What I found was that the two wires switch polarity depending upon the direction of the switch near the handbrake. That would appear to be a relay that does that. Going back to basics, if I spike the other wire and connect that to ground I can get the window to move in one direction. That would suggest a bad ground - either at the relay or the switch itself. The relay is a little too complicated to my simple understanding ... And I went through a few fuses testing some theories about the ground at that point. ... > Is there a good ground at the switch connector on the incoming line > (basically the wire that connects the switch to ground permanently)? > What about on the outgoing line (the wire from the switch to the motor > terminal)? According to the wiring diagram, there are three grounds. One must be permanent and the other two depending on the polarity, presumably. So, it must be the switch that is switching polarity, rather than the relay. I must say, since I've got the window up I've not looked at it again. I'll do some tests on the switch - I had hoped it was an easy "oh yeah, just re-do the ground here" kind of thing ... Grrr! As you say, I'm not keen to start pulling the car apart without asking a few people first :) > I wouldn't remove the centre console just yet (but that's not ahuge job > anyway) - it could be the switch or the switch connector. >> What is the air speed velocity of a sparrow? > ? Can I have some of what you're having? It's called Akvavit :) Sweden drew tonight with Denmark, so I celebrated with both nations' national drink :) This one is Danish, but I'm about to hit the Swedish variety in a minute ... Mmm! Roll on 1AM so I can watch the game! Thanks for your reply - much appreciated (as always). Paul
