What Causes the Sizzling Sound When Turning on the Car Air Conditioner?
1 Answers
Car air conditioner opening with a sizzling sound may be due to loose belts and increased load when the AC is turned on. The vehicle air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the car, providing a comfortable environment for passengers. Here is an extended introduction: 1. Compressor belt noise: The sound may be caused by a damaged compressor belt tensioner or a faulty compressor, typically heard in the engine compartment. 2. Blower fan noise: This is not only heard when the AC is on but also when the external circulation is activated, usually coming from inside the glove box, often producing a ticking sound.
