SUN SENSOR
The sun sensor is only used on vehicles equipped with Automatic Temperature Control (ATC). The sensor is mounted on the top of the instrument
panel below the instrument panel top cover.
The sun sensor is not a thermistor type sensor but rather a photo diode. For this reason the sun sensor responds to sun light intensity rather than
temperature. It is used to aid in determining proper mode door position, temperature door position and blower speed. The sun sensor is also used
to sense day/night conditions for automatic headlight control if so equipped, and has an LED indicator for the vehicle security system.
The sun sensor is not serviceable and must be replaced if found to be defective.
