Rear window problem
I would open the door with the window problem and check wires in the rubber boot for any shorting.
For me one of the issue was due to the "spinning barrow" door lock. After I adjusted the barrow to it's neutral position it seems to be better for the all-window-down problem for now.
My rear window could be shorted like GTA mentioned, or the regulator is bad.
Both issues need some work still.
