Checking the windshield wipers (Mercedes-Benz Sprinter 903)

When you press the washer button, the pump in the tank starts working and water is supplied to the windshield in three streams through the nozzles located on the hood. When the steering column switch is moved to position "1", the wipers start working in intermittent mode. In position "2" the pause in operation increases, in position "3" the cleaners, on the contrary, work faster. If after using the wipers there are streaks left on the glass, it is time to replace the blades. Replacement should be done approximately once every six months.
