So, I had the front wipers on intermittent and the back one off. It was raining slightly at the time. I noticed that, without being switched on , the rear wiper made about 5 passes and then stopped. Has anyone else noticed this ?
Usually does this after a rear wash wipe. Then a final single wipe after a delay.
I already have the repair kit ready. But, unless it happens again, I won't do anything for the moment.
I would try to clean the whole assembly especially the inside. contact blades .
In sometime case , the dirty,whater infiltration do much problems.
Good point - if the self-parking switch in the motor is faulty, that would explain the uncommanded running (with no tailgate wiring fault). The wiper is trying to park itself but the contacts aren’t closing when the wiper reaches the park position.
Meanwhile I just had to convert 20cm into inches.
