15 why does the Camry heater fan turn?

Hello, first check whether the air conditioning switch is turned off. I hope I didn't turn it off. If I turn it on, the fan will keep turning. When the water temperature comes up, it turns, and when the temperature comes down, the fan stops. I hope I can help you! If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
