Solar Sensor

DESCRIPTION
The sun load sensor is only found on vehicles equipped with Automatic Temperature Control (ATC). This is not a thermistor type sensor, but rather a photo diode.

OPERATION
The sun load sensor responds to light intensity rather than temperature. It is used to aid in proper mode door position, temperature door position and blower speed.

NOTE: The sun load sensor is not serviceable and must be replaced if found to be defective.
