Yusheng s35 warm air has one side and no side.

hello, do you want to ask the reason why Yusheng s35 has one side of warm air and no side? The reasons why Yusheng s35 warm air has one side and no side are as follows:

1. The air conditioning filter element is broken;

2. Lack of refrigerant;

3. The passage of the warm air water tank is blocked, resulting in insufficient hot water entry;

4. If the air duct on the non-hot side is not open or blocked, check whether the control flap cable for cold and hot air in the heater box falls off, whether the heater impeller is damaged, whether the flap falls off, etc. Warm air only uses the thermal cycle process inside the car, and it is not necessary to start the compressor of the car. Warm air is formed by the heat dissipation after the engine works. Through a small fan in the engine compartment, the heat collected in the engine cooling system is blown into the car.
