Here is my problem... the left side of my car seems to have had a stroke or something. My left window doesn't work correctly... It will go down a little bit and I can go and roll it down a little more later, but It won't go up and down normally. Now I thought it was just my window, but now my mirror seems to be doing the same thing. It will go strong for a couple of seconds then it will slow down, and eventually not move any more. My right side works perfectly. Any help?

could be a bad ground, maybe a bad wire in the door jamb

yeah take the switch panel off and have a look.

I would check the wiring to the door and see if by some chance it has worn on the pivot point and where the door closes.

I would start there...
