14 generation crown co-pilot air conditioner is not cold, how to deal with it?

The problem of switch in the air duct, the air duct is blocked, and the air conditioning pipe is not clean.

1, the switch problem of the air duct, the main driver is natural and the co-pilot is normal, which proves that the cold air is blocked. You can try switching the inner and outer loops back and forth several times. Turn on the air conditioner and keep the external circulation. Turning on the air conditioner to circulate outside will undoubtedly lead the hot air outside the car into the car, and the refrigeration effect of the air conditioner is naturally worse. Therefore, when the weather is hot, it is necessary to switch back to the internal circulation as soon as possible after external circulation ventilation.

Of course, it can't go on forever. If the air in the car cannot circulate for a long time, it is not only easy to get air conditioning disease, but also easy to cause carbon monoxide poisoning. The best way is internal and external circulation exchange.

2. If the air duct is blocked and the air conditioning pipe is dirty, you can turn the wind to the maximum. Try the wind at the air outlet by hand. If it is found that the wind is obviously not as good as before, it is likely that the air duct is blocked. The air conditioning system of a car has an air filter, which is usually located behind the glove box of the co-pilot (there are exceptions, such as the accelerator and brake pedal).

If the filter of the air conditioner is too dirty, it must be replaced as soon as possible. The filter element that is generally used for one year needs to be replaced. If the filter element is not too dirty or the air volume is still small after replacement, special maintenance personnel are needed to help clean the air conditioning pipes and air ducts.
