Slo-mo video of chattering wiper

[gillmj24]

When I took delivery last October one small issue I saw was the driver wiper skipping and a hazy spot on the windshield. Okay no big deal, get home, use some glass cleaner and buy a brand new Bosch expensive wiper. But the behavior is the same, the bottom of it vibrates back and forth no matter how clean and wet the windshield is.

Looks like I can't upload a video here, I'll try uploading elsewhere and posting the link to it.

I'm not good at youtube yet but try this....

Sometimes that can be caused by a twist in the wiper blade arm so the wiper blade is not perpendicular to the glass. I had that issue on previous cars and used wrenches with protection on the arms to twist them the other direction.

Did you use a glass scrubber/polish? That's what it took to fix mine. Just some cheaper glass stripper from Walmart and some elbow grease. Got worse when using Michelin wipers that had rain-x like coating that stayed on the windshield. I'm sticking to Trico now

Hello ! I had the same problem for years and the Tesla Service Center could never resolve it. I have a 2015 Model S and replaced the blades several times to no avail. I have used just about every type of window kit with little success until recently. I purchased the Cerakote Rapid Ceramic Glass Coat Windshield Kit from Amazon for about $ 17.00. Watch the youtube video on this product. This is the first time in years that my wiper blades don't chatter ! I currently use the Bosch "ICON" wiper blades and for the last 2 months, the chattering has virtually disappeared ! Cerakote also sells one of the best headlight restorer kits in the market place. I'd like to mention that their customer service is second to none ! Please give them a try

Never heard of the twist. Interesting. Mine are horrible. Just replaced the blades and it didn't help. It's actually embarrassing when I have people in the car with me in the rain. I've had a couple M3 loaners and the wipers on those were completely silent. The two things that suck on my MS are the wipers and headlights.. Anywyay, I wonder how that huge Cybertruck blade is going to be? LOL

It's only the bottom of the driver side blade for me. I'll try the glass polish fix before resorting to lock wrenches

Passenger side in the foreground. No chatter or skipping.

Drivers side. Tried to get it in the pic but the post above is on to something. It looks like the angle of the wiper arm in the "twist" direction is different from driver to passenger side. Rubber not hitting perpendicular. How much force to twist with before you break it, and how much does a new wiper arm cost?

My issue was a bit different. I didn't have skipping chatter so much as the bottom of the blade flopping like in your video but hitting the metal wiper arm and making noise that way.

What worked for me was swapping my driver's side wiper blade to one that was 2" shorter. The shorter length seems to make the overall blade assembly a bit stiffer so the bottom doesn't flop and the decrease in size doesn't have a noticeable effect on how much windshield it wipes as you're only losing an inch on either end.

Again, my issue was different than yours but it's similar and my fix might work for you.

Thanks Shiro. I put another layer of glass polish this morning since the first coat didn't do much of anything.

Bought Kimblade wipers from EVannex. No chatter and no twisting the arms necessary.

Over time even the small passenger side started chattering.

It sounds like your wiper mechanism is worn and on the way out, check for the infamous hood scrape notch.

Windshield wiper arm scraping metal under the hood

Hi, just wanted to hear opinions on this wear. Seems the wiper arm is bending to far upwards and scraping the hood as it passes. Any known remedies? Only other mention of this i can find is two years back in this section of the forum. Regards - Robert

I'm good, no evidence of scraping.
