A6'er here need your help | I picked up a 1990 90 quattro - - - >>>

The drivers side window and sunroof work the first day then it all stop working | can't find any fuse or relay for the windows or sunroof | I checked the Bently manual but can't find any info |

I searched the previous post - but reached the dead end. Can someone please advise where and what to look for?

Thanks and regards.

Well, a fuse or relay would most likely affect all 4 windows.

Check the switches. Not sure if the 1990 90's were culprit to the window switch problem. But the contacts inside the switch get corroded and need a little cleaning. Used to have to mess with them all the time on my 4K.

The window switch cluster is a common failure, but might not tie into the sunroof....

Post in the C5 forum, those guys are invaluable.

I had this problem on my B4 90....

On my '95 (B4) 90Q the sunroof and windows were on the same circuit. The circuit had a relay in the fuse panel area underneath the driver's knee bolster. I pulled the relay and replaced it with a "new" one and ...voila...everything worked.

Search "sunroof relay."

Again, I've never been lucky enough to own a CQ so I don't know if the wiring is the same.

Good luck,
Dave
