The intention is not that when the vent window is open, it closes because of the wind. To do this, Volkswagen has mounted a brake bracket on the lower part of the window, by tightening the bracket more tightly, the window will rotate more firmly.
Adjust the vent window so that it opens and closes smoothly, but remains in place in all positions, and do so before final installation, once assembled, you will no longer be able to reach it easily.
This brake is located on the central or rear vent window of the Bay Window Bus.
