How is an A/C compressor check performed? The A/C compressor is checked for:
1 refrigerant content
2 response to control signals
3 temperature to make sure the mechanism is not overheating
4 presence of abnormal noises
The A/C compressor is driven by the engine belt. However, until the electromagnetic clutch is engaged, the pulley’s rotation is not transmitted to the compressor.
At first the noise may be barely noticeable. Over time it becomes louder, indicating that the A/C compressor needs repair.
This means the electromagnetic clutch does not engage and the mechanism does not couple with the pulley.
This occurs because the mechanism has reached the end of its service life or because of excess/insufficient refrigerant.

This mechanism is very sensitive to external factors. Most often the cause of climate-system failure is a lack of refrigerant. Proper and timely diagnostics reveal all shortcomings and let you fix them with a light repair or simply by recharging the system with refrigerant.
Other common causes of compressor failure include contamination, too little or too much oil, incorrect oil, scale, fine shavings, and loss of sealing.
Such issues can clog the entire air-conditioning system. In that case, the only option is to remove the compressor, dismantle it, and perform a full wash and cleaning.
