For some reason my passenger rear window will not roll down. Not from the drivers controls or the rear seat itself. Any ideas. That is the only window.... thanks!!

Try window reset:

I tried that but the window doesnt roll down at all for me to reset it. I tried holding the button up for 60 seconds and then down for 60 seconds and nothing worked. is there any other ways???

try disconnecting your battery and redoing the reset.

Check the fuse?

My first thought is a window motor issue in that door. However, I've seen cars that had the drivers door master switch go bad and kill the circuit to the rear window as well. If able the best thing to do is remove the rear door panel and check for power at the motor while someone operates the switches. If nothing there, next check for power at the switches.

Cheers

might be window regulars... never heard of it happen on a GS yet but it could happen... happened to my BMW and G35 too..
