The reasons why the air conditioning of the Baojun 730 is sometimes cold and sometimes not: 1. Lack of refrigerant: This is the main reason why most vehicles encounter air conditioning failures in summer. When the refrigerant in the car's air conditioning pipes is insufficient, the pressure in the air conditioning pipes decreases, and the amount of heat removed also decreases. This can give the impression that the air conditioning is not blowing cold air. Therefore, it is essential to regularly check the refrigerant pressure during routine maintenance to avoid leaks or insufficient pressure. 2. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. If the condenser is clogged with poplar catkins in spring or dust from smog, it can lead to phenomena such as excessive engine temperature or poor air conditioning. Therefore, it is necessary to check whether the radiator is clogged with many fibers after spring. When cleaning, be sure to first use an air gun to blow it clean, and then use a water gun to wash it, otherwise it will have the opposite effect, not only resulting in poor air conditioning but also increased fuel consumption. 3. Loose air conditioning compressor belt: This situation is caused by the aging of the compressor belt, which causes the compressor to slip during operation, reducing work efficiency, lowering rotational speed, and impairing the effective delivery of refrigerant. At this time, the compressor belt should be tightened. If the aging is too severe, it is recommended to go directly to a professional repair shop to replace the belt. 4. Air in the air conditioning pipes: If air is mixed into the car's air conditioning system during operation, it will affect the refrigerant's circulation, significantly reducing the cooling effect. The main cause of such problems is mostly the incomplete evacuation of air during the maintenance process.
