What are the symptoms of a faulty car air conditioning amplifier?
2 Answers
When the car air conditioning amplifier is faulty, it can cause the vehicle's air conditioning system to fail in cooling and functioning properly. Here is additional information: 1. Introduction: Car air conditioning refers to the air conditioning device installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. The air conditioning system has become one of the indicators to measure whether a car is fully equipped. 2. Composition: Generally, it includes a cooling device, heating device, and ventilation device. This integrated system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally.
That day, driving long-distance was unbearably hot. I found that when I pressed the AC button, only the fan was blowing air, and the compressor wouldn’t start at all. The cabin was stuffy like a steamer. A friend mentioned hearing strange noises or switches acting up, but my car didn’t have any unusual sounds—just the fan occasionally stuttering a bit. I checked the fuses, and they were fine; the relays were also normal. Later, the repair shop diagnosed a faulty amplifier, which couldn’t control the compressor clutch. Such faults might also cause unstable voltage in the electrical system, leading to a drained battery. It’s recommended to routinely inspect AC components before summer and seek professional repairs at the first sign of trouble to avoid suffering on long trips.
