When does the HVAC fan turn on and off?
In normal operation, when your thermostat is set to “auto,” it will tell the blower fan plus the heating or cooling components to turn on and off at the same time when the desired temperature is reached.

Usually when the relay switch is broken, the fan will continue to run by itself. This happens because there’s no communication between the thermostat and the blower fan.

All fuses good all relays good. The fan blower for your ac/heater is located under the glovebox. Take your hand and smack the fan blower motor a few times. That’s all it took for for mine to start working again. It’s been working for over 6 month’s now!
