So its hammering it down I decide to put the pas window up and crunch bang the window starts doing the river dance! Up down uo down and for the finally drops all the way down now when I press the bottons it just makes a crunching noise and no movement, I haven't taken the door card off yet but will be tomoz, could anybody tell me what's what with this and any heads up on what I will need tools and parts wise?? Thank you
