Hello hummer experts
any idea replace my rear wiper blade with PIA Blades still doesn't solve the problem of not touching half of the glass, I replace the Arm also and still the same problem. Any idea?
I did bent the blade just a little bit and it's seems went worst.

 

Lube it real good where the arm pivots by the base.

 

I'll try that thank you.

 

You put a brand new wiper arm on and it still doesn't touch the glass ? You bent the new arm?
