Wuling Hong Guang, the car heated the cold air blown by the heater. What happened?

Hello, my friend, what you said is that the hot water in the engine does not circulate in the warm air tank in the car. Of course, this will happen. This situation is usually caused by the blockage of the heater tank. You can go to the repair shop and let the master blow it with high-pressure air. You need to remove the two water pipes of the warm air tank and blow them through. It's simple. I hope my answer can help you. Please feel free to contact me if you have any questions.
