In preferred form, an automobile heating and air conditioning system having a plenum chamber containing a heater core and an evaporator core, and a closable purge outlet opening into the passenger compartment. When the heating and air conditioning system is inoperative, the purge outlet allows air to flow through the plenum chamber and into the passenger compartment to prevent the formation of odor and humidity in the chamber. When the system is operative to heat, cool or ventilate the automobile interior, the purge outlet is blocked by a pivotal door which also directs air through a heater outlet for distribution into the passenger compartment.
