Both my back power windows stopped working. The main switch on the drivers side does not pull down or push up the windows, nor do the individual switches on the back passengers window work at all either. I was wondering should I purchase a new motor and bracket for both AND a new master switch and new switches for the back? Or, just buy new switches without the brackets and motors? I checked the fuses and changed them and that wasn't the problem. Any help would be greatly appreciated. Thanks a bunch.
