Hello, unfortunately I have no idea and wanted to ask before the passage into the workshop if someone with the problem has experiences. So my windscreen wiper at the front only goes on one side. So driver side still works, passenger side is defect. The problem is that the rail that drives the right wiper has solved itself from the holder of the wiper. I can’t see if there is something broken. I can now, if I open the bonnet, push this track again from below to the windscreen wiper, but nothing rests there and the track replaces itself after 5 minutes drive again. Does one maybe have a tip on how I can fix this, or does a part have to be replaced, since broken? I know it is difficult to say by remote diagnosis, but I would hate that there is completely changed for xxx Euro, if it would also be easy.
