An automobile heating, ventilation, and air conditioning (HVAC) unit comprises a heating, ventilation, and air conditioning case permitting the flow of interior air, an evaporator core disposed in the case for taking heat from the interior air to produce cool air, a heater core disposed in the case downstream of the evaporator core for adding heat to the cool air to produce warm air, an air mix chamber defined in the case for blending the cool air with the warm air, an air mix door disposed between the evaporator core and the heater core for controlling the percentage of the cool air and the warm air being fed into the air mix chamber, depending on the position of the air mix door, and a foot-vent communication passage defined in the case by partitioning the rear end of the air mix chamber by a partition wall extending substantially vertically along the inner wall of the case, so that the foot-vent communication passage communicates with the downstream end of the air mix chamber. The case has foot vent outlets at the lower end of the foot-vent communication passage.
