Got the motor from Fox Mustang Restoration. Went in the driver's door on my '90 5.0 7up Vert.

Everything was fine for about a week or so, now when I close the window the gear jumps the track when the window tops out. Annoying grinding noise if I don't get off the button quickly. Window still goes up and down, no problem - just 'slips' when it tops out.

What kind of adjustment can I make to get this back in order?

Thanks.

 

maybe one of your window stops needs adjustment

 

Yes, the window is a little loose. I will try adjusting the stops. Thanks.

 

OK, so I finally got this fixed. Ended up finding a more 'stock' replacement window motor (motor that caused the issue has '1/2 extra horsepower' for some reason). Without any other adjustments, this new motor works fine. No slipping off the gear/track at the top. I did adjust the upper/center window pad AFTER the new motor was in, just to get rid of a little slop in the window.

Got the window motor from discountbodyparts.com for less than $30 bucks, has a 1 year warranty. Driver's side - Part F462944 Best price I found.
