Housing Assembly HVAC: Description and Operation
The recirculation feature is driven by the air inlet valve. The valve is linked to a vacuum actuator that is controlled by the mode knob of the
control assembly. The valve allows fresh (outside) air to enter the passenger compartment when open. The valve will force the passenger compartment air to be recirculated when the valve is closed.
