What if LaVida changed antifreeze and didn't blow warm air?

There should be water in the warm air tank. Turn on the heater switch, and then start it to circulate the water. After the warm air comes out, turn off the fire and see if there is enough water in the tank. If it is not enough, the water tank cover needs to be screwed after the cold car is started.
