I also posted this in general tech since it seems to fit better there and isn't specific to this engine or anything, but thought I might as well put it here too and see if I get any replies since I haven't over there yet.


I just got a new Motorcraft driver's door window motor and once I installed it and tested it before putting the door panel back on, it is going in the wrong direction. When I push down on the switch, the window goes up; when I push up, the window goes down. It's also very noisy, but obviously that's no big deal compared to the motor going in the wrong direction.

It's not possible to install it backwards or plug it in backwards, and when I plug in the new motor and the old motor with it uninstalled the gear on the new one does go in the opposite direction from the old one. The wiring that is visible is all the same, I'm assuming something is backwards inside that you can't see. Obviously I don't want to tear anything apart myself though when it's a new motor that I could just return.

I just wanted to make sure before reinstalling the old one and returning the new one, though, that there isn't some stupid simple little thing that I'm having a brain fart on. Any ideas?

Thanks guys.

Defective motor wiring? May be hooked up backwards from the factory. Try to take it back and get a new one.

Check your switch connectors and make sure no lose or crossing wires anywhere in the lines.
