Claim:
1. An automotive ventilation system comprising: a blower fan that generates an airflow; a first heat exchanger to reduce temperature of air; a second heat exchanger to increase the temperature of the air; a plurality of center face vents downstream of the second heat exchanger; a plurality of outer face vents downstream of the second heat exchanger; and at least one distribution door comprising a planar body, positioned between the first heat exchanger and the second heat exchanger for forcibly diverting at least a portion of airflow through the first and second heat exchanger; the at least one distribution door rotates on an axis, adjacent to the axis the at least one distribution door has an outboard side, opposite the outboard side at a width is a inboard side; wherein the at least one distribution door has a tab protruding from the planar body of the at least one distribution door, the tab spanning from the outboard side toward the inboard side at a length, the length of the tab is smaller than a width of the distribution door; wherein the airflow that flows across the inboard side of the at least one distribution door primarily flows to the center face vents, the airflow that flows across the outboard side of the at least one distribution door is disrupted by the tab and primarily flows to the outer face vents.
