I have a 2001 Audi A4 that has a possessed climate control system. The fan speed will raise and lower all on its own no matter what I do to it. It acts like the automatic mode is on (even though it is turned off). I can briefly over ride it by adjusting the fan speed manually, but within a few seconds it will raise or lower it again to whatever it feels like. Any help or ideas would be great, thanks.
