Varying amounts of exposure to sunlight will modify its electrical return signal to the programmer to adjust system output toward cooler air; less sunlight will cause the programmer to adjust system output toward warmer air. Some multizone climate control systems have more than one sun load sensor.
Solar Sensor, Sun load sensor or Ambient light sensor.
The solar, sun load sensor, or ambient light sensor detects the heat load of the sun, elevation and azimuth. It is used to adjust the amount and direction of the cooled air through the dash vents and to control headlights operation of the vehicle.

To check the auto a/c compressor compression ratio, note on paper the low and high side gauge readings and add atmospheric pressure to both readings. Divide the high side reading (with the atmospheric pressure added) by the low side reading (with the atmospheric pressure added).The result should be between 6.5:1 and 7.5:1. A compression ratio of 8:1 or higher may cause compressor failure. Learn More…
The A/C compressor is considered the heart of the refrigeration system. Compression ratio is the technical expression for pressure difference. Compression ratios are used to compare pumping conditions for a compressor and is an efficient way to evaluate the health of an air conditioning compressor.

How long should an air conditioner compressor last in a car?
The air conditioner compressor should last the entire life of the vehicle. The car ac compressor damage is usually a sign that something else in the cooling system or car ac system is not operating properly and is negatively impacting the auto ac compressor operation.
Analysis of Denso A/C Compressor warranty claims show that in a quarter of all cases
the use of incorrect oils, such as universal oils or oil mixtures, inevitably leads to seizure and damage. This is because universal oils, are PAO-oils or mineral oils with a different viscosity to that of synthetic PAG-oils. PAO-oils do not mix well with PAG-oils and with refrigerant R134a or R1234yf, leading to poor lubrication and increased wear.
Air conditioning oil properly recharged and balanced.
Installing the Compressor without balancing the oil in the system , gives a high risk of liquid lock, due to too much oil in the A/C system!
