What Causes the Intermittent Abnormal Noise in the Air Conditioning?

[DakotaFitz]

Reasons for intermittent abnormal noise in the air conditioning: 1. Damaged electromagnetic clutch of the compressor or abnormal noise from the air conditioning compressor. As a high-speed rotating component, a faulty compressor with severe internal wear can produce abnormal noise; 2. Excessive wear or damage to the blower motor; 3. Foreign objects in the blower, insufficient cooling oil leading to dry or near-dry friction on the contact surfaces may also cause abnormal noise. The car air conditioning refers to the air conditioning device installed in the vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.
