Control Assembly: Description and Operation
HVAC CONTROL - GENERAL DESCRIPTION
The operation of the A/C and heating system is controlled by the buttons, rotary switch, and knobs on the HVAC control head. The compressor clutch,
rear defog and recirc motor are controlled electrically by push buttons on the control head.
Blower speeds are controlled in all modes by a five position rotary switch. The blower, compressor, and recirc motor are not operational when the
blower switch is in the Off position.
The temperature knob controls the temperature door through a cable from the HVAC control assembly to the HVAC module. The mode knob controls
the various mode positions using an actuator located on the HVAC module.
The control head logic will automatically select outside air and A/C whenever defrost and heater/defrost is selected, regardless of the A/C and
recirculation button position.
