As title really, I put the window right the way down and when I went to put it back up it got stuck halfway, so I whipped off the door card and I seen straight away the glass wasn't running into the runner and getting jammed as halfway, all I needed to do to get it back up was was push the glass into the runner whilst it was going up but every time it goes all the way down it will just keep happening... I checked all the bolts and none were loose, is there anything else I should check??
