The warm air water valve is the warm air switch of the automobile heater. The working principle of the automobile heater is that the radiator in the heater is connected with the circulating water of the engine through the water inlet and outlet pipes, and the water valve is a switch: when the water valve is opened, the water channel is connected, the circulating water of the engine enters the radiator, and the fan blows heat into the cab; On the contrary, the water valve is closed and the warm air doesn't work.
After the hot water valve fails, the opening of the electronic control valve is no longer controlled by the computer, and it is in the state of normally open, normally closed or fixed position. At this time, there is no coolant flowing through the warm water tank or the flow rate is uncontrolled, so the warm air temperature of the air conditioner is naturally uncontrolled.

Maintenance skills of warm air valve: In the season when the weather is not cold, the warm air inlet valve can be closed to isolate the engine cooling system from the warm air valve. In cold winter, before using warm air, check whether the left and right air supply pipes and air inlet and outlet pipes are loose, falling off and broken.
Check whether the heating system vibrates abnormally, whether the pipeline leaks, whether the water level of the drain tank is normal, and whether the drain pump works normally. The water temperature of the engine should not exceed 90℃ to ensure the best performance of the heating device.
