What are the reasons for the Peugeot 307's air conditioning not cooling?

Reasons for the Peugeot 307's air conditioning not cooling: 1. Condenser: The condenser is a component that is often overlooked. After prolonged driving, a lot of dust accumulates on the condenser. If the car is frequently driven on dusty roads, even more dust will gather on the condenser. Excessive dust on the condenser significantly reduces its cooling efficiency, leading to poor air conditioning performance. 2. Damage to the air conditioning compressor, throttle valve, or expansion valve: The probability of the air conditioning compressor failing is relatively low, but faults in the expansion valve or throttle valve can directly cause poor cooling. 3. Lack of refrigerant: The sealing of the air conditioning system is not absolute, so the refrigerant tends to dissipate over time. Therefore, most vehicles require refrigerant replenishment every 2-3 years. If the car's air conditioning and cooling equipment are not functioning well, the cooling performance may start to deteriorate shortly after refilling the refrigerant. In such cases, the condenser might be leaking.
