Recently on 5/16/26 I went to my mechanic and had my kia pen wipers replaced with brand new Bosch evolutions. Noticed it glides smoothly when wiper fluid squirted and clears in one swift stroke without leaving any streaks which is good. However I noticed when I pour water on the windhshield and run it a few times on different speeds it chatters, is this normal? Thanks

Update I think it just wasn’t wet enough because during a rain downpour they moved swiftly with no noise, brand new Bosch evolutions. So does it just boil down to if u run it too many strokes and windshield is semi dry it’ll chatter ?

Nope, the wiper need to be aligned, please watch the video to see what I am talking about. If this is not correct the wiper will chatter no matter what.
