184000463 - J02 WINDSCREEN WIPERS NOT WORKING

With the key in the ON position, when the lever located on the right of the steering wheel is operated, the windscreen wipers do not work properly.
If the vehicle is equipped with a rain sensor, the intermittent position actually corresponds to the 'AUTO' position, i.e. depending on the sensitivity determined on the ring nut, the windscreen wiper is operated automatically if rain is detected.
