2015 GMC Sierra SLT passenger window not going up or down, mirror works but wont fold, any help would be awesome

Cesar1833 · March 12

So quick history truck is in great shape, I jumped a friend's car and noticed that the passenger window wouldnt go up/down no clicks nothing. the passenger mirror wont fold but the signal works in it and the mirror can be adjusted but if i touch the window control then the mirror wont work at all. I checked all the fuses on both sides with a fuse checker all were fine. am i missing something? a relay? perhaps the motor died? any suggestions would be awesome!

Are you using the window switch on the passenger door or master switch on drivers door?

What about the actual wiring that comes from the body into the door? Maybe the part of the wiring got nicked and is shorting out? Or one or more of the wires actually broke? And sometimes you can't tell just by looking as the insulation can hide the breaks.

So I tried the passenger switch and the drivers side switch neither worked and even hooked up a code reader that allows you to directly send the command from the tablet and nothing, it makes me wonder if the motor got fried when i jumped the friends car? just wondering if there is a relay im missing somewhere? my only other option is getting a new motor for the door and see if everything else goes back to normal. thank you for the suggestions!

Dumb question, have you manually folded the mirror by hand to see if that "resets" it? Or listened to the mirror when trying to fold it to see if you hear anything working, by trying the switch on the driver's door panel with the passenger's side window down?
