Why is the Buick Regal's air conditioning not cooling?

[RyanLynn]

Buick Regal's air conditioning not cooling reasons are as follows: 1. Refrigerant loss: Check for refrigerant loss. The refrigerant in the air conditioning system, commonly known as Freon, has a decay cycle. Generally, better-quality refrigerant has a decay cycle of 3-5 years. Moreover, the air conditioning system is not completely sealed. Even in well-sealed systems, there is an annual loss of 5%-8%. 2. Poor radiator cooling: During vehicle use, wear and tear are unavoidable, and sometimes the cleanliness of the car air conditioning radiator is easily overlooked. However, many air conditioning failures are caused by radiator blockage, so it's advisable to clean the radiator regularly during car washes. 3. Compressor failure: The car air conditioning compressor, also known as the air conditioning pump, is like the heart of the air conditioning system. If the compressor fails, it indicates a major issue with the car's air conditioning, though this situation is not very common.
