When inspecting the air conditioner, mainly check the condenser of the air conditioner, and clean the surface of the condenser. If there is too much dust, it must be cleaned in time and compressed air blowing. During the inspection, it is necessary to check the performance of various switches and control components, to detect the reliability of their performance and whether the air conditioner is lacking in fluorine. If the vehicle's refrigerant is insufficient, this will cause the air conditioner to lose its cooling effect.
In addition, attention must be paid to whether the refrigerant leaks. It is also possible to effectively deal with the parts on the surface of the compressor by observation, mainly dealing with the oil stains on the surface of the compressor, hoses and joints in a timely manner.
