156 Windscreen Wipers Shudder
First post for me, I have just bought a 2005 Alfa 156 and I got it with bad wiper blades because they shuddered across the windscreen, so I replaced with new wiper blades and thought it fixed the issue, but the wipers continued to shudder. So I replaced the wipers again with the modern flexible wipers and they stopped shuddering on the passanger side but the drivers side continued. I have bent the arms to try and make the blades have better contact with windscreen but still no luck.
I have spoken to some alfa mechanics and they say it could be the windscreen or the windscreen motor. A replacement windscreen or windscreen motor will be costly.
Has anyone else had a similar issues and know how to fix it.
