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.
