What Causes Loud Buzzing Noise and Vibration in Car Air Conditioning?
1 Answers
Car air conditioning producing loud buzzing noise and vibration may be caused by the following reasons: 1. Dirty air filter leading to excessive noise. 2. Debris in the blower fan blades: You can check this by turning on the blower without starting the engine. If the noise appears, it confirms the blower is the issue. 3. Deformed fan blades or damaged fan motor in the car air conditioning system. 4. Worn clutch bearing inside the air conditioning pump causing increased engine noise when the AC is on: This component cannot be replaced separately and requires replacement of the entire air conditioning pump assembly.
