Control System Inputs

The climate control assembly has 3 system control inputs:

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, A/C, A/C RECIRC (Hybrid), FLOOR/DEFROST or DEFROST positions, the A/C compressor will be operational. The function selector switch can be installed separately from the climate control head unit.

Temperature Control Switch -   The temperature control switch setting determines the air temperature. Temperature selection is accomplished through a cable connected to the temperature blend door. Movement of the temperature control switch from COOL (blue) to WARM (red) causes a corresponding movement of the temperature blend door and determines the air discharge temperature that the air distribution system will maintain. The temperature control switch can be installed separately from the climate control head unit.

Blower Motor Switch -   The blower motor switch controls the blower motor speed by adding or bypassing resistors in the blower motor switch resistor in all function selector switch positions except OFF. The blower motor switch can be installed separately from the climate control head unit.
