Solution: First, check whether the inlet and outlet pipes of the heating box are hot. If the heat indicates that the water supply is normal, the problem may be that there is something wrong with the heating water tank! The radiator pipe in the heater water tank is blocked!
2. Check whether there is a lack of antifreeze.
If there is no antifreeze, it will also affect the warm air. Because the warm air uses the heat of antifreeze, the hot antifreeze enters the warm air tank for heating, and the wind is blown out through the warm air tank. If there is not enough antifreeze, the number of small heating tubes will be reduced, so the heating tubes will not be so hot, so the wind blown out will not be so hot.
Solution: As long as the antifreeze is added to the normal level, the warm air will return to normal.

Matters needing attention in the use of automobile warm air:
1. Use warm air and don't smoke in the car:
When the temperature is low, generally close the window and use internal circulation. If you smoke in a closed environment, it is difficult to exhaust the smoke in time, which will not only affect the service life of the automobile interior, but also affect your health.
2. Don't face the air outlet:
Many people will aim the air outlet at themselves, which will make the skin dry and accelerate the skin aging. You can turn the air outlet down and control the temperature inside the car at about 20 degrees Celsius.
