The weather is cold, and the car air conditioner does not cool.

Cold weather, car air conditioning does not cool, car air conditioning does not cool, may be the following reasons: 1, condenser problem. The condenser is a very easy-to-be-ignored component, and there will be a lot of dust on the condenser when the car is driving for a long time. If you drive on dusty roads for a long time, there will be more dust on the condenser. There is more dust in the condenser, and the heat dissipation effect will be greatly reduced. The heat dissipation effect is not good, and the air conditioner is naturally not cold. Solution: Clean the condenser. The compressor doesn't work. For example, the reasons why the air conditioner does not cool after the car is exposed to the sun are: 1, the power supply is not in good contact, check whether the power supply of the air conditioner is plugged in properly, and whether the connector of the air conditioner is in poor contact with the power supply; Maintenance method: If there is something wrong with the air conditioner power supply, just plug it in again to ensure that the air conditioner can be electrified normally; 2, lack of refrigerant, the general air conditioner has been used for a long time, the refrigeration effect of the air conditioner will become worse, and the refrigerant of the air conditioner will gradually evaporate with time. In this case, you need to check whether the air conditioner itself is leaking refrigerant; Air conditioning and refrigeration need to add enough snow seeds to solve the problem of air conditioning and refrigeration; 3. The air conditioning power is insufficient. The lack of air conditioning power may be due to the small air conditioning power, but it needs to provide large space for refrigeration; In order to solve the problem that the power of air conditioner is small, but it needs to provide cooling capacity in a large space, it is necessary to match the power of air conditioner with the size of the room providing cooling capacity to increase the tightness of the space. @20 19
