What are the reasons for the BYD S6 air conditioner not cooling?
2 Answers
BYD S6 air conditioner not cooling reasons include excessive refrigerant, insufficient refrigerant, excessive impurities in refrigerant and frozen engine oil, and minor blockages. Excessive refrigerant: If the refrigerant in the air conditioning pipeline exceeds the standard, the pressure in the system pipeline will rise accordingly, which instead leads to poor heat dissipation in the system, making the air conditioner not cooling phenomenon more severe. In this case, the excess refrigerant must be removed. Insufficient refrigerant: A slight leakage of refrigerant in the system causes insufficient refrigerant, thus the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease. When the refrigerant evaporates during the evaporation period, the amount of heat absorbed will also decrease accordingly, leading to a reduction in cooling capacity. In this case, refrigerant needs to be added. Excessive impurities in refrigerant and frozen engine oil, minor blockages: In the entire air conditioning system, if there are too many impurities in the refrigerant and frozen engine oil, the filter screen of the filter will inevitably become clogged, affecting the cooling passage capacity to decrease and resistance to increase. The refrigerant in the expansion valve may also decrease proportionally, thus affecting the insufficient cooling capacity. It is necessary to go to a repair shop to find professionals to clean the blockages.
As a BYD S6 owner, when I encounter the air conditioning not cooling, my first suspicion is insufficient refrigerant. After a few years of use, there might be minor leaks in the pipelines, causing the refrigerant to slowly decrease, resulting in no cold air. Secondly, the condenser might be clogged with dust or debris, especially during spring when there's a lot of tree fluff, poor heat dissipation directly affects cooling performance. Another issue could be compressor failure, which is a core component—if it breaks, the system stops working entirely. I would simply check the air conditioning filter and replace it if it's clogged. For these common issues, it's best to promptly take the car to a repair shop for a professional fix to avoid the air conditioning failing during summer and preventing long-distance travel.
