The indoor temperature of Baojun 730 is low this year. What should I do if the warm air is not hot?
1, heater box blocked. The structure of the heater box is actually a miniature version of the radiator of the engine water tank. There are many small cooling pipes in it, which are as easy to block as the radiator of the water tank. After the inside of the warm air water tank is blocked, the coolant flows slowly, the flow rate becomes smaller, and the heat is insufficient, so the air conditioner warm air is naturally not hot.
2. The cooling system is short of coolant. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant, which is connected with a warm air tank. After the blower blows the warm air trough, it produces warm air, which is how the air conditioning warm air comes. The lack of coolant in the cooling system is the most common and easily solved fault phenomenon that causes the warm air not to be hot.

Other reasons why warm air is not hot:
1, thermostat failure
The common fault of the thermostat is that it can't be opened, but the reason why the warm air is not hot due to the thermostat fault is that the thermostat can't be closed, commonly known as the thermostat is always open. After the thermostat is normally open, the coolant is circulating from the engine idling, and it can be clearly seen from the water thermometer that the pointer is obviously lower than the normal scale. In addition, low water temperature for a long time will lead to high fuel consumption and increased wear, so it is necessary to carry out maintenance and inspection immediately when the water temperature is low for a long time.
2, warm water valve failure
Warm water valves are common in luxury brands, and are actually electrically controlled valves. The warm water valve is installed between the water inlet pipe of the warm water tank and the small circulating pipeline of the engine, and the opening of the valve is controlled by the air-conditioning computer, so as to control the flow rate of coolant entering the warm water tank and achieve the purpose of controlling the warm air temperature of the air conditioner more accurately.
