I installed my new OEM upgrade speakers yesterday and when I tried to put the rear, drivers side window down it wouldn't work. I tried both the main switch and the switch on the back door and neither would make it go down. I took the panel off the driver door again and checked to make sure no wires came loose it all looked okay.
If something was disconnect in the drivers door would that prevent the switch on the door in question from working? I don't know for sure if the window would go down prior to me doing the speakers because it hasn't warmed up until now so I had no need to put it down. FWIW the other 3 windows work fine.
