The knobs on the control head (7) control the operation of the A/C system. The compressor clutch and the blower connect electrically to the control head by a wiring harness.

The rotary temperature knob (1) controls the temperature valve through a potentiometer in the control and electric motor attached to the heater module. A rotary knob (9), which sends the appropriate electrical signal to the five solenoid valves that control the flow of the vacuum on the various vacuum valve positioning actuators, controls the modes of operation. A rotary knob, located on the control head (7), control the following blower speeds in all modes:
^ Off (2)
^ Low (3)
^ Medium 1 (4)
^ Medium 2 (5)

The temperature valve position is independent of mode selection.
