How do you fix a window on a Ford E-150 van that will not roll up?
This is probably due to the window lift motor going bad. Take
off arm rest, inside door latch and speaker grill. Now remove the
inside door panel by prying it off with a screw driver along the
perimeter. Now you can see the motor inside the door. Removeall the
attachingbolts and remopve the motor and gaerabox. Test it on a 12
volt source to be sure it is bad. If so, replace.
