I have a 68 and all of my windows work on their own switches except the driver (wing or window). I had the driver window master switch as well as the wing window switch rebuilt. The back windows roll down with this switch but not the front… wing or full. I have the wiring diagram but the wiring is different than the diagram. I can see the switches drawing power when I hit them but no movement. Any thoughts?
I would check the contacts on the drivers door plug. When I went through my car, a lot of those contacts were corroded. I scraped them with a mini screwdriver, and smashed them closed (not completely closed) to create a better contact. If you tested the new switches on the other windows and it proved to work, then the switch is the known good. You would start at the contacts for the drivers door, then work your way back. I hope that this helps.
