My drivers side power window works on my 4 Door 250S -
108.012 12 048400. However, the window ''sags" down now, and won't move. In addition, I lowered the passenger side window, and it goes down, but not up. Can anyone give me some ideas where to start? Thank you.

Come on, somebody knows something about power windows!! please?? Give you a ride in my new '67 benz : )

Sounds like you have an electrical disconnect.

At this point, you need to pull the door panels and apply 12V to the motors and see if they work.

See archives or manual to pull door panels.

Thank you Jim!! I thought maybe a ground wire because the car sat for so long I have a few ground wires that were dirty.
