What are the reasons for Mazda 6's air conditioning not cooling?

Introduction to the reasons for Mazda 6's air conditioning not cooling: 1. Lack of refrigerant: Refrigerant wear is mainly due to leakage. If the condenser leaks, it needs to be replaced. When the leakage is severe, oil stains can be seen on the surface of the condenser through the grille, which usually indicates a condenser leakage. 2. Damaged air conditioning flap: Damage to the air conditioning flap motor is a rare but possible fault. The flap motor is usually located in the lower middle part of the instrument panel and serves as the main switch for the air conditioning vents. Once the flap is damaged, even if the air conditioning can produce cold air, it can only escape through gaps. 3. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. In spring, willow and poplar catkins sticking to the condenser can cause engine overheating or poor air conditioning performance. When cleaning, be sure to first blow them clean with an air gun, then wash with a water gun; otherwise, it may have the opposite effect, leading not only to poor air conditioning but also increased fuel consumption. 4. Damaged air conditioning compressor, throttle valve, or expansion valve: High low pressure and low high pressure indicate the need to replace the compressor. Faults in the expansion valve and throttle valve directly result in poor air conditioning performance. These checks are relatively complex and require professional repair shops. 5. Aging or loose belt: Generally, the belt will be reminded to be replaced during maintenance at a 4S shop. If not replaced, slipping may occur during use, leading to belt breakage, belt noise, loss of power assistance, and poor air conditioning.
