Well, it's about half and half. Sometimes i'll get in my car, and the power windows and sunroof will work normally. Other times i'll get in the car, press the buttons and absolutely nothing works; they won't go up or down. If they don't work, I might come back to the car 10 minutes later and it will all be fine again. Pretty haphazard. Is there like a fuse that's going bad or some type of regulator? Now that summer is here, it's not cool coming out to a baking hot car and not being able to air it out. The car is a 1995 Audi 90 CS. Thanks

 

probably a dodgy switch or ground

 

Yeah. I'd say break out teh multi-meter and start hunting... good luck!
