GENERAL INFORMATION

Check of the switch of the fan of a heater on models from 1990 to 1994



Check of the switch of the fan of a heater on models since 1995


Prevention

On some models the safety airbag is installed. Therefore it is necessary to remove a weight wire from the accumulator and to wait at least one minute before work about the sensor of collision or the dashboard to avoid casual expansion of the airbag of safety.


Control

PERFORMANCE ORDER
1. Install the gear shifting lever in neutral situation, tighten the parking brake and include ignition, without starting the engine.
2. Install the air stream distributor in the situation FLOOR, and the fan speed switch in the situation HI, and determine by noise of the fan, whether the heater fan works.
3. Disconnect the electric socket from the heater fan engine and, having included ignition, check that on contacts of the socket there is tension. If tension is absent, means the relay of the engine of the fan or an electric chain of the engine of the fan is faulty.
4. If tension is present, connect the electric socket of the engine of the fan.
5. If the fan engine still does not work, means either the engine or an electric chain of grounding is faulty. For check to the connected socket connect the closing wire to a wire, black with a yellow strip, and connect other end of the closing wire to the mass of the car.
6. If the fan engine still does not work, so the fan engine is faulty.
7. If the fan works only in one or in several provisions, remove the switch of the fan and check a condition of contacts of the switch in various provisions of the switch.
8. If the engine of the fan works only at one, highest speed, check serviceability of the resistor of the engine of the fan located under the dashboard from the passenger near the fan engine.
9. Disconnect the electric socket from the resistor of the engine of the fan and take the resistor from a casing. Using an ohmmeter, check that there is resistance between all contacts (on a photo) the fan engine resistor socket.
10. If resistance between two any contacts is absent, replace the fan resistor.
