What Causes the Loud Noise from the Car Air Conditioning Compressor?

[LaAvery]

Possible reasons include loose screws, aging or loose rubber seals, issues with the tailgate lock, etc. The compressor is driven by the engine, and when the linkage between the engine and the compressor is not smooth, the compressor is prone to producing abnormal noises. Another common scenario for abnormal noises is during idle speed. The compressor is a load on the engine, and when the engine is idling, dragging the compressor can cause instability, leading to increased noise. Here is some additional information: Variable displacement air conditioning compressor: A variable displacement compressor can automatically adjust its power output based on the set temperature. The air conditioning control system does not collect temperature signals from the evaporator outlet but instead controls the compressor's compression ratio based on pressure changes in the air conditioning pipeline to automatically adjust the outlet temperature.
