Windshile wiper holes for the washer fluid. Why are they evenly spaced?

[stevem]

Going into the second winter with the Cybertruck. Still love it, but these days in the NE of the USA, lots of road grime and salt and winter weather, makes me think of this again. Why does the washer squirter for the washer fluid so terrible? And why are the holes on the wiper blade evenly spaced along the length of the wiper blade.

I know they changed the software so that after 3 wipes the washer pump never stops. But shouldn't the blade be changed so there are more holes closer together on the upper portion? The lower edge of the wiper blade moves 1 foot. The upper edge moves 8 feet across the window. Shouldn't more fluid get applied to the part of the window where the wiper moves the furthest and the fastest?

Half the fluid goes into the green section and half in the red

It's really difficult to clean the passenger side of the glass and the upper passenger side especially. The driver lower portion seems to get way too much washer fluid.

This seems to be something that could be easily fixed by making a different wiper blade with the holes a little further spaced towards the bottom and closer together at the top.

Looks like yours is just dribbling at the top, can be caused by a separated wiper tube. Look half way on the wiper and see if there’s a gap where it’s leaking out.

Yeah, it's already been in for service and that's not the case. Double checked when I got it back too, along with measuring the fluid that comes out of the top half and the bottom half during a cycle. Same amount.

The wiping motion forces more liquid already sprayed to the outside / passenger side of the wiper. Mine did this and it was becuase the fluid tube wasn’t fully attached, squeezing the top and bottom half together fixed it for me. Now I notice the rubber likes to wiggle down twords the drivers side and flops in the wind, I had to manually slid that up every few days. It’s time for a new blade.

Mine is doing the same thing. Its interesting that it streams fluid instead of spraying like every other wiper system. Funny enough the lanes where the spray comes out are perfectly clean, but between where the nozzles are is streaky and don't get clean. Ive cleaned my wiper and windshield and it comes right back

Yeah, it's bad. The fluid distribution is uneven. less at the top of the blade, with reduced pressure on the glass there, and the blade's top covers significantly more distance and area in the same time as the bottom. I like your idea of getting more fluid to the top somehow, or adding more holes. I wonder if it's possible to drill extra ones?

On the highway, I overuse the fluid to compensate, but it runs down the side windows, covering the whole truck in streaks. Then the reservoir empties out fast. On the bright side, this is the first truck I've owned that can take an entire new gallon of fluid without leaving any in the bottle.

With the current hole spacing, the fluid needs more time to spread across the glass to be effective. Every other vehicle I've had addresses this by letting you spray separately from the wiper function.

To clean a salty mess off the windshield, you need to move the wipers while it's wet. otherwise, you'll just create streaks again if you wipe on a dry surface. As you all know, at highway speeds, the CT holds the wiper at the bottom of the windshield and waits a bit to let excess fluid blow off before lifting it back to park. This delay always results in a smearing, dry wipe.

Driving with limited visibility at highway speed, trying to time the spray and wiper button presses like I'm playing Donkey Kong—just to keep my side clean—still ends up looking like Missile Command on a blurry CRT after the blade parks.

Maybe the CT could spray more like a normal car. Here's how it could work: When you press the spray button, the wiper first moves to the bottom, positioning the nozzles like on a typical car to spray upward onto the windshield without wiping. Upon release, it stops spraying and wipes a couple of times, without pausing at the bottom.

For a DIY fix, I've contemplated removing the spray tubes from the wiper and mounting a fixed nozzle with an adjustable spray pattern, then tweaking it to cover the full windshield.

Compounding this is the frequent absence of window washing amenities at superchargers. Even when co-located with a gas station, we are frequently forced to walk 100 feet or more to 'borrow' a washer wand from a gas pump. When co-located at a Wendys, this isn't even an option.

I need to remember to put this in my review of the supercharger...

Biggest weakness of the CT- The comically bad wiper system. All it needs is a delay after spraying the wiper fluid to let it touch the glass before wiping. Hope they can figure this out with a software update because I'm using like four times the amount of wiper fluid that I normally would use and still not getting a streak free windshield.

Spray from the driver's side gets pushed up the blade towards the passenger's side of the blade (when it's horizontal is how I define driver's and passenger's sides). However, if it were the case that we needed more flow to the passenger side, rather than drill new holes, enlarging the holes as they get farther away from the pivot point would "evenly distribute" the fluid.

As the wiper wipes, the fluid is pushed towards the wiper tip so it actually needs more fluid at the pivot point because that part of the blade doesn't inherit fluid from any other nozzle.

It would be nice if when you first hit the washer button, a nozzle located at the pivot point would spray out across the windshield in a fan pattern. This way, there wouldn't be a first dry wipe and it should be simple enough to retrofit.

Tesla could make a software change to delay the wiper to allow the new pivot point nozzle to spray first.

How much could a nozzle cost? Everyone here would probably pay for a better wiping solution.

Heck, someone here could probably design a snap-on 3D printed nozzle to solve the problem. If it weren't so cold out here, I'd look into doing that myself.

Definitely could snap on the the cantrail and hold a y splitter and two adjustable nozzles. All that can be purchased at AutoZone. It would be awesome if you designed the clip!

I was thinking about connecting it to the wiper arm and using a T connection with the current line but I'm not sure if a constant spray would work or if the spray would be best if it was just a spritz and then the normal ones took over.

From a DIY perspective, we can't control the pump, or when it activates, so yeah, it would be a roll of the dice to see if the current pump pattern would be effective in this setup. It would be a fun project to try though if I had a little more 3d modeling experience! I think you could tinker without damaging the original setup.
