Get some Rain X and treat windshield and wipers with it, smooth action from there on....i use that on all cars, they all do it specially if blades are longWhen my wiper blades are operating in the slow speed setting they seem to jerk and chatter during the wiping action. This is especially evident with the wiper on the left side of the car. Has anyone else noticed this?
There you go. Good call.I live in Georgia and majority of the time park in a garage or in the shade. I do think that the issue probably happened when the car was sitting out in the sun at the dealer because when I took the blades off they seemed really warped and dried out.
