What are the reasons for the small air volume of Wuling Hongguang's air conditioner?

Reasons for the small air volume of the Wuling Hongguang S heater: The air filter is too dirty, resulting in only partial air being delivered; the air blower is overloaded, which may burn out the air conditioner motor; the regulating electrical device of the air blower malfunctions, causing the air volume to decrease. If the air filter is too dirty, replace the air filter. When turning on the car air conditioner, first check if there is hot air, listen for any abnormal noise from the blower operation, and inspect whether the air ducts are clear. The functions of the car air conditioning system are as follows: 1. Provide comfort: Improve the comfort of the in-car environment, maintaining the air temperature, humidity, flow rate, cleanliness, noise, and residual pressure within comfortable standard ranges. 2. Purify air: Cool, heat, ventilate, and purify the air inside the compartment. 3. Remove moisture: Expel moisture from the air. Dry air absorbs human sweat, creating a more comfortable environment. 4. Ventilation: Inhale fresh air, providing ventilation. 5. Filter air: Filter the air to remove dust and pollen.
I also encountered the issue of reduced air volume in my Wuling Hongguang's air conditioning. The most common cause is a dirty air filter clogging the air ducts. When dust and debris accumulate, airflow gets blocked. Another reason could be excessive dust buildup on the blower fan blades, which affects the fan's rotation. Last month, I took it apart myself and spent about an hour cleaning it, which significantly improved the performance. Additionally, prolonged parking under the sun in summer may cause the fan motor to overheat, leading to slower speeds. In such cases, letting the car cool down before use or checking if the fuse has blown is advisable. Wuling's fuse box is conveniently located under the steering wheel for easy access. If the issue persists, the reduced airflow can make the cabin uncomfortably stuffy, especially in traffic jams. Therefore, regularly replacing the air filter is a good practice. It's also inexpensive to do it yourself—just buy a new filter for a little over ten yuan and replace it.
When dealing with low airflow issues, I tend to first check if the blower fan is stuck or worn out. Excessive dust on the blades can prevent the fan from spinning, so directly removing and cleaning the blades should improve performance. Next, inspect the contact points of the control switch. Sometimes, aging switches with poor contact can cause unstable current, leading to the fan running at low speed. Try manually adjusting the fan speed settings—if there's no change, the switch likely needs replacement. Additionally, loose or leaking electrical connections can also reduce airflow, especially in older models like the Wuling Hongguang, where the wiring design is simpler and more prone to issues. These checks aren't complicated; you can use a multimeter to measure the voltage, which should normally be between 12-14 volts. However, if you're unsure, it's safer to take it to a professional repair shop. Don't overlook these issues, as they can increase the overall burden on the air conditioning system.
