I have just bought PS5, and I have been driving some trains. Yesterday I drove the BR101 with IC cars, on the Rosenheim-Salzburg route, with Dynamic weather set. Near Salzburg, it started to snow. Then the view ahead of the locomotive through the front windows started to get complicated. So I used the wipers. But then after some few time, they stopped to work! Of course I mean with the wiper switch still in ON position! So it is really strange. This is the way it should be? Have you experienced this? Please have some pictures below. As you can see the wipers are on "vertical" position - so they are "ON"- , but - despite it is a picture, believe on me - they did not work anymore!
I remember this being a bug with TSW3 - where wipers on various trains would randomly stop working, but that was fixed a while ago. Perhaps this has resurfaced?
