Sensor Assembly

The sensor assembly, located behind right side of the instrument panel above glove box, samples interior air. It contains a bi-metallic disc which reacts to the air temperature, resulting in a change in vacuum signal. The temperature control lever is attached by a cable to an arm in the sensor.

By adjusting the lever, a vacuum bias is created. Thus the modulated vacuum output is a result of both the temperature control lever bias and the air temperature sensed at the bi-metallic disc.
