2016 GMC Sierra 1500 Sliding Rear Window

[wolhausen]

I cant figure out why my rear window quit working. I have checked the fuse panel and I think my fuses are label incorrectly and or I am missing fuses. I checked the switch in the ceiling and only 1 of the wires going in has power to it no matter what way the switch is pressed. I also checked the black plug going into the rear window motor and there doesn’t seem to be power going to it. Can you tell me if the switch is working correctly, is that how it is supposed to work? Also I took out the fuse that says is for the rear window but there is still power going to the switch when I remove that fuse (see red arrow in photos) the next thing I was going to look for is the relay and replace the switch. I would think the switch would have power coming out of it when the switch is pressed or pulled and I don’t have anything just the power going in on the far right wire.

 

I hope that makes sense.
