Why is the BYD Tang's air conditioning not cooling?
2 Answers
BYD Tang's air conditioning not cooling reasons are as follows: 1. Refrigerant: Too much refrigerant leads to decreased cooling effect. Excessive refrigerant addition usually occurs during maintenance when too much refrigerant is added. There is a specific requirement for the proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it can affect heat dissipation, as more heat dissipation means greater cooling capacity; conversely, less heat dissipation results in lower cooling capacity. Similarly, adding too much cooling oil during maintenance can also reduce the heat dissipation of the refrigeration system. 2. Insufficient refrigerant: Insufficient refrigerant causes a lack of cooling capacity. The main reason for insufficient refrigerant is usually minor leaks in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will also decrease, leading to less heat absorption during evaporation in the evaporator. Consequently, the cooling capacity will also decrease.
I've been driving the BYD Tang for a while, and suddenly the air conditioning stopped cooling, which really gave me a headache. Last time during a long summer drive, the car was as hot as a steamer. After inspection, it turned out to be a refrigerant leak, probably caused by a small gap in the condenser. If the temperature setting is normal but the airflow isn't cold enough, it's likely an issue with the compressor or the AC belt being loose. If you want to DIY, first check if the air conditioning fuse in the fuse box is blown—it's a common cause, and replacing it might help. Another issue is the fan not spinning; leaves blocking the AC air intake can lead to poor heat dissipation. In such cases, safety first—don't force the AC to run, and get it checked at a repair shop immediately. Otherwise, the risk of heatstroke during long drives is high. Regular maintenance can prevent these issues, such as cleaning the AC filter, which makes the system more durable.
