We have a car in our shop right now in which the drivers window works fine. The passenger window only works from the passenger switch. The passenger rear window works from the drivers switch and the switch on that door. The drivers rear window will only roll up from the rear switch but not down and does nothing from the drivers switch. We took out the drivers switch and replaced it but it does the same thing, also we took the rear passenger switch and tryed it on the other two windows that wernt working but that didnt fix the problem either. Any ideas on what the hell could be wrong? Thanks in advance.
