Control Assembly: Description and Operation
FUNCTION SELECTOR SWITCH
The function selector switch combines a vacuum selector valve that determines air distribution and an electrical switch to supply battery voltage to the
A/C compressor circuit and the blower motor circuit. When the function selector switch is in the MAX A/C, DEFROST or FLOOR/DEFROST positions,
the A/C compressor will be operational regardless of the A/C request switch status.
