1, maybe the hot water pipe is broken. Check the engine warm water pipe. If there is no warm air in the car, we can first touch whether the two warm water pipes of the engine are hot. If it is hot, it means that the water temperature is still fine.
There is something wrong with the thermostat. Check whether the thermostat is good or bad. If we feel that the hot water pipe is not hot, there may be something wrong with the thermostat. It may have started too early, so the water has completely dispersed before it rises, so there is no hot air or hot air is not good, and a new thermostat needs to be replaced.
3. See if the air-conditioning filter element is dirty. If it is blocked, there will be no wind. Turn on the blower, adjust the wind speed to the highest, and see if the blower works. If the blower works, change the direction of the air outlet to see if there is wind. If it is out of the wind, it is likely that the wind direction was copied off, resulting in no wind.

Matters needing attention in turning on air conditioning in the car in winter
1. Under the mode of turning on the internal circulation of the warm air conditioner for a long time, the air inside the car is not fresh, especially the space inside the car is not large, so when turning on the air conditioner in winter, you should pay attention to opening the window regularly for ventilation.
2. When the warm air is turned on in the car, it is best to open the window halfway to allow air to circulate, and turn on the convection mode, which can prevent the car from drying and improve the air quality inside the car.
3. Pay attention to turn off the air conditioner after using it and before parking. The warmth in the air conditioner can be maintained for a short time without worrying about being too cold. At the same time, open the external circulation system, which can clean the air duct of the air conditioning system and avoid breeding bacteria.
