SYSTEM DESCRIPTION
Component Parts
Intake door control system components are:
● Front air control
● Intake door motor (driver and passenger)
System Operation
The intake door control determines the intake door (driver and passenger) positions based on the position of
the recirculation switch. When the recirculation switch is depressed the intake door motors rotate closing off
the fresh air inlet and recirculating the cabin air. If the recirculation switch is depressed again, the intake door
motors rotate in the opposite direction, again allowing fresh air into the cabin.
