I purchased a '96 CE several months ago. I don't take it out out in the rain much because the windshield wiper blades stutter and occasionally the tips catch and they really bounce around. I've tried many window cleaners, tried Rain-X, replaced the blades (twice) and clay bar'd the windshield. Using the clay bar helped reduce the problem some but didn't fix it. Any suggestions on how to solve this problem?

What kind of blades are you using? I personally never take mine out in the rain, so I replaced them with the stock rubber ones, but you might try silicone ones.

Thanks, I didn't notice those in the Eckler's catalog and purchased the stock rubber ones. I also tried a new pair of AC Delco's from Davie's. I guess I should try one more new pair of the silicone ones.

many of us who have this problem replace the left blade with one an inch shorter

Agree with the 1 inch shorter blade, AND regularly CLEAN each blade's rubber contact that actually touches the windshield.

If you don't clean the contact surface, it tends to "stick" as the arm tries to cycle across the windshield surface.

If you don't shorten at least one of the blades, the first time either one "sticks" to the windshield during cycling, the 2 blades will collide, and one or both gets BENT. Once one or both get bent, they'll never work reliably again.

Wipe both dry blades with Armor All. Let it dry. Then use the wipers on a wet windshield. It not only helps with chatter, but rain just beads up and blows off the windshield after you've done this.
Jim's advice on keeping everything clean also goes a long way towards free-working wipers.

A new windshield and fresh Rain-X blades was miserable to drive.
I left the wipers running while washing the car and soaping the windshield.
Took a few months of this on the DD before the blades and glass settled in.

Thanks for all the good suggestions. As y'all know, in Florida you never know when you could be driving in rain. Hopefully, I'll be following up with a positive result soon.

The problem is the angle at which the blade attacks the windshield. When the wipers are turned off, inner edge of the blade is always facing up. After years of this, the upper edge of the metal arm gets slightly twisted toward the hood. When the wipers are subsequently turned on again, it's like combing one's hair against the grain.

In order to have a smooth wiper the rubber blade MUST be perfectly perpendicular to the glass surface. To return it to the proper angle, place two adjustable wrenches, held a few inches apart on the wiper arm. Then while holding the one closest to the pivot point stable, turn the one closest to the wiper blade slightly toward the windshield.

Lower the wiper and check to see if the blade edge lands perpendicular to the glass surface. Repeat until the blade is perfect. Salt to taste, and you're ready to serve.
