It looks like one of my vent windows is out of adjustment/alignment. It's only been since 1983, when I bought the car but, today I looked at it and decided I needed to fix it. The noise of the draft, seems to be bothering me today. The window is closed all the way, but the top part of the "triangle" doesn't close all the way, making a gap in the seal from window sash to gasket. Is there an adjustment that can be made?? There is a screw right below the vent window?? Does that have anything to do with it??
Thanks

Have you check the condition of the seal?There is ajustments on tilting the window.the door panel has to come off and there is a nut and screw adjustment about have way dowm the door screw it out and the window tilts inward screw it in and the opposite.

The Fisher body manual, if I remember correctly, has some adjustment instructions and diagrams of the adjustment locations. If you haven't done it before, it'll take some time to get it right.
