determining an imminent risk or actual occurrence of window fogging by the controller or a different controller according to one or more user inputs provided by actuating one or more of a window wiper system, a heated windshield system, and a heated backlight system;
by the controller or a different controller, increasing a climate control system blower speed to increase an airflow provided by the automatically selected climate control system operating mode based on the determined imminent risk or an actual occurrence of window fogging and directing or redirecting the increased airflow against one or more vehicle windows;
by the controller or the different controller, redetermining the imminent risk or actual occurrence of window fogging and further transitioning the climate control system operating mode sequentially through the outside mode, the air-conditioning mode, and the defrost mode; and
providing intervening steps of, by the controller or the different controller according to the redetermined imminent risk or actual occurrence of window fogging, further increasing the climate control system blower speed to increase a rate of airflow and directing or redirecting the airflow against the one or more vehicle windows.
