Windscreen question

[Curran]

I know it might be difficult to capture, but can you try get some pictures.

Maybe you need new wiper blades or wiper arms, I'm imagining the wiper isn't contacting the window properly. If you put new blades on and it's still happening try bending the last 1/4 of the wiper arm slightly towards the windscreen which will put more pressure on the wiper pushing it onto the glass a bit more.
