Abstract
A venting arrangement for an automotive vehicle is provided in which its rear closure is automatically raised to a slightly open position in response to opening a door of the vehicle so that upon closing the door, entrapped air in the vehicle can escape through the rear to reduce door closing effort. The arrangement includes a latch and pull down mechanism for the rear closure of the vehicle to move the same between a partially open and a closed position and a control means including door jamb switches for energizing the pull down unit to raise the rear closure to its partially open position in response to opening movement of the door and to return the same to its fully closed position in response to closing of the door.
