I have a 1991 W124 esate, that has been sitting for some time.
The front passenger (UK model) window motor is permanetly running inthe down direction, I have checked the wires in the door and they are permanently live. I have removed the console switch, but this has made no difference and checked the relay under the bonnet, which seems fine as the other three windows and sunroof operate correctly. As this is a permanently live circuit I am assuming it could be an earthing problem, any suggestions?
