Windows work -- then do not work -- then work again -
Suggestions?

 

Hi! Had the same problem in my 94' DeVille. It would work sometimes and other times not. Also sometimes it would have a slow crawl. I ended up ordering a new window motor and before I put the door back together tried the button and definitely was problem, works better than before!

 

Used master with $40.00 plus labor corrected the problem.

 

Do know why it's work on random basis?
is there any specific problem or limitation or need to adjust any other parts.

please advice from your end guyz
