Washer fluid not spraying properly after new wiper blade

[JerseyMike]

I just installed a tesla OEM wiper blade (first replacement)
I removed and reconnected the washer fluid hose as in videos on YouTube and wiper is good but spray does not flow through wiper blade (it spills out near the middle connection)….I checked and it is fully connected so not sure why it isn’t working right.

any tips?

if you've confirmed no pinches or kinks in the hose and that the connection is tight on there, then you can check the spray nozzles for clogs. I personally wouldnt recommend putting anything in the nozzles themselves. If tesla did the replacement, ask them to evaluate it for defective wiper blade.

Hi JerseyMike,
I have been fighting with this on my truck…
At the area where the wiper plugs in, there is a
3” piece of the hose and below this is a fitting that could be a check valve or a filter.
It has arrows that point the flow direction.
I took this out of the line and blew it out with compressed air. Maybe a bug or gel ball blew
out…
Mine flows freely now…
Good luck,
Shawn

I was thinking that, the check valve I didn't touch but wondering if I need to blow it out....I also wonder if I just need everything to prime better...will play around with it

Check for a kink in the hose. When replacing the blade you need to pull some slack in the hose. If you don't pull that extra slack back towards the wiper motor end after replacing the blade and reconnecting the hose it can make a kink and blockage.

Yes, exactly what I noticed happened to mine when I tested post new blade install. It was leaking the fluid from where the arm connects at the bottom of the windshield down into the frunk tunnel and onto the front bumper and tire. Upon examining, I saw the hose kinked up near where the hose is connected to the blade. That needed to be straightened out and pull back toward the lower windshield. to make it one line. The spray doesn't spray way out now, though, only a few inches in front of the blade when using it. I think before it may have sprayed further or I didn't notice?

working now and 2 things were causing the issue...
1. I was almost out of washer fluid

2. I did have to pull back the line a bit as it was bunching up by the check valve

thanks for all the help
