window motor glitch

I just bought 4 motors.. but don't want to put them in yet.. because I have the same problems as u sometimes.. I think some of the track parts wear out.. there is a plastic piece that apparently goes allot.. definitely check your wiring connections to see if they are corroding.. I am currently doing a paint job.. but my next step is to fix the motors... get new weather stripping.... and convertible top... sorry if that's not much of a help... do your windows wiggle around... or are they tight... mine can easily be moved and don't line up right... could strain the motors I'm guessing that's why I don't want to put them in until I know that everything else is repaired!!

If the wiring seems suspect, it tends to fail inside the weatherboot in the door jamb. All the articulation from years of door opening and closing weakens the wiring.
In your case, closing the door could have affected that, or it could be the motor just needed a jarring.

Good luck.
