A system and method for automatically operating an HVAC fan for an automotive vehicle is provided where the vehicle includes an occupant detection system and an HVAC system including an HVAC computer. The user sets the heating/cooling temperature of the HVAC system to maximum and then sets the HVAC system to an automatic mode. The occupant detection system determines if there is at least one occupant inside the vehicle. The HVAC computer then automatically operates the HVAC fan based on a response from the occupant detection system.
