Manual Climate Control

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.

CLIMATE CONTROL ASSEMBLY

The climate control assembly integrates the temperature control switch, A/C request button and rear defog switch into a single unit.

The temperature control switch setting determines air temperature. Temperature selection is accomplished with a potentiometer (temperature control switch) connected to the temperature blend door actuator. 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 is an integral part of the manual climate control assembly and cannot be separately replaced.

The A/C request switch determines A/C compressor operation, except when the function selector switch is in the OFF, MAX, DEFROST, or FLOOR/DEFROST positions. The A/C request switch is an integral part of the manual climate control assembly and cannot be separately replaced.

The rear defog button signals activation of the heated backlight and heated mirrors. The rear defog button is an integral part of the manual climate control assembly and cannot be separately replaced.
