My 1993 US spec Cruiser has air leaking in on the front passenger side window. It is very annoying and I need some help fixing it. I finally had my son drive while I sat in the passenger seat and isolated the source. The air is coming on the rear vertical part of the window, near the top. It is coming in on the tract in which the window goes up and down, not through where the window frame on the door rests against the foam rubber on the body frame. Does that work picture make sense? I wedged a folded business card up in the window tract and that reduced, but did not eliminate, the noise. Is there a forum approved fix for this?
