I have an ML320 1999 and the driver side window switch is bad. The window switch controls the downward motion but when I lift up on the switch nothing happens (not even any light dimming). If I depress the switch again (with the window in the open position) there is a dimming of the lights so I know there is power to the switch and window. It appears the switch contact(s) to allow the window to go back up are bad.
We just got 18 inches of snow here in New England and this causes a bit of a problem!
I took out the console box and disconected the electrical wiring plug for the window sitches on the driver side. There are 7 wires into this plug. If I can figure out which one, or two or three, go to the driver window I can try and short these together so as to make the window go back up - then I can take the car in for repairs. I can't determine which wires to use though. I've been tryting to short out two wires but nothing happens which leads me to believe I probably need to work with three wires.
Any ideas on which wires/contacts in the plug I could short or contact together to get the window back up? The wire harness/plug seems to supply power and control both front/back driver side windows as well as the master lock/unlock switch. There are two white wires in the harness of 7 total.
Thanks. Walter
