2017 Silverado z71 Crew Cab

Master window switch only operates d/s front window.

Window lock button inop

mirror adjustment switch inop

Master switch does not work on P/s window or either rear windows.

I can roll up/down all windows from their own switches no problem. I can also roll them down using my key fob.


I have replaced the d/s master switch and the mirror adjustment switch. Still didn’t work. I have replaced the d/s door wiring harness, that still didn’t work. I have tested continuity from the switch connections to the door jam all the wires tested good. I’m at a loss from here. If someone could point me in the right direction or perhaps if someone had a wiring diagram, I would really like my windows to work. I appreciate any help or insight you may have.
