Because the heat source of the warm air comes from the engine coolant, and the coolant can only circulate in the warm air tank after the pump works to generate pressure, because the pump is damaged, the warm air disappears or is not warm.
In winter, if the additional pump of the heating water tank is broken, it needs to be repaired in time to prevent the pipeline of the heating system from freezing and cracking.
