No washer fluid at the blade - solved

[scottf200]

That’s a lot of fixing . Wow the appliqué change?

Do a search for applique in the public service doc list here:

It took 2 hours to get my winter tires installed at Tesla service. When it comes to tire service, Tesla is not Les Schwab. Unfortunately, I was prepared for the wait. It took 1 hour to put the spare in the bed and box with accessories next to it after waiting a month for the appointment to pick up the parts.

Yeah Tesla is not a tire shop and I wonder about the techs sometimes, when I got winter tire package installed I had 5k miles on the truck , the tech didn’t bother to mark tire locations (tires 101) on the take off’s so if there was any uneven wear I wouldn’t know where , also when I go to put them back on in spring can’t mount them in correct rotation

Same condition here. Thanks boys, I’ll take it from here with help from Les Schwab for balancing and the next set of tires. Unfortunately, Les Schwab won’t touch any Tesla for alignments. They inform your need to get Tesla to perform one. +100k on my model 3 - lots of experience with folks not wanting to touch a Tesla.

This was driving me crazy, even after dealer replaced the blade I was still getting minimal, almost no washer fluid.

So I checked the actual hose connection to the blade and the tiny hose was actually kinked inside. The problem was that in my situation it was slightly too long so it was ok when you remove the blade you need some access but if it's too much access when you push the blade back inside the hose had nowhere to go and just kinked because it was slightly too long.
I just pulled it at the base of the arm readjusting it and it fixed the kinked spot.
Now the water goes out like crazy, almost too much water

Took apart mine and it looked like it was kinked. I took the blade off, took off the little clips that holds the fluid tube to the arm, made sure there no slack in tube and it's not kinked, reinstalled everything and still not much fluid spraying out. I'm at loss.

Strange. I am definitely getting much more water after fixing the hose. Suck it didn't work out for you.
The hole blade setup is such a stupid idea. I am wondering if the blade water channel is too small and gets clogged easily. I have a backup blade available. Thinking about completely disassembling it to see how the whole process works. I am sure it's nothing crazy complicated so should be easy to see (hopefully) what's going on.
Wiper pump not strong enough or actual blade is the culprit

Pinholes on my blade aren't clogged, all of them are looking good.
I believe there is more to it, as the front camera washer is spraying a lot of fluid on it. I bet eventually Tesla will come up with separate jets along the blade like on MY wipers.
I think the CT blade design was made by some junior engineer lol.

This begs the question: How much fluid is the CT designed to deliver? Does anyone see a way to run a "piss test"? Something so we could all make the same measurement, and thus diagnose if the hose is kinked, or the holes plugged, or the fluid viscosity too great, or whatever.

Temps are below freezing here, so I am not real anxious to run an experiment, but on the other hand, it seems like almost no fluid is running onto my window.

I tested my washer fluid amount after the service center had the truck. Nothing has changed still have little easer fluid. Notation in service records states that " low amounts of washer fluid onto windshield is under investigation ."

I was thinking about disconnecting the tube from the wiper blade, route it to the side and see how much fluid comes out when it's not connected to the wiper. Maybe I'll do it tomorrow and take a video.

If you do, fill a measuring cup while you time the fill. )))

Ended up taking off the elbow connection at the arm base. While connected a flexible tube to it and running wiper on wash, this is how much water sprayed from two swipes.
In my case there is no pressure at the nozzles and it kind of leaking out rather than sprays.

If anyone wants to do the same and measure pressure or amount of washing fluid, just take off the cap from base of wiper arm and connect any flexible tube with fittings diameter.

 

[PhillyCyberT]

Cool. Will try it too. Same is with my wiper blade the water gets out now but more in a leaking fashion from the small holes not as a spray.
Looks to me that the pump needs to work harder, more pressure needed.
I wonder if this can be just a software change and not a hardware issue.

they should have enlarged the openings of the water jets... needs more fluid each time you push for washer fluid or let the pump run longer...should run as long as you hold the button in

 

[Bobo_LaDouche]

Thank you for confirming the pump delivery volume. We all appreciate this.

1 oz fluid per swipe from the source, that is a lot; the pump motor and pipe capacity seems more than enough, assuming the pressure is designed correctly to reach the top of the blade.

It remains to analyze the holes in the blade to find out why fluid delivery is so low for many of us. It seem likely that slightly enlarging one or two of these holes would give me the performance needed for mud/snow cleaning while driving. This might be difficult to be precise with such tiny holes, given the trade off between spray volume and tank capacity. Now I need a spare blade assembly for some trial and error testing.

PS. If any one else tries this, and has a long clear tube, then hold it vertical to see how high the fluid goes. We can estimate the pressure from this.

I agree if you hold the button it should be continuous flow not intermittent . Maybe software update .
also does one wipe before emits the water which just drags the dry dirt across before the water can do its thing .
