Hi all, first time posting here. I have a 2000 GT and the rear driver's side window is screwed up (probably from my 7 year old messing with it...). Can't get it to go up or down, motor seems to only move a little bit, can can hear it, but it just goes for a sec then stops. I can manually move the window, but it won't stay up without help. Do I need to replace the motor? Or could it be the guide wires? Any thoughts?
