My window moter on my drivers side window seems to be working fine but the window won't go up and down. I've taken off my door panel in my 1984MB 300D european version and the teeth don't seem to grab on to the other teeth that they need to in order for the window to go up and down. Any one got any suggestion for fixing it. FYI this car is for sale in Virginia if anyone interested please call 703.938.4105 or email me at FrancoTraverso@yahoo.com.
