Hi all, my 5 door colour concept gti has developed a very strange problem. The windows on the drivers side work fine, but the passenger side windows are a different story. They move fine but when trying to close them, the window will fully close and then lower immediately to just past half way. The only way of closing them is by raising them a cm at a time.
And if i try to use the total clousure on the door look they also lower, but only by an inch or so.

Any suggestions would be appricated as its no fun sitting on leather seats for 5 mins on a warm sunny day just trying to get the windows to close !!!
