A few weeks back I accidentally opened the drivers side rear window using the drivers door master control. I pressed the up button and the window went down more, pressed up again and it went all the way down and stayed down, neither the front or rear passenger switch would do anything. My local mechanic got the window up and found that with the master control out of the loop the rear switch operated the window (so motor OK). He thought the master swtich was faulty. I purchased a new master control switch, fitted it and while the front windows work perfectly, the rear passenger side window clicks and doesn't move, the rear drives passenger window goes down but not up (even when pressing the up button it only goes down!) - pressing the swtich to isolate the rear windows allow the rear door switches to operate their respective windows. My other observation is that closing the drivers door can trigger the locking central locking - i.e. it makes they same sound as pressing the unlock button on the remote control with the car unlocked. I doubt that the new switch is faulty as it seems to have the same problems as the old one. My theory is the wiring loom in the drivers door, perhaps where it folds/unfolds as the door opens, has seen better days. Has anybody seen this fault before, if so what was the cause? All clues gratefully rec'd. I am also wondering what the part number(s) are for the drivers door wiring loom and ideas on cost. Online research has been unsucessful so far;I hate going to the main stealer unprepared!
