What is the reason for the 2012 Magotan's air conditioning not cooling?

The reason for not cooling may be a problem with the refrigerant in the car's air conditioning system. Excessive impurities in the refrigerant and refrigeration oil of the car's air conditioning can also clog the filter screen of the filter, leading to reduced cooling efficiency, increased resistance, and a decrease in the flow of refrigerant to the expansion valve, resulting in the car's air conditioning not cooling. Here is some extended information: 1. Car air conditioning system: The car air conditioning system is composed of multiple metal pipes with small gaps between them, so there is a slight leakage of refrigerant in the car air conditioning system. Additionally, the dryer bottle in the car air conditioning system absorbs moisture and stores some refrigerant, so when the amount of refrigerant decreases to a certain level, the cooling capacity of the car air conditioning will decrease. 2. Dryer tank: There is a dryer tank in the refrigeration system of the car air conditioning, whose main task is to absorb moisture in the refrigerant and prevent excessive moisture in the refrigerant from causing a decrease in cooling capacity. When the desiccant in the dryer tank is saturated, moisture can no longer be filtered out. When the refrigerant passes through the expansion valve throttle hole, due to the decrease in pressure and temperature, the water in the coolant will freeze in the small hole, leading to poor refrigerant flow, increased resistance, or complete blockage.
As someone who has driven many Volkswagen cars, let me share my experience. When the 2012 Magotan's air conditioning isn't cooling, it's often due to insufficient refrigerant - what we commonly call a Freon leak. In older vehicles, prolonged use can cause pipe connections to loosen or deteriorate, leading to refrigerant leakage and rendering the system ineffective. Another frequent issue is a faulty AC compressor. The compressor acts as the heart of the air conditioning system; if it fails, the entire system shuts down. I've also seen cases where the condenser gets dirty or clogged with debris, impairing heat dissipation and reducing cooling efficiency. Electrical problems like blown fuses or relay failures are quite common too, especially during rainy or humid conditions when short circuits can disable the AC. You can start by checking the fuse box in the engine compartment. If that's not the issue, avoid forcing the AC to operate to prevent system damage. I recommend visiting a 4S shop for inspection before summer heat becomes unbearable. Regular refrigerant top-ups and condenser cleaning can prevent these problems - proper maintenance saves money and ensures safety.
