The circuit for switching on the heater fan electric motor is the same on VAZ-2105, VAZ-2104 vehicles. It is shown in fig. 250. Electric motor 5 is turned on by a three-position switch 3. In the middle position of the switch key, power is supplied to the electric motor through an additional resistor 4 and the electric motor rotates at a reduced frequency - 2200 min-1. When the key is fully pressed, the electric motor is supplied with full supply voltage and rotates at maximum speed. Resistor 4 is fixed with two spring washers in the heater fan casing. The resistance value of the resistor is 1.5 ohms at 20°C.
Replace defective motor. The only possible repair is cleaning the collector. To disassemble the electric motor, unscrew the screws securing the cover and remove it. Then remove the lock washer from the armature shaft and remove the armature from the housing. Checking the technical condition of the electric motor and its malfunctions are similar to those described above for the windshield wiper motor. Assembling the motor is in reverse order.
