Window Fogging Vehicle windows tend to fog on the inside in mild rainy or humid weather. To clear the windows, use the A/C, panel, and blower controls. Direct the panel outlets toward the side windows. Recirculate without A/C should not be used for long periods as fogging may occur. Interior fogging on the windshield can be quickly removed by using the defrost mode. REAR WINDOW FEATURES Rear Window Wiper/Washer A switch on the right side of the steering column controls operation of the rear wiper/washer function. Rotating the center of the switch up to the DEL (Delay) position or the ON position will activate the wiper. Push the lever forward to initiate the wash function in any of the three positions. The wash pump will continue to operate as long as the button is pressed. Upon release, the wipers will cycle three times before returning to the set position. If the rear wiper is operating when the ignition is turned OFF, the wiper will automatically return to the "Park" position.
