Windshield Washer Fluid leak

[89Suburban]

Definitely use some mini zip ties to cinch those hoses down over the fitting barbs guys/gals. This crazy this is an issue on a 2 year old vehicle!

Hi
This is happening to my 2021 model. I have traced the lines and tested for fluid flow to the connection above the battery. It is good. My rear is not spraying at all. I checked the connections under the right-side rear and under the rear headliner and they are connected. I am going to separate the hose above the headliner and see if fluid is reaching this point. If not, it has to be the nozzle or where the hose is attached to the nozzle or I am missing where a hose connection is. Feel free to chime in if you guys know something I don't!! Now I just have to figure out how to access the nozzle area.

See my post. Behind right rear side trim.

There's a connection inside the cabin just as the hose comes inside. You'll need to remove the rear floor storage console, D-Pillar trim and rear sidewall trim to see it. It's this connection point circled in the picture. If that is leaking, then the area under the floor storage is probably filling up with washer fluid and hence you can't find the leak.

Found same thing on my 22 Yukon xl Denali. I had removed both front tires and inner fender liners looking for the leak. Now to get my carpet dried out!

Hello new to the forum, late to the party!
We have a 2021 Yukon, took it to the dealer because of the same washer fluid issue y’all have. They filled it, nothing happened.
But, they had to drive it for another issue I’m having with the drive train. Came back, tank was empty. They told us they’d have to take the dash apart. Huh?
We couldn’t leave it all day, so brought it home.
Guess what the floor in between 2nd & 3rd row is wet. Thanks to this thread, my husband has a starting point to fix it ourselves( hopefully).
She is going back on 9/23 for the drive train issue to be fixed.

You may want to look for a different Dealer.

Have your husband review this thread - https://www.tahoeyukonforum.com/thr...-rear-washer-fluid-not-spraying-fixed.147800/

I'll also add that when you find the hose that is disconnected, put a zip-tie around it at the connection point. Just a little extra clamp force at the connection will ensure it never happens again.
