Abstract: An air deflector is mounted in a vehicle and fixedly secured to the window channel and outer edge of the vehicular door, with a deflector plate mounted to a support boss. The support boss adjustably mounts a plurality of "J" shaped mounting plates to the boss to clamp the door frame. A modification of the invention includes plural columns of air openings through the plate directed at decreasing angles of orientation relative to the plate to direct air interiorly of the passenger compartment in limited quantities. Further, a support boss of the deflector plate is optionally provided with a through-extending conduit and feed conduit to direct a fluid fragrance through the deflector plate.
