| 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. |
