What are the reasons for the loud noise in Volkswagen's air conditioning?
1 Answers
Volkswagen's air conditioning noise is loud due to compressor damage, requiring compressor replacement; it could also be an issue with the tension of the compressor belt. Solutions for loud car air conditioning noise: If the noise is caused by damaged fan bearings, generally replacing the damaged parts will suffice. If the exhaust fan blades are deformed or the exhaust fan motor is damaged, leading to loud noise, the exhaust fan needs to be replaced. If the noise is due to excessive dirt inside the air conditioning system, cleaning the air conditioning is necessary. If the fan is damaged, the fan needs to be repaired. Solutions for damaged air conditioning compressor: Tapping method: After turning on the air conditioning, tap the lower half of the compressor with a wooden hammer to vibrate the stuck internal components and get them running. For compressor shaft seizure or cylinder jamming faults: The specific repair method is the tapping method, as described above. If there are issues with the air conditioning compressor motor part, such as thermal protector failure or the compressor's suction and exhaust valves not closing tightly, replacement is the solution. High-voltage start method: Use a voltage regulator to increase the power supply voltage before starting. Capacitor start method: Connect a capacitor with a larger capacitance than the original one to the circuit for starting.
