Sounds like the levers and whirligigs are binding and have jammed. If you can get the motor free, see if it spins when you close the switch. If you have juice at the switch and at the motor, it sounds like a mechanical hang-up (unless the motor is burned out).
I say all that without having the vaguest idea how the window winding mechanism inside the door works. I assume it's more or less like any other winding mechanism, so in my experience there is binding going on in the mechanics.
I hope that helps.
