184000462 - J01 WINDSCREEN/REARSCREEN WASHERS NOT WORKING

With the igntion key in the ON position, when the lever on the right of the steering wheel is operated, the windscreen wash/wipe does not work properly.

If the vehicle is equipped with a rain sensor, the intermittent position corresponds to the AUTO position, in other words, depending on the sensitivity setting for the ring nut, the windscreen wipers are activated automatically if rain is detected.
