So for the past few months whenever I would use the auto up feature of my driver side window it would either go up and stay up or go up then roll back down half way. I lived with it and just held the button up and closed it not using the auto feature.

WELL now it stopped working all together. Any idea's of what the problem could be?

 

Take a look at my DIYs,

The window motor can go dead, but also the rails sometimes just need to be lubricated. At least by getting the door panel off, you will be able to see and hear things a bit better.

 

I have the same problem, it was working fine before, but don't know what happened now
