Housing Assembly HVAC: Description and Operation
HVAC Module Airflow Modes
Air Conditioning / Recirc
The air conditioning compressor may be energized in any mode by depressing the A/C switch. This will cause the air passing through the evaporator core
to be cooled and dehumidified.
When the Recirc button is depressed the recirc motor moves the air inlet valve from outside air to recirculate air position. In this position air from the
passenger compartment is recirculated through the module. This function allows for maximum air conditioning performance. The use of Recirc in cold
and damp or humid weather will cause the windows to fog up.
BI - Level
When selecting the Bi-Level mode, air enters the module and passes through the evaporator core. Depending on temperature lever position some air may
pass through the heater core. This air will then mix with the cooler air and then be discharged through the instrument panel and heater outlets.
