My 90 GLI is having a myriad of electrical/lighting problems, I really don't know where to begin. Do you think it unwise to take it into the local vw shop? They are very reputable but is it likely to take hours of diagnostics?
Here's a short list of whats going wacko jacko:
right low beam is in and out randomly
rear tail lights in and out (brake lights work though)
right power recaro is out
all window regulators are in and out.

Sounds like you have a bad grounding problem.

Electrical problems like the ones you describe are technically easy to diagnose.
You can start to do some stuff yourself...such as check all your grounds, clean them, sand them down...check connections. Sometimes dirty conectors make for faulty connections. I say try and do it yourself..not hard at all. http://****************.com/smile/emthup.gif

window regulators in and out? as in sometimes they go sometimes they don't?
if that's the case ditto, things going in and out is a bad connection, start cleaning connections.

Go to the fuse block and pull it down out of the hangers. Check that all the individual plugs on the back are secured snugly in place and that the slide lock on the right hand side of the fuse panel is closed. Being a CE2 car, these circuits are all seperate that you have described so it is likely as the others have stated being a power or ground problem for the fuse panel or battery. The electrical systems on the ce2 cars are much simpler than you may think and are very easy to service if you are familiar with vehicle wiring at all. If the ground and power connections are all verified as good, you will have to trace down the individual item problems which may become expensive if you have a shop do it.
