What Causes Engine Vibration When Turning on the Air Conditioning?

[AngelinaFitz]

Reasons for engine vibration when turning on the air conditioning: 1. The air conditioning compressor malfunctions, causing excessive pressure during operation, which leads to vibration issues and subsequently affects the engine, causing resonance vibration. It is necessary to have it inspected and repaired at a repair shop or 4S store; 2. The throttle valve is clogged, affecting the engine's air intake function, leading to poor ventilation and abnormal engine vibration. The throttle valve needs to be inspected and cleaned; 3. Severe engine carbon buildup is the main cause of vibration. If carbon deposits are not effectively cleaned, they will affect normal fuel combustion, resulting in abnormal engine vibration. Timely cleaning of engine carbon deposits is required.
