fasteners back in place, connect the connectors, and reassemble in reverse order.

WHAT TO DO IF THE ELECTRIC FAN WORKS CONSTANTLY?

Sometimes another problem arises. Many car enthusiasts are interested in why the fan on the VAZ 2114 is constantly running?

There are four possible causes of the malfunction:

  1. a short circuit has occurred in the electrical circuit;
  2. the electric fan relay has broken down;
  3. The temperature sensor needs to be replaced;
  4. The electronic unit is broken.

Most often, the fan starts to work continuously as a result of a shorted wire. The electrical circuit remains on regardless of the signals from the temperature sensor and relay.

To troubleshoot the problem, you need to ring each wire and find the fusion point. Sometimes it is noticeable even upon visual inspection.

If ringing does not help identify the malfunction, you need to check and replace the fan relay. The cost of the device is low. Therefore, for diagnostics it is easier to buy a new relay and install it in place of the old one.

If this does not help, then you need to check the operation of the temperature sensor. After all, it is he who is responsible for turning on and off the electric motor of the VAZ 2114 fan.

If all other elements of the system are working properly, you need to check the electronic module. It rarely fails. If the problem still occurs there, you will have to perform a complete error reset. Sometimes only a complete flashing helps. Not everyone can do this work on their own. Therefore, it is better to seek help from a car service center.

It would also be useful to install a button to force the fan to start and turn off on the VAZ 2114.

This solution can be very useful if the breakdown occurs somewhere on the highway far from the city. In this case, using the button on the instrument panel, you can force the fan to cool the engine.
