Hi Just purchased a 85 300d with 220,000 miles on it in good shape.
I love it, I guess moved to the dark side, selling my 97 320. Never really liked that car.

Anyway, drivers window, started not going up or waited, had a delay, before it reacted to the console switch.

Then it would not go up at all from the switch. went down perfectly.
So last Saturday, took the door panel off wiring seemed intact.

Hit the motor with a mallet, went back to this delayed reaction going up.
Instantaneus going down. Worked a couple of times and quit going up again.

So question, anyway of manually running it up?
What do you think it is? Gut says its a limit switch? Is this part of the motor assembly? Right rear window also doesnt stop automaticlly when it gets to the top. keeps running if I hold the switch down, so same thing kinda?

Is this just replace the motor or are there somethings I can check. I'm comfortable with a volt ohm meter if that helps.

Probably have a bunch of diesel questions later, but I'm loving it for now..

Thanks
George
