PERFORMANCE ORDER
1. If the delivery fan does not work, first of all, check connections of sockets in a fan chain. Check the fuse 2 on the panel of safety locks located under the dashboard. Check the relay of the delivery fan in the panel of fuses and the relay located under a cowl.
2. Define a fan relay arrangement. Remove the relay and check whether correctly it functions. If the relay is faulty, replace it.
3. Install the gear shifting lever in parking situation and put the car on the emergency brake. Install the ignition key in position of ON, without starting the engine.
4. Check how the fan works in all modes.
5. If safety locks and the relay are in the normal state, and the fan does not work, test the fan.
Connect a tester to blue and red contacts. The tester has to show at least 10 V – ignition is included, the switch of the modes of the fan is in any situation except position of OFF (Is switched off). If it not so, in a chain of the fan are malfunctions.
6. If tension moves on the fan, and it does not work, connect by means of a crossing point a black / white wire to grounding on a car body. If the fan still does not work, then it needs to be replaced. If the fan works, it means that in a chain of grounding of the fan there are malfunctions.
7. If the fan works, but not in all modes, check the resistor of the fan which is located on a fan casing (it is specified by an arrow).
8. Remove the resistor and examine it on existence of damages. Check the resistor by means of an ohmmeter. If necessary replace the resistor.
9. If the resistor functions normally, and the fan still works not in all modes, remove the heater control panel / the air conditioner. Disconnect wires from a back part of the gearshift of the fan and check switch resistance. If the switch is faulty, replace it.
