My tailgate window will not work with the key. Works sweet from the dash switch, it's a pain in the rain at the store having to open the truck to hold the switch every time, any suggestions? I took the cover off the inside of the tailgate but it looks like a big disassemble project to access the lock cylinder etc??? Also, my power door locks don t work right either, the driver side lock won't operate, the switch on the drivers side works fine for the passenger side, the switch on the passenger side works fine for the passenger side, drivers side nothing. The switch on the drivers side doesn't work the drivers side lock, whats up with that?
