Interpretation of fuses and relays of injection models
The main electrical fuse module 2114-3722010-60 is located under the front engine compartment. This arrangement allows for quick access to all electrical systems of the car.
Block location
The power supply circuit of the injection system is protected by a fuse-link made of wire with a conductor of reduced cross-section (1 mm2). The battery charging circuit, the engine starting circuit, and the “generator - ignition switch - mounting block” circuit are not protected by fuses.

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.
If there is a problem with the electrical circuit of the cooling system, the fan will not start. There are several reasons why it does not turn on:
- Electric drive malfunctions;
- One or both fuses have blown;
- The cooling fan relay has failed;
- There is a break in the electrical wiring;
- The expansion tank plug is damaged.
Electric drive elements include an electric motor. This is the main fan assembly. It is checked by direct connection to the battery. If it does not work, you should check the motor brush mechanism, bearings, and contacts. These items can be replaced or repaired. If the problem is in the winding, then the entire motor, or even the fan itself, should be replaced. The drive belt often breaks and requires replacement. If it turns out that the motor and drive system are in order, we continue to check further.
Another element that affects the operation of the engine cooling system is the temperature sensor. If the sensor gives incorrect readings, this may cause the fan to turn on earlier or later. A delay in turning it on leads to overheating of the engine. One of the reasons may be that the sensor does not match the climate in which it is used. Then it is advisable to replace it.
Fan problems also include reverse rotation, when the blades drive air inward. This happens if the motor poles are connected in reverse. Video: the cooling radiator on a VAZ 2114 does not turn on - what to do?
