2005 Denali door electronics not working

[Kingfish585]

Hello all, I have a 2005 Denali I recently picked up and noticed the passenger side rear door locks and window motor do not work at all. All the other windows work flawlessly except that one. When I push down on the switch from the driver controls, I hear a small click noise like something is wanting to work but isent getting enough power or something. Any ideas? ive checked the fuses too.

I haven't tried a voltage meter test in the motor yet but have to see if the door was getting any power at all. I noticed a new wiring harness the goes between the door and the door sil, so many someone's had this issue too.

Maybe an issue in the window motor or regulator? I believe the locks are run in the same mechanism as the latch.
