There is nothing wrong with the yellow light on the warm air panel of Zhipao.

There may be several reasons why warm air is not hot. First, the thermostat is often opened or opened too early, which makes the cooling system have a big cycle prematurely, and the outside temperature is very low, especially when the car is driving, the cold air quickly cools the antifreeze, and the warm air will not be hot if the engine water temperature does not come up. Second, the water pump impeller is damaged or lost, so that the flow through the warm air small water tank is not enough, and the heat can not come up. Third, the engine cooling system has air resistance, which leads to poor circulation of the cooling system, resulting in high water temperature and poor warm air. If there is gas in the cooling system all the time, it is likely that the cylinder pad is damaged and the gas leaks into the cooling system; If the inlet pipe of the small heating tank is very hot and the outlet pipe is very cold, this situation should be that the small heating tank is blocked and should be replaced.
