I own a Benz 1989 300e and the driver side and rear passenger window on the right are stuck open! I cant seem to figure why though. i started switching switches around to see if i can manage to get them working but nothing. the two windows are stuck open. the switches don't work at all! I am going to buy a new switch online and see if that changes anything but in the mean time i have to get these windows up. this leave for one option. the door panel must come off. any help would be much appreciated.
