What's wrong with the warm air of Baojun 51?

Why is the warm air of Baojun 51 not hot? It may be that the warm air adjusting mechanism is not working well, which leads to the cold air in the car. Or the warm air in the car caused by the engine cooling system is not hot. The method of identification is simple. Look at the temperature of the two intake pipes of the small warm air box. If the two pipes are basically hot enough, it means that there is something wrong with the air volume adjustment mechanism. On the contrary, if both pipes are basically cold, or one is hot and the other is cold, it means that there is something wrong with the cooling system. The engine cooling system may cause the automobile warm air not to be hot, which may be the problem of the cooling system. Baojun 51 air conditioning heat, turn on the warm air as follows: first turn on the air switch, turn off the a/c key, and then turn on the warm air by raising the temperature. After the car starts, after about 8-15 minutes, the water temperature rises to normal temperature, and the warm air can be turned on at this time. (that is, when the water temperature rises to the middle), adjust the circulation mode of the empty switch to the in-vehicle circulation mode and to the warm air mode. Some cars are in the red area, and some cars use the sun to say don't turn on the idle switch (don't turn on the AC switch), because the warm air uses the car's own thermal cycle to save energy! Empty adjust the gear of the blower to the appropriate gear, and adjust the wind direction of the air outlet (the direction of warm air blowing is generally positive blowing and foot blowing)
