Why Is the Air Conditioning Noise So Loud When Driving?
1 Answers
Here are the reasons why the air conditioning noise is particularly loud when driving: 1. Air conditioning pump: Abnormal wear of the air conditioning pump leads to unusual noise. 2. Air conditioning belt: The air conditioning belt is loose, or the tensioner pulley has insufficient tension. 3. Blower: Leaves or debris have entered the air conditioning blower. 4. Malfunction: The blower is faulty. Below is additional information on how to resolve loud air conditioning noises in cars: 1. Replace the air conditioning pump: If the air conditioning pump is abnormally worn and produces a 'clattering' noise, it should be replaced at a 4S shop. 2. Replace the air conditioning belt: If the air conditioning belt is loose or the tensioner pulley has insufficient tension, causing a 'squeaking' noise when the air conditioning is on, the solution is to replace the belt and tensioner pulley. 3. Repair the blower: If leaves or other debris have entered the air conditioning blower, you can diagnose this by adjusting the air conditioning airflow to see if the noise changes. If it does, the blower likely has leaves or other foreign objects inside. The repair method involves removing the air filter and cleaning the blower.
