Power Door Locks
Hi All;
Found this site while looking for info for the power door locks on my 1992 XLT EAWD Aerostar. I did a search of previos threads and found nothing useful.
Oviusly my door locks quit I checked my shop repair CD for this model and year and have been stimied. I have traced power to the door switches but it goes no further it goes in and comes out when button is activated and there are no visible signs of broken, frayed, or burnt wiring that I can find and no smell of hot wires. Was told to look inside the driver's side panel by the rear seat got acess found another set of fuses for the tail lights and 2 mouduals changed them from my parts van to no avail????????????
Any help will be greatly apreciated!!!

There two common modes of failure:
One is broken wires between the door and the frame. The wires go through a bellows tube between the door and the frame, and can break after many years of the door opening and closing. You need to trace the wires leaving the switch to see where the voltages stop.
The other is the waterproof hood on the motor cracks from age, and any water that gets past the window moldings will seep right into the motors and rust out the internals. I think 1992 was the first year Ford switched to the newer plastic bodied motors from the old metal cans (check to be sure). If you can't find them at your local Ford dealer, you can search your local salvage yards. I found a few over the years.
