What Causes a BMW's Air Conditioning to Suddenly Stop Cooling?

[StCorbin]

BMW cars suddenly stop cooling due to a lack of refrigerant in the compressor. Here is an introduction to air conditioning: Introduction: Car air conditioning refers to the air conditioning device installed in a vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Structure: It generally includes cooling devices, heating devices, and ventilation devices. This combined system makes full use of the limited space inside the car, featuring a simple structure and easy operation, making it a popular modern car air conditioning system internationally. Layout: Different types of air conditioning systems have varying layouts. Currently, most passenger cars widely use an integrated heating and cooling air conditioning system. The layout typically involves assembling components such as the evaporator, heater core, centrifugal blower, and control mechanisms together, referred to as the air conditioning unit assembly.
