Check the wiring harness in the door hinge area by pulling back the 
rubber accordion hose away from the jamb side.
The vacuum line goes through there, cracks and raises ten kinds of hell, 
but you can usually hear them leaking (sucking vacuum).
The signal wires also get cracked, and can be shorting across to another 
bare one, causing all sorts of weird things- turn on the stereo, the 
doors lock etc.  There is a live wire in there too to the window and 
door switches- it shorts across bare exposed wires and freaks out things 
if so.
When there wer issues with the 97 passat, the right rear door had NO 
wires that were not mangled.
