I got a 1983 280se all back and driver windows do not work, only the front on the passenger side. I was wondering if it could be a switch problem and not the window motor since there is no sound coming out of the doors when you hit the windows switch? also, i would like to change the panel where the window switches are because the wood looks deteriorated, any instructions on that? any suggestions will be of great help, this is the first time i put myself up to fixing a car so i will appreciate input. Thanks
