I have a 2012 chevy silverado 1500 the drivers side power window stopped working. I have replaced the master switch twice in case the first ine was bad, replaced new window and regulator and replaced circuit breaker thats behind the fuse box inside the truck and still no luck. Looking for help.of what else I can check.

 

Regulator is bad will cause the window to not stay up. Bad motor?

 

i have replaced the regulator and the motor already and if i apply direct power to the motor it works.

 

Check for a broken wire at the hinge side of the door. Flexing can break wire but leave wire insulation in tact, so it looks OK. You'll probably need a voltage tester and a wiring diagram.

 

okay that sounds like its viable, i will check and let you know.
thanks
