How to Tell If Your Car Air Conditioning Compressor Is Damaged

1‌.Check the cooling effect‌:

• If the cooling effect of the air conditioning system is weakened or there is no cold air at all, it may indicate that the compressor is faulty. The compressor's main function is to draw in low-pressure refrigerant gas and compress it into high-pressure gas, thereby increasing its temperature and pressure to release cold air. If the compressor fails, the refrigerant cannot be compressed and circulated, resulting in no cooling effect.‌

‌2.Listen for abnormal noises‌:

• Another possible indication is abnormal noise in the air conditioning system. If the internal parts of the compressor are damaged or worn, they may produce harsh or unusual noises, such as hissing, knocking, or other abnormal sounds. This could be a sign of compressor damage.‌

3‌.Inspect the compressor clutch‌:

• In some vehicle models, the compressor clutch connects and disconnects the transmission between the compressor and the engine. If the clutch malfunctions, the compressor may not start or stop working properly. You can make a preliminary judgment by observing whether the compressor clutch is operating.‌

‌4.Check electrical connections‌:

• Examine whether the wiring and electrical connections of the compressor are normal, including the power supply and ground connections. Damaged wiring or poor contact may prevent the compressor from working properly.‌

5‌.Measure resistance and power-on situation‌:

​

• Additionally, measure the power-on situation. If the compressor does not start despite normal resistance readings, try replacing the starting capacitor. If it still fails to start, the compressor is likely damaged.‌

​

• Use a multimeter to measure the resistance between the compressor's terminals (S, R, C, representing the starting winding, running winding, and common terminal respectively). Normally, the sum of the resistances between SC and RC should be close to the resistance between RS, with only slight deviations allowed. Significant differences may indicate compressor damage.

​

6. Observe for overheating or unusual smells‌:

• If the compressor overheats during operation or you notice a burning smell or oily residue around it, these could also be signs of internal compressor faults.‌
