Do your windshield wipers shimmy when they move?

Mine do not make a smooth sweep across the windshield. They move with all that I can describe as a shimmy. What causes this? Too much tension on the windshield or not enough? Or is it just the motor itself. No other car I've been in does this.

What kind of blades are you using, and how old are they? Does the shimmy make noise? Does it happen in the wet or dry?

I've had this happen when hand held spray-type car wax (ex: Turtlewax Ice) gets on the windshield. To get wax off, one solution I've heard & used is to apply a non abrasive household cleanser (Ex: Bonami) to the glass and rinse thoroughly.

I agree with Dave, I've had this happen when the windshield and wipers get dirty with "invisible" dirt, road slime or whatever.
I've used a mild abrasive household cleaner (damp, on a sponge) to clean the glass and replaced the wiper blades at the same time.
Then clean again with a good glass cleaner such as Invisible Glass Cleaner and use newspaper to wipe with. Leaves no streaks.
That has solved my problem with jumping, jerking wiper blades.

1 part tap water and 1 part denatured alcohol is VERY good for a nonabrasive window cleaner.

Mine did that too. I thot it was cuz the way the blade sits in the rest position. I replaced them and problem solved

Ahhhhh.. So my problem might be that one wiper was replaced and the other one is old? Let me replace the other and clean the windshield to see if this goes away. Thanks for the suggestions.

i use, 0000steel wool. it works great. spritz on some window cleaner and wipe away years of invisible crap with no scratches. but go light.

My wipers hop a little bit, I blame the Rain-X I use, but I'll keep using it. The advantages of Rain-X far outweigh the annoyance of 'hopping' wipers.

mine hop some, even with brand new wipers (the new design too). i dont really even need the wipers with all the rain-x i have though. even in the heaviest downpour i can have the wipers on low and see just fine.
