ok , my window doesn't roll down anymore. However I know the motor works (once it is dismounted from current spot).

recently I bought a new motor thinking it was a bad motor that prevented my window from rolling down. They sent me the wrong part, but to be sure I took out the old motor, as soon as I removed the last bolt I heard a POP sound as if something got unbounded.

Sure enough they sent the motor for the passenger side, rather than driver side. While the door was apart I reconnected the motor, and tested the switch, the motor ran fine. Thinking the POP sound released something I reinstalled the motor.

The window rolled up and down for several times, until all of the sudden the same scenario ...stuck in the rolled up position.

I think the gear on the window crank is moving too far and not meshing the teeth on the window crank to the window motor.

Is there some kind of STOP on the travel of the window mechanism so that motor won't travel on the window's gear too much and unmesh itself. or is the travel dictated by the motor solely, by some kind of revolution counter?

I don't quite understand how the motor stops turning, with the motor outside of the door and I press the Up or down button, it continuously turns until I lift my finger off the switch. Please explain.

Thanks

Chris

 

When motors get old they will over heat and stop working and then start again. But it does sound like you have some other problem in there. the regulators I have seen do have a stop to keep it from over cranking and messing things up. May be yours is broke. They do come out and you can test them while they are out.

to see if that regulator has a stop somewhere.

any clues how the motor stops turning? Maybe when it feels a certain amount of resistance it throws a switch?

hmmm

 

The last time I replaced a motor there was a half gear that the motor turned one way or the other and when it got to the end it stopped. very simple design. it is alot like a or any other wind motor they have a armature, brushes ect. just a tiny version.
