99 tahoe LT without warning, last night, while I was closing my window, it stoped half way up. when I got home I checked the switch (well I tried, its one piece...) the switch seems to be working, I then removed the door panel, the motor was very hot, I tried to remove the metal panel when the motor is mounted but without luck (it was 9:30 pm, I couldn't much..) while in there I found a broken part inside the door panel. is that part part of the window mechanism ? how can I fix my window ? I'm leaving for a road trip thursday AM early to CA so I have very little time.
