An automobile's radiator fan will switch on and off during normal operation of the vehicle, and sometimes after the vehicle is shut off. The fan is controlled by a thermostat that regulates the temperature of the coolant in the radiator. When the coolant rises above a certain temperature, the thermostat switches the fan on to cool the radiator until the temperature drops below its limit and shuts off. The fan turning off and on is a normal part of the car's operation and is nothing to be concerned about.
The furnace fan may keep running even when the thermostat is turned off due to a malfunction in the fan relay or a problem with the thermostat wiring. This can cause the fan to continue running independently of the thermostat setting.
