I got power to window motors on parts car. Unfortunatly all motors work except the one I need, i.e., the drivers side rear motor.

So how does one remove motor and regulator when motor is not functioning and window can not be lowered?

Edited:

I can not remove the safety bracket on window lifting rail with the window in the up position. If I could get that off maybe I could removewindow bracket from regulator and remove. Suggestions?
