Air Conditioning Switch: Description and Operation
The A/C switch controls the operation of the air conditioning system. The A/C switch is mounted on the heater control unit. In all modes, the A/C switch
must be in the ON in order to engage the compressor. When the A/C switch is pressed, the switch signals the A/C compressor control module that air
conditioning system operation has been requested.
The position of the temperature control lever on the heater control unit controls the air conditioning output temperature. A cable connects the lever to the
air flow door that is located in the heater case. The position of the door controls the air flow through the heater core, as the temperature control lever is
moved between the full hot and full cold positions.
