Why does the Xuan Yi make a clicking noise when the air conditioning is turned on?
2 Answers
There are several reasons for abnormal noise when the air conditioning is turned on: 1. Reason one: The sound of the compressor belt, which may be caused by damage to the compressor belt tensioner, or it could be a fault in the compressor. This sound is usually heard in the engine compartment. 2. Reason two: The sound of the blower, which is not only heard when the air conditioning is turned on but also usually when the external circulation is activated. This sound is typically heard in the glove box and is usually a clicking noise. 3. Reason three: A fault caused by the temperature control switch inside the panel or the internal/external circulation motor, this sound is usually emitted from inside the center console panel.
When repairing cars, I often encounter the issue of the Sylphy making a rattling sound when the air conditioning is turned on. This noise is usually a sign of mechanical component failure. The most common cause is wear and tear on the compressor clutch—when the AC is turned on, it rattles due to impact, and over time, this can damage the compressor itself. Small stones or leaves stuck in the fan blades can also knock against the housing when rotating, producing noise, especially during the fall when leaves are more likely to accumulate. If the belt is too loose or cracked, it may slip and vibrate when the AC is turned on, creating noise. You can also try to locate the source of the sound: if it's coming from the front engine compartment, it's likely the belt or fan; if it's inside the car, it might be debris or loose parts in the air conditioning ducts. It's best not to delay—take it to a professional repair shop for inspection. Addressing the issue early can prevent further damage, such as compressor burnout, which would lead to higher repair costs. Often, replacing a small part can solve the problem.
