Which fan is running...the aux fan...or the heater blower? These are two different fans in two diffent locations...used for two different things?

The aux fan is the one in front of the radiator which helps facilitates cooling when engine coolant temps get to a specific degree...and when the AC is initiated etc. The heater blower controls the air velocity for the cabin/interior HVAC system. Which fan is running after the car is shut down?

BTW, when the manual says to not disconnect the battery while the car is running...that refers to the engine. When you shut the car off...but your heater blower fan or aux fan is still running...the car is off & the engine is not can disconnect the battery at this point because the engine is NOT running.
