2007 Chevy Silverado window problem

15 Nov 2019 •
I have a 2008 Chevy Silverado 1500 (newer body style). The passenger window is acting up. It will roll down from both the drivers side master switch and the passenger side switch, but not back up. Occasionally, after quite a while, if I rev up the engine while continuously trying the window switch, it will go up. Does this sound like the motor? Or two bad switches (driver master and passenger)? Relay? Please help. Thanx.

I got fault code B0091 00 when scanning the controls on my 2009 Silverado 3500hd. I replaced the front impact sensor but still get the same code and cannot reset with a Aute l AL619. What would be the next step?
