Wiper service mode is a special function that locks the wiper blades in an upright (vertical) position, making replacement and cleaning easier and helping prevent the blades from freezing to the glass in winter.
Windshield wiper blades are attached to the wiper arm using various mounting systems, which differ by car manufacturer, model, and year.
Winter brings snow, ice, and freezing temperatures that challenge standard windshield wipers.
