The warm wind in Jianghuai He Yue is neither too cold nor too hot.

Find out the reason why the warm air is not hot: 1, check the warm air system when the engine temperature reaches 80 degrees; 2. Check the temperature of the inlet and outlet pipes of the warm air water tank, and touch whether the temperatures of the two pipes are the same by hand. If one is hot and the other is cold, congratulations on your small water tank being blocked! 3. Check whether the air duct switch is normal and whether the air volume is sufficient; 4. If the air duct switch and air volume are normal, it can be judged that the reason why the warm air is not hot is that the warm air small water tank is blocked! Of course, the solution is to deal with small water tanks. If it is slightly blocked, it may be washed with high-pressure water and air, but if it is serious, it can only be replaced or repaired.
