I am having a problem with the drivers side front window. When I roll it down I have to push it, to get it to go completely down. When I roll it back up, it trys to come in to the car. So I have to roll just a little then pull it up by hand a few times to get it all the way back up without leaks... Has anyone had this problem? Any ideas what it is. I have not taken it a part to look at anything. It seems as if it is off the track. The motor is fine.
