System Operation
The intake door control determines the intake door position based on the position of the recirculation switch. When the recirculation switch is depressed
the intake door motor rotates closing off the fresh air inlet and recirculating the cabin air. If the recirculation switch is depressed again, the intake door
motor rotates in the opposite direction, again allowing fresh air into the cabin.
In the AUTO mode, the front air control determines the intake door position based on the ambient temperature, the intake air temperature and the
in-vehicle temperature. When the DEFROST, or OFF switches are pushed or A/C switch is OFF, the front air control sets the intake door at the fresh
position.
