Sensors
The solar sensor, located on top of the instrument panel near the windshield, monitors the solar heat.
The climate control system uses the sensor information to adjust the temperature, fan speed, recirculation, and air delivery mode for best comfort.
If the sensor is covered, the automatic climate control system may not work properly.
