Operation
Outside fresh air enters the vehicle through the cowl top opening at the base of the windshield, and passes through
a plenum chamber to the HVAC housing. Air flow can be adjusted by the blower motor speed switch on the A/C
heater control panel. The fresh air then travels through the evaporator and the heater core then out into the vehicle
through the side and floor vents. It is important to keep the air intake openings clear of debris such as leaf particles
which are small enough to pass through the cowl plenum screen and can accumulate within the HVAC housing. The
A/C compressor can be engaged by pressing the A/C (snowflake) button on the A/C-Heater control panel. It will
automatically engage when the mode control is set in any Mix to Defrost position. This will remove heat and humidity
from the air before it is directed through or around the heater core. The mode control on the A/C-Heater control panel
is used to direct the conditioned air to the selected system outlets.
