Abstract
A system for controlling a fan in a vehicle having a heat exchanger may include defining first and second geographic areas and determining a geographic location of the vehicle. A processor may be programmed to send a signal to operate the fan in a first rotational direction to move air through the heat exchanger in a first direction, and to send a signal to the fan to operate it in a second rotational direction opposite the first rotational direction to move air through the heat exchanger in a second direction opposite the first direction when a plurality of conditions are met.
