Windscreen wiper minimum standard?

Hi, with my V2 I had to find out in the rain that the windscreen wiper obviously does not stop interwall switching. Also, the wiper does not go back automatically to its initial position. The wipe-wash operation only makes a wash at the front but does not wipe. At the back it works. At the V1 everything was fine in this regard. There was also a controller in the instrument cluster. Does this mean that there is something in the wrong place? Or is this a minimal standard version of Volvo for the Dutch Protestant-ascetic market – my V2 is a Dutchman? Or could I upgrade the windshield wiper circuit with some craft (from my V1 to V2) according to the Roman Catholic motto: Who has to be given [also good view]? Jürgen
