Looked a little for some info before I asked to no avail. My drivers side front window gets stuck in the lowered position, it seems to tilt forward and backward causeing the window to not roll up, squeaks and all that nice noise. I'm shure the problem would be obvious once I dismantle the door, but I would like to know if there is a common problem and a common part I can buy so I don't have to dismantle the door twice. thanks !
