Default Weak windshield wash spray/passenger side/2017 RX

I've blown air, switched nozzles w new,swapped the driver to the passenger side,
the passenger side spray is just much weaker, any suggestions? The rear is good pressure as well

Maybe a clogged or broken tee, or that side hose has a hole leaking out when you use it. Or is getting pinched/collapsed but only when the hood is closed.

I would take it all out, which it sounds like you did, but I'd do it again looking for what I missed.

I didn't see any drip/fluid underneath, so I ordered a check valve where the 2 washer nozzles attach to. Had to pop off that black fiber insulation panel , and ordered new push pins too: they snap when you pop them off with a molding tool . I'll reply if this fix works

Default Windshield washer passenger side weak

I changed the check valve under the black sound insulation under hood, and it's good again.
the check valve is a black 3 prong /hose attach points .
so, about 20$ fix( the check valve 8$, and the new push pins package of 10, $12)
imagine at dealer this would be hour labor charge/$125, plus marked up parts 🙄
