Why is the BYD Tang's air conditioning not cooling?

[KinsleyMarie]

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.

When the BYD Tang's air conditioning fails to cool, it is often caused by simple faults. The most common issue in the refrigeration system is insufficient refrigerant, which may be due to small leaks leading to low pressure. A faulty compressor can also stop the cold air output, sometimes caused by a failed electromagnetic clutch. In terms of electrical circuits, check if the fuse has blown, especially under high-temperature conditions where increased load can cause burnout; relay failure or control module abnormalities are also common. For self-inspection, first test whether the air conditioning panel settings are correct, ensuring the internal and external circulation modes are not mistakenly operated. If the air conditioning fails while driving, it is recommended to pull over immediately, open the windows for ventilation and cooling, and avoid continuing to drive at risk. Timely replacement of parts and regular refrigerant top-ups can extend the lifespan, and these small tips can save a lot on repair costs.

There are various reasons for the air conditioning not cooling in a BYD Tang. Refrigerant leakage is one of the main causes, requiring a check of whether the pipelines are intact. Compressor or fan failure can lead to cooling inefficiency. Electrical issues such as blown fuses should also be prioritized for inspection. Try restarting the system yourself or checking if the filter is clogged. Improper handling can affect driving safety, so remember to repair it promptly.
