Abstract
The present invention concerns a method for pre-cooling the passenger compartment of an automotive vehicle. The vehicle includes at least one electrically actuatable window and a HVAC system having at least a controller, a blower, a passenger compartment temperature sensor, and a HVAC ducting leading to the passenger compartment. The controller and the blower are connected to a vehicle battery. The method includes determining the passenger compartment temperature and comparing the temperature to a first predetermined value; cycling an blower inlet to an outside air intake position and operating the blower to provide pressurized air to the passenger compartment if the passenger compartment temperature is greater than the first predetermined value; opening the vehicle windows; comparing the passenger compartment temperature to a second predetermined value; and stopping operation of the blower when the passenger compartment temperature drops below the second predetermined value.
