Air Inlet Actuator
The
air inlet actuator closes the outside
air inlet so that air from the inside of the vehicle is recirculated through the A/C system for maximum cooling. The outside air inlet is closed when vacuum is applied to the actuator. When the air inlet actuator valve is vented, the spring returns the recirculation valve to the open position, which allows outside air to be drawn into the vehicle. The
air inlet valve is controlled by the inside air and outside air selector on the
heater-A/C control assembly.
