The window motors all use reversing the power to control up/down. If the
window goes down with power the problem is the switch.

The door window motors are fun. The motor and the lifting rack all comes
out together on most of them. You have to get the window in the correct
position so the rollers can come out of the track. The you reach in and
lift the glass up and block it in place.

As i said before, no you can tear the door apart, but it is much easier to
just grind a nide hole out with a cutoff disk. then it ia easy.
