What are the reasons for the Mazda 3 air conditioner not cooling?

[KennedyFitz]

Here are the specific reasons why the Mazda 3 air conditioner is not cooling: 1. Lack of refrigerant: The air conditioner lacks refrigerant. As long as the vehicle has not been involved in a serious rear-end collision or had its air conditioning pipelines and other components disassembled, which would affect the sealing, the refrigerant will not be consumed. 2. Dirty condenser: The radiator and condenser are important heat dissipation devices in the vehicle. If they are too dirty, it will lead to poor heat dissipation, which not only causes the engine to overheat but also directly affects the cooling performance of the air conditioner. Therefore, when the air conditioning performance is unsatisfactory during hot weather, consider whether the vehicle's cooling system needs cleaning. 3. Aging or loose compressor belt: Generally, the 4S shop will remind you to replace the compressor belt during maintenance. If not replaced on time, slipping may occur during use, leading to belt breakage, abnormal noise, and loss of power assistance.
