powerwindow only goes down.could this be the switch on the door is faulty.does anybody know which wire contact colors i have to test to see iff switch is faulty as i dont have a wiring diagram thanks.
Mate you will find it is the switch. I had a similar problem in my ss, would go up but rarely went down. I just pulled apart the switch, sprayed contact cleaner on it and presto, it works like a new one. That would be my bet mate.
