Where are the automobile evaporation box and the warm air tank on the dashboard, and how do the blowers cooperate?

The radiator tank of the automobile is in front of the engine, the intercooler is in front, and the radiator tank is under the workbench near the driver and the co-driver. When the car is driving for a long distance, the thermometer pointer is in the middle position (that is, 60-80 degrees), the thermostat automatically opens, and when the heater switch is turned red, the heater fan blows out hot air. The heater water tank and the fan of the car are a whole, which is called the heater assembly. I hope it helps you.
