1994 Audi 90 - Heater Fan Not Working
My fathers car will not engage the blower motor when he turns on the heater; it does not work on any of the speeds. What causes this? Blower motor resistor? Blower motor? Climate control unit? Any input would be greatly appreciated.

Automatic climate control (digital). The display turns on, but it does not engage fan. The unit responds and displays correctly, but it will not turn the fan on when you increase the fan speeds.

I have read this page: http://www.20v.org/climate.htm, but there is nothing there that describes the fan not engaging. I appreciate your help.

Have you checked the fan
to see if it still works?
Fuses ?
Loose wires?
Have you at least removed the control unit to make sure the wires are attached?
Do you have the wiring diagram for the unit ?
You should be able to take the unit out and see if you can cross the wires at the plugs to see if that makes the fan come on.
I'll look for the wiring diagram but it seems to me that I found it online.
good luck
