What are the reasons for the Panamera's air conditioning not cooling?

[ChloeFitz]

The reasons for the Panamera's air conditioning not cooling are as follows: 1. Damage to the air conditioning compressor, throttle valve, or expansion valve: There is a saying in the air conditioning compressor industry, 'Low pressure high, high pressure low, replace the compressor.' The probability of air conditioning compressor damage is not high, but faults in the expansion valve and throttle valve directly lead to poor air conditioning cooling. 2. Lack of refrigerant: Because the sealing device of the air conditioning system is not absolutely sealed, the refrigerant in general air conditioning systems tends to dissipate. Therefore, ordinary vehicles need to have refrigerant replenished every 2-3 years. Some vehicles may even require it once a year. If the car's air conditioning and cooling equipment are not functioning well, after replenishing the refrigerant for a period, it may start to cool poorly. When this happens, the condenser may be leaking. The method to check for leaks is also quite laborious. Generally, a fluorescent agent is added to the oil, and a special glass is used to inspect, then the leak point can be identified.
