So I live in Chicago,IL & we are getting temps around 15-20 now (finally cold weather)

Well here's my problem... I drive a 1999.5 and for some reason my "rear defrostisting" is not working properly. The light on the CLimate control lights up--- but I drove from home to work today...and the whole way NOTHING DEFROSTED!

Any ideas? Would the light still go on if a fuse was blwon?

 

I had this problem for one day when it got to 7* (I also live near Chicago and have a 99.5 A4tqm) The light goes on on the defroster for a few sec then shuts off every time you press it, at the same time I had weird characters on my radio and the station text was displaying improperly. Although it went away on its own next time I started the car, I assume because it got a bit warmer that day... I really am not sure what to tell you other then it may go away on its own like mine did...

 

although the defog light is on there obviously isn't any voltage to the rear window check the wires on the rear window and fuses

 

I was told my a friend that it could be "contacts" aka the LINES in the back and they have kits where u can reconnect them.

and "Draw" lines back in place.
