This all started a few days ago. Started the truck in the morning and all 4 windows rolled down randomly. I was able to get only the passenger side up. Got to work. Turned the truck on and off a few times and then could roll down the rest of the windows at each door, not by the main switch. I took the switch off and cleaned it thinking it could be a bad contact or something. It didn't help. Everytime I start the truck up all the windows go down except the drivers door which does nothing. When I hit the drivers switch the switch actually makes a click sound. The switch is pricey so I got my buddy that's runs a scrap yard to let me try one to see if that's what I needed. I plugged in the new switch and the drivers window went up a few inches then quit. Same issues. So I get home take the drivers door off to get to the window motor. Jumped it with 12 volts to get it to go up.

So I just dont know where to go to next. All windows are going down so maybe a short is causing this since cars switch off the ground? I know the drivers motor is ok, the switch is ok, should I look for a relay or something? I got a multimeter and know the basics just dont know where to look next. Any help would be greatly appreciated.

In my '11 the Body Control Module and a window control driver operate the windows. I would try cleaning the BCM connectors with a electrical contact cleaner as a simple first step. Possible communication issue between modules, advance scan may pick that up with U codes being set since all of them go down on the start up power drop. May even be a grounding issue.
Really need a schematic to fully check it out. I use alldatadiy.com for it's full shop manual that has diagnostics and diagrams.
