Temperature door for HVAC to facilitate blending

An air handling system of a heating, ventilating, and air conditioning system for a vehicle comprising:

• a housing including a first housing wall, a second housing wall, a third housing wall, an inlet section in communication with a source of air, a delivery section in communication with a passenger compartment of the vehicle, a first flow path formed in the housing, and a second flow path formed in the housing;
• and
• a temperature door pivotally mounted in the housing, the temperature door including a first sealing surface, a second sealing surface spaced apart from the first sealing surface, a third surface extending between the first sealing surface and the second sealing surface, and a plurality of cells formed on the third surface, the temperature door cooperating with the housing to form a third flow path, the plurality of cells cooperating with the third surface to control a flow of air through the third flow path;
• wherein the first sealing surface sealingly engages the first housing wall and the second sealing surface sealingly engages the second housing wall when the temperature door is in a first position, wherein the first sealing surface sealingly engages the second housing wall and the second sealing surface sealingly engages the third housing wall when the temperature door is in a second position, wherein the first sealing surface is positioned intermediate the first housing wall and the second housing wall when the temperature door is in a third position, and wherein the second sealing surface is positioned intermediate the second housing wall and the third housing wall when the temperature door is in the third position.
