I had a problem with my F150 and the motor had a dead spot. So on the Mustang
I slammed the door several times with switch pressed and it didn't help also
pounded on the side of door but still didn't work.

After sitting overnight like I said it has worked fine.
I know the problem will come back it's just a matter of time.

Hard to find a problem when everything works..

Is there any thing in the auto down feature that could cause this problem?
And where is this auto down controller? Next to the motor?
In the door some where??

Thanks
