Hello,
I have a problem with the driver door window. It rolls down nice and easy but when i roll it back up, it goes good up until a certain point and it seems to get nocked off its "track" like this...

and then it stops rolling up cause it feels like its jammed, so then i have to put my hand on it and shove it back into the window like this...
its nice a crazy huge deal, but its just really annoying for the summer time
Do you know of anything i can do to fix it?
Thanks a lot guys!
