Okay. Driver's side master power window switch works on all windows expect my passenger side window. The passenger side window switch works and the window moves up and down without any issues.

I have a 12v reading on wires from the drives side switch and a 10v reading from the passenger side terminal where the driver's side wires link into the passenger side terminal. The wires look clean, no breaks and I'm at a lost for words on why in the hell the window won't move from the driver's side master switch.

Any suggestions????? Thanks!!!

Buy a new master switch. Amazon has the Doorman replacements.
Or take the switch apart and put a tiny piece if tin foil on the contacts and see if that works. It worked for me for a few months when the drivers window wouldn't work then I just got a new switch.

 

Exact same problem in my truck. Mine was not the switch, but the wiring between the passenger door and A pillar. If I opened the passenger door, I could control the passenger window from the driver master switch. Close that door and only the switch on that door works. I still have to get in there, pull back the boot, and repair the wire.

 

I pulled back the boot on both doors and the wires looked alright... I'll keep looking, what is crazy is that when I measure the volts it still is receiving 11v from the drivers side switch...

Thank you for your response!!!
