I know this is a much discussed topic but I haven't found my particular problem described before. The passenger window on my '85 Euro spec QV used to work fine, then stopped going up (still goes down fine). I took the door apart to do the standard 308 window service desribed in detail in previous threads, and found that the motor would not go in the up direction, even with no load. A meter on the motor wires showed +12V in one switch position and -12V in the other switch position, so I ordered a new motor. Same problem with new motor. Just for kicks I swapped out the window relay with no improvement. What's going on?
