My 2011 silverado's windows suddenly began acting up. Worked fine one day and then the next I can not put my drivers window down. Here is what it is doing: The switch on the the drivers door will control the two rear windows and the passenger window but will not control the drivers window. The other door switches won't control their windows, only from the drivers switch. Also, the window lock button will not activate (light will not come on). I have pulled it out, wiggled all wires, even the ones from the door to the cab. I picked up a brand new master switch from the dealer and replaced. Nothing!! I am stumped. Any help would be greatly appreciated.
