General Description

The operation of the air conditioning system is controlled by a switch and levers on the control assembly. The compressor clutch and blower motor are connected electrically to the control assembly by a wiring harness. The blower circuit is open in the "OFF" mode.

AIR FLOW
Air flow is provided by the four blower speeds available in the remaining modes. Cooled and dehumidified air is available in the "MAX," "BI-LEV," and "DEFROST" modes.

TEMPERATURE
Temperature is controlled by the position of the temperature lever on the control assembly. A cable connects this lever to the temperature valve. It controls air flow through the heater core. As the temperature lever is moved through the its full travel, the cable at the temperature valve connection assures that the temperature valve will seat in both extreme positions. The position of the temperature valve is independent of mode selection. The temperature cable attaches to the air conditioning module.

FUNCTIONAL ASSEMBLIES
The remaining functional assemblies are controlled the vacuum valve linked to the mode lever of the control assembly. This valve controls the supply of engine vacuum to the appropriate vacuum actuator(s) for the mode selected.
