Can anyone help me work out the issue I’m having with my wipers? Every time I use them they just seem to bounce across the windscreen rather than wipe the water away. I thought it may have been the old wipers so put new Mercedes Bosch blades on them. But this still hasn’t fixed it. It’s very annoying and I often avoid using my wipers where possible as the noise is doing my head in. Any help would be appreciated!!
