When the car air conditioning motor is damaged, the air conditioning will fail to start. Here is an introduction to car air conditioning: 1. Introduction: The car air conditioning device (air-conditioning-device), referred to as car air conditioning, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. It provides a comfortable riding environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. 2. Composition: It generally includes a refrigeration device, heating device, and ventilation device. This combined device makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally.
As an experienced auto mechanic, I've encountered too many cases of faulty blend door actuators. The most obvious symptom is abnormal airflow – you get hot air when cold is selected, or the air direction fails to switch. If you listen carefully behind the dashboard when turning on the AC, you'll hear a 'click-click' sound of gears slipping. Last month I repaired an Audi where the seized motor couldn't even switch between recirculation and fresh air modes, causing mildew on the passenger floor mat. These motors are hidden behind the evaporator core, requiring complete dashboard removal for replacement – just labor costs over 1,000 RMB. I recommend immediate inspection at the first sign of airflow issues, as prolonged neglect can even burn out the blower motor resistor.
