2016 Kia Sportage rear washer jet blocking

Never done one on that car , but on similar setups there are often rubber grommets inside tailgate that on removal give access to retaining screws / nuts .

There are grommets - one for the rear brake light cable and one for the washer. hose . When the washer grommet is removed all it does is to let you see the hose. there is barely enough room to put a finger in. You can't reach the jet from the grommet hole. I suppose I'll have to take it to A Kia dealer and pay the price!! Thanks anyway.

Have you tried blowing through with compressed air or small needle to clear the jet before stripping anything ,just a thought also watch the hose has not come off at another union even inside the car

The position and shape of the washer jet is such that I find it impossible to see the exit hole when the hatch is closed. It's even more difficult to see or even feel the the hole when the hatch is in its fully open position. I know that the hose hasn't detached elsewhere as the blockage can be temporarily cleared by moving the open hatch up and down several times after which the washer works normally for a short time. It's as if there's something floating about in the hose.If you can think of anything i could do, I would appreciate it.
Thanks.

Check washer pipe in trunking between tail gate and body sounds like it is kinked hence it sometimes works if it is get some washer tubing and plastic connectors and repair pipe no need to remove panel or jet

Sounds like that could be the source of the problem - I never thought of that. I'll check it out.
Thanks.

I think it was the non return valve that was giving the trouble , silting up . Replacing with straight through or removing the inners apparently fixed it .But you still have to reach it !

Yeah, that's the real problem!! If you find out how, please let me know!!

This shows you .

Thanks for all your hard work. I thought that removing the trim panel would allow access., but I wasn't sure if it could be safely detached. I'll try to remove it and take it from there.
Thanks again

Got there eventually !!
