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.
Do you need assistance ?
The Sun Load or Ambient Light Sensor It is usually installed on the top of the dashboard behind the windshield or in the back of the rear-view mirror.
Do you need assistance finding the Sun load sensor in your vehicle ?
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.

A high compression ratio can be caused by:
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.

***CHECK THE FAN OPERATION BEFORE MAKING ANY REPAIR TO THE AC SYSTEM***
The radiator fan(s) should be on any time the A/C is on.
Road debris affect the heat transfer of heat exchangers in your vehicle and the overall capacity of the air conditioning.
Clean all the road debris outside the car
(on the windshield)
(on the condenser coil)
Clean all the debris inside the car
In cabin air conditioning filter
Evaporator core
Screen air inlet
-Check Drive Belt tension
An excessively loose drive belt will negatively impact the air conditioning compressor capacity.
Check refrigerant charge with gauges (You need special hvac equipment and EPA certifications)
Check refrigerant charge by sensing A/C lines temperature (Do it yourself)
-Open the hood to get access to the engine compartment (Be aware of all moving parts and hot components)
-Start the engine up.
-Set the A/C Climate control for Maximum blower speed position.
-Set the A/C Climate control for Maximum cold temperature position.
-Let the A/C system run for 5 -10 minutes.
-On the engine compartment identify the A/C lines.
-The Liquid line should be warm to cool even in a hot day
. (A liquid line cold or hot indicates a problem)
-The Suction Line should be cold
. Heavy frost or excessive moisture condensation on the Suction Line indicates a problem.
. Ambient temperature or too hot Suction Line indicates a problem.
-There should be a Temperature difference (TD) between the Liquid Line and the Suction Line (Check temperature before the Metering Device)
If the temperature of both lines is the same, it indicates a problem in the A/C system:
1-Compressor not pumping.
2-Compressor not turning on.
3-Low on refrigerant.
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.
There are multiple ways to ensure the auto ac compressor last for the entire life of your vehicle.

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.
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!
