For no apparent reason, my driver's side window developed this problem: When I roll the window up (goes down with no problem), as soon as it reaches its normal stopping point, it automatically rolls back down halfway. I then pull the button to roll it up and again, it will roll down halfway. Only on the third try will it remain up in fully closed position. I have checked the tracks to be sure nothing had become stuck in them and they are clear/unobstructed. I am hoping my fellow Touareg friends will have a suggestion to fix this. *I did try to roll window down completely and continue to hold button for five seconds, then roll up, but then it rolls back down halfway when it reaches the top. Any advice will greatly be appreciated!
