Contents: Fan motor ⇓ Pre-resistors ⇓
Attention! If the fan does not work only on one stage, as a rule, the pre-resistor is faulty. In this case, replace all pre-resistors.
Remove the glove compartment, see Chapter Body, car painting, car care, Chapter Instrument panel/middle console.
Fan motor
1. Disconnect the plug from the fan motor.
2. Apply battery voltage (12V) to the terminals using auxiliary cables a (+/ plus) and b (-/ minus).
3. The motor should start working, otherwise replace the motor.
Pre-resistors
1. Disconnect the resistor board plug.
2. Check the following terminals for current flow using an ohmmeter: a - b; a — c; a — d. If in at least one case the absence of current flow is detected, the pre-resistors should be replaced. The values of individual resistances are in the range from 0.5 Ohm to 1.5 Ohm.
