Hi - I have an 01 a4 2.8 quattro. I live in New England so heat at this time of the year is pretty crucial in the car. I woke up this morning to find that the climate control won't turn on, it just stays in the off position. The rear defroster won't turn on either - the light goes on but turns off as soon as you release the button. I was having trouble with the blower motor before and was planning to replace it. Would the blower motor going bad cause this to happen?

 

Probally Not. I had mine unplugged for 2 days and the rear defroster still worked and the climate control unit still lights up..

 

hmm - checked the fuses and everything looks good there. any other ideas? if it was the heater core i would imagine it would still work just cold air would come out. The off light works but when you press any other buttons nothing happens. Something electrical?

 

what a noob[:@] the off button was stuck

 

yeah i was gonna mention that. my off button gets stuck every now and then, it's a pain but i just flick it a few times. seems to do the trick

 

hahahaha.... hahahahaha.... wow thats funny

 

I never would have guessed that without seeing the ac control head. I was leaning towards the fuse. KISS always seems to work huh.
