Windscreen wiper — general information (Renault Scenic 1)

The windshield wiper drive is located under the windshield in a waterproof fairing unit.

The speed of the windshield wiper and washer is regulated by the central switching unit depending on the vehicle speed. If the vehicle is stationary, the speed of the windshield wiper decreases. As the vehicle speed increases, the stroke of the brushes accelerates.

The glass cleaner performs only one stroke if the switch is pressed lightly. If pressed longer, the cleaner performs three strokes.

As the speed increases, the air flow pressure on the brush holder levers also increases. If the glass cleaner is currently set to the second stage, the electronics automatically switch it to the first stage so that the brushes clean the glass better.

In the event of mechanical blocking of the windshield wiper, for example, due to freezing of the brushes, the system cuts off the power supply to the drive electric motor to prevent it from burning out.

The rear window wiper is automatically turned on when reverse gear is engaged, even if the front window wiper is turned off.
