Why is the Mazda6 air conditioning cooling effect not good?

[VanCali]

Here is a detailed introduction to the reasons why the Mazda6 air conditioning cooling effect is not good: 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 relatively rare but not unheard of. The flap motor is usually located in the lower 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 will only come out through gaps. 3. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. If spring willow catkins accumulate on the condenser, it can cause issues such as high engine temperature or poor air conditioning performance. When cleaning, be sure to first use compressed air to blow away debris before washing with water, 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: If the low pressure is high and the high pressure is low, the compressor needs to be replaced. Faults in the expansion valve or 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 recommended for replacement 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 performance.
