What to Do If the Air Conditioning Cooling Effect of Wuling Hongguang Is Poor?

Check whether the air conditioning system is short of refrigerant. The refrigerant needs to be checked and replenished every two to three years. If the condenser of the air conditioning system is dirty, which is common in summer due to more insects, it needs to be cleaned. Also, inspect the air conditioning belt for aging or slipping issues and replace it promptly if necessary. Here are the reasons for poor cooling effect of car air conditioning: 1. Low ambient temperature. If the ambient temperature is below 16 degrees, turn on the low-temperature compensation switch. If there is no heating when turned on, follow the mechanical air conditioning non-start detection method to check the heating wire and magnetic temperature switch. If the heating wire and magnetic temperature switch are normal but there is no voltage input, it can be determined that there is a fault in the main control board or wiring. 2. The compressor lacks refrigerant. Add refrigerant. 3. The compressor lacks oil. 4. Check if the capillary tube is blocked by dirt, oil, or ice. If the air conditioning sometimes cools and sometimes doesn’t, it is usually an ice blockage. If nitrogen is used to blow the pipeline and dirt or obstruction is found, it indicates a dirt or oil blockage.
I've seen many cases of poor air conditioning cooling in Wuling Hongguang. The refrigerant might be insufficient; it tends to leak over time, especially in older models. You should check the pipe joints for oil stains, which indicate a leak. A non-working compressor is quite common—turn on the AC and listen for a humming sound or no sound at all. Clogged filters are the most frequent issue; check the manual for the location and clean out the dust for immediate improvement. If the fan is stuck, heat dissipation is poor, and the air from the vents feels hot in summer. A condenser covered in dust also needs cleaning, as it affects cooling efficiency. If you're not handy, it's best to visit a repair shop to have them test the high and low pressure and circuits with tools—it costs money but solves the problem for good. Develop a habit of regular checks, like cleaning the filter every season, to avoid many issues. If all else fails, roll down the windows for ventilation to avoid overheating on the road.
