Why does the BMW X3 air conditioning suddenly stop cooling?

[AdrielLee]

BMW X3 air conditioning not cooling can be caused by issues with the condenser, air conditioning pump, or refrigerant levels. Condenser: If there are leaks in the condenser, it can cause refrigerant leakage, leading to the air conditioning not cooling. The condenser should be replaced at a 4S shop. Air conditioning pump: Check if the air conditioning pump plug has power, and disassemble the air conditioning pump to observe whether the bearing is stuck or if the internal piston is working properly. This can help identify the cause. If the air conditioning pump is faulty, it will result in the air conditioning not cooling. Low refrigerant: If the pressure is too low, it can confirm that the air conditioning is low on refrigerant. Without sufficient refrigerant, the air conditioning will not cool. Precautions: Regularly maintain the vehicle and inspect the condenser to ensure it is functioning properly.
