Test car air conditioning compressor

1. Start by visually inspecting the compressor for any signs of damage or leakage.

2. Measure the voltage at the compressor's electrical connector using a multimeter to ensure it is receiving power.

3. Check the clutch engagement by turning on the air conditioning and observing if the compressor clutch engages and spins freely.

4. Use a manifold gauge set to check the high and low side pressures. Compare the readings to the manufacturer's specifications to determine if the compressor is functioning properly.

5. If all other tests indicate a fault with the compressor, it may need to be removed and taken to a qualified professional for further testing and repair.

Theory/Principles of Air Conditioning (Expansion Valve System)

1)High pressure side

Low pressure R134a vapor entering the compressor is compressed to become high pressure/temperature R134a vapor. This is then circulated along with lubricant oil to the condenser. As the high pressure/temperature vapor travels through the condenser, heat is released to the cooler ambient air passing over the condenser tubes condensing the vapor into a liquid. This high pressure/temperature liquid then travels through the filter drier onto the expansion valve where a small variable orifice provides a restriction against which compressor pushes.

2) pressure side

Suction from the compressor pulls the high pressure/temperature liquid R134a through small variable orifice of the TX valve and into the low-pressure side of the A/C system.

The R134a is now under low pressure/temperature vapor where heat from the cabin being blown over the evaporator coil surface is absorbed into the colder low pressure refrigerant The R134a is then pulled through the evaporator and into the


The A/C cycle begins again as the R134a vapor is compressed and discharged under pressure.

3)Heat transfer

R134a in the LOW-PRESSURE side is COLD and can absorb large quantities of heat from the air moving over the evaporator.

R134a in HIGH-PRESSURE side is HOT and the cooler ambient air moving over the condenser can absorb the heat from it.


- When the R134a pressure is low, the R134a temperature is low.

- When the R134a pressure is high, the R134a temperature is high.
