I own a 2004 Subaru Forrester 2.5X. My question is concerning the windshield wiper/washer. When the wiper lever is pulled toward the driver, should the wiper operate once AND spray water or operate once but not spray water? When the button is pushed on the wiper lever, it does spray water. When the wiper lever is pulled toward the driver, it does not spray water. My dealer service manager says it is not supposed to spray water when the lever is pulled however the icon on the lever shows water being sprayed.
