It's not that much of a mystery because I figured it out what's going on, but why?

My rear passenger side window will creep down a little when I start the car. It audibly and visibly noticable. I just started and restared about three times and it moved down about 1/2 inch. I just ran out of warranty so I thought I would start here.

I checked the battery and the little status window is green, but it is 3 years old.

Any help is appreciated. I can't be the only one out there.

Thanks.

 

Short in the window switch or the motor? I would try this:

1 - Unplug the window switch for the front door (gotta remove the inner door panel) - see if that fixes it
2 - If that doesn't solve it, plug that back in and do the same thing for the rear passenger side window switch.
3 - If all else fails, try swapping the window motor from the rear driver's side

 

check power and ground connection on the window motor might be loose and that might be the prob.
