I have a problem with my 2001 ml 320. The other day my driver window stopped rolling up and down with not previous signs. the window will manually go up and down, and the window motor is functioning. I've removed the door panel and inspected the operation of the motor and gear. Everything seems to be functioning correctly, except the window won't go up or down. The motor turns the gear and stops like it should. It looks like there are some spot welds on the track that is behind the gear that have broken, but I can't tell. Im am mechaniclly knowledgeable but don't work on MB ever. Any help would be much appreciated.

Check the window switch cluster. 163's are notorious for window switch's going and you are left with a window that does not go up or down. The biggest problem is you can't replace just one switch, you have to buy the whole panels with all four switches.

I dont think it's tbe switch because like I posted above the motor functions correctly. The window just isn't connected to the motor somehow.
