When the sunload sensor is checked indoors or in the shade, an open circuit might be indicated. It measures the amount of sunlight that is hitting the interior of the vehicle, which helps to determine the temperature setting of the climate control system. As the sun load increases, the voltage decreases. Resistance in the sensor increases as sun load increases. As the ambient temperature sensor plays a direct role in the automated function of the AC system, when it is having a problem this may interfere with the systems ability to cool the vehicle. It is the job of the ambient temperature sensor to measure the external temperature of the vehicle as a reference point for the computer to make calculations.
