Hood down in light rain there is as much muck on the inside of the screen as the outside...so wipers don't help much...
Hood up 2 of the three wipers work very well.
But swapping the blades around changes nothing, the drivers wiper never properly clears the glass.
The navigator always has a clear, none smeary, view.
You've just reminded me of my second car which was a Vauxhall Nova where the drivers side wiper kept breaking
It was never the passenger wiper but always the bloody drivers side that came unattached which was coming off a pivoting arm assembly
I could never understand why the engineers made the drivers side more prone to breakage!
Used to drive me nuts
