Description
The solar sensor, which is installed on the upper side of the instrument panel, detects sunlight and controls the air conditioning auto mode. The output voltage from the solar sensor varies in accordance with the amount of sunlight. When the sunlight increases, the output voltage increases. As the sunlight decreases, the output voltage decreases.
The air conditioning amplifier detects changes in the output voltage from the solar sensor.
