I have always had an issue with my '03 Grand Cherokee driver side windshield wiper that i attributed to the windshield washer jet not spraying at the lower part of the blade (towards the pivot end) not cleaning the windshield well. Had been planning on trying to adjust the spray on the jet but made a major discovery the other day. Have high end blades on there and looked where the blade contacts the windshield and noticed that the blade doesn't even contact the windshield towards the bottom of the arm, there's several inches that are up off the glass.
Since it's done this with many sets of blades I am assuming none of them have wiped well. So the question is what is the cause? The spring pulling the arm down? Maybe a bent arm? Would really REALLY like to resolve this issue since I live in Florida and only use my wipers occasionally.... like maybe just a dozen times a DAY :O)
Thanks!
