The driver side power window motor on my 93 Ford Aerostar (171,000 miles) has gone bad. I know it's the motor or regulator gearing and not the switch or wiring because when I put a good 12V and ground directly to the motor wires inside the door panel, the motor still won't turn in either direction. Fortunately, it went bad with the window fully raised.
I've removed the door panel and unhooked the motor and power window cables. My Haynes manual doesn't give much detail about how to actually remove the regulator....just says use a punch to knock the 4 rivets out of the panel and remove it. The sketch is virtually useless, too.
Do I remove the regulator with the entire lifter arm still attached, or does the arm need to be separated at one of the pivot points between the motor and the window? Looks like it would be tricky getting the entire arm and assembly out the hole in the door panel.
Also, I'm not sure how the top end of the lifter arm attaches to the bottom of the window. Does it just slide into the horizontal metal channel at the bottom of the window or are there other fastners?
