Control Assembly: Description and Operation
Control Assembly
The control assembly in the instrument panel contains three controls: a switch to control blower speed, one rotary knob to select the desired operating
mode and a second rotary knob to control air temperature.
The controls are lit when the headlamps are on. Voltage is provided by the instrument panel lighting circuit. The control assembly lamp is in parallel
with the instrument cluster bulbs, the radio dial bulb, and certain other interior illumination bulbs. Brightness of the dial illumination is controlled by the
dimmer control of the headlamp switch.
