Wiper blade gap

I’ve tried various non OEM wipers and most of the blades (Bosch, Trico, RainX) on the passenger side don’t make full contact with the windshield.
There’s usually a 5 inch gap in the center; the curvature of the blade is more than the windshield.

Can this be fixed somehow by adjusting the tension of the arm or by any other means?

Mine doesn't do that at all. I know that there's some sort of cover that clips on to the base of the arm, not sure if it's on the pass. or drivers side though. I thought it was simply cosmetic, but maybe serves more of a function that I thought?
Only other thing I could imagine is a replacement windshield with a deformity?

IgnorePluto . He is a troll.

If you have already tried replacing the wiper blades, the following are known solutions.


1. Bend the wiper arm in hhe direction of the windshield so the optimum contact angle is reached. Play around with Bending it so that you can see what angle is desired.

2. Sometimes a new windshield is in order. Mine was so pitted....only replacement ended up working for me.

This worked like a charm. Should have thought about it.
Thanks!

A troll with 11k+ posts? I dunno what the admins are doing on this site, but if they can see past Pluto and Diabolis and do nothing, then the fact they're not being paid to "take care" of this site is justified.

Nice call on the wiper arm bending, btw. It is true, the simplest solution is usually the best solution.

I see peter is still feeling a little inadequate.
