Hours after I washed my car, if that has anything to do with the problem, my windows didn't work, all 4, soon after, my turn signals stopped working, then the sunroof. The next day, my wipers didn't work, and the AC didn't blow any air, finally my sub and the amp stopped.
The thing is, the windows and the roof still open and close when I lock and unlock the car using the key in the door handle, and my blinkers work when I put the emergency lights on. Also, everything else works; hi/low beams, the stereo, the AC display turns on, the speakers work, all the interior lights works as well as the dash.
I have checked all the fuses, they are all getting power, I was adviced it's a central problem since most of these components are separate from each other.
Could it be the entire fuse box? maybe some relays? where else do these components connect or get their power from? Any help and ideas is appreciated.

 

hey i just fixed a very similar problem on my 1999 audi a4 b5 turbo. There is a relay behind the glove box. which probably became wet when you washed the car...it gets there via the pollen filter in the engine bay. I am pretty sure that will fix your windows and sunroof. As that fixed it on my car......

well to be exact i replaced 3 relays.....the one behind the glove box was one of them...but i am pretty sure it is for windows and sunroof.....the other relays were behind the panel drivers side

you will have to remove the side panel on the glove box then the glovebox itself to get to the relay.
