It seems like the passenger side on my tC is not being pushed against the windshield enough because every time it snows it doesn't wipe at all. It just makes 2 lines with the 2 ends. Is there a way to adjust that? Or to make the arm push the blade against windshield a little more?

 

you could try getting a fresh set of blades, that might work,

 

That was the first thing I did. The blades are only a week old.

 

Clean off the blades with newspaper. My wipers were still working like new after 3 years...even including 18 months of not getting any water on them (usually they dry rot).
