Are you sure it is getting a flow through the pipe. It sounds like you have
done what was needed. (Drill seems a bit over the top)

FWIW I have a small collection of 'wires' cut from old guitar strings when
trying to clear blockages like this. You then have a variety of diameters, and
the wound surface on the larger diameter strings is good to abrade the inside
surface.

+1 as you've removed the jet, can you check there's a good flow
out the pipe? If not and the pumps working, there's a
leak...

+1.

Often, the root cause is a gelatinous "blob" of fungus/algae/bacteria
inside the body of the jet behind the actual pinhole. This is why
clearing the jet with wire or a micro-drill doesn't always work.

Provided you can remove the jet to get at the backside you can often
pull this gloop out from that side. Sometimes it can be pushed through
with "guitar string" from the jet side but sometimes the geometry is
unfavourable.

Obviously, check that you have a good flow through the disconnected pipe
too.

Check the pipe isnt €˜nipped somewhere. I had a CRV an one of the (front)
jets was prone to not working- the only fault I recall having with the car.
The pipe tended to move and wedge itself under the plastic trim bit,
restricting the flow. Eventually I managed to secure it so it didnt move.

Also, our Smart rear jet didnt work. A joint in the pipe run had come
adrift - fortunately it was accessible.

If you are sure it is the jet, replacements arent expensive- many are
fairly generic. Try Halfords.

Good point. The pumps do jamb. You can sometimes get them apart and clean
them. If not an it has jammed in the right position- so water can flow but
not pump- you can fit a generic pump from Halfords in the pipe and connect
the wires to it. I did the to my wifes old Mk1 Panda when I couldnt get a
Fiat pump.

Is the jet on the roof or tailgate? On my car it's in the tailgate. And
the pipe to that via the hinges has a habit of flattening.

Brilliant. Thank you, I'll try that. Son is a guitar fanatic, so will
doubtless have old strings lying around.

For the avoidance of doubt, yes, there is a good flow of water, just not
through the final jet. The rear wiper had broken, so I removed and
repaired, and tested without replacing the cap over the spindle. Flicked
the switch and was amazed to see a jet of water shoot out. Not being a
top of the range model, I had always assumed a washer was not fitted at
the rear. Now I know it is there, I'll try the guitar spring trick.

The drill I tried was very tiny - probably less diameter than the
average sewing needle.

Now you've softened it, perhaps a bit of added pressure or suction

Job done! I think sitting in hot soapy water softened it, and a
combination of guitar string, contact cleaner and a can of compressed
air finished the job. Delighted :-)

Had a similar problem many years ago. I used to top up the washer bottle
from a kettle. The kettle needed descaling and bits of sediments were being
introduced into the washer bottle.
Lesson learnt.

If you have a syringe, attach a short section of flexible tubing
to the syringe nozzle and try and back flush the car jet.

If you can get at the rear of the car jet and remove the tubing,
even better because you can isolate the blockage to be car jet
or tubing.

Given that its likely to be the gel that can form in the
washer bottle, I'd try neat bleach, soak it in a cup of that.

Remove the pipe from the jet and make sure there is good flow out of
the pipe. Sometimes there is a sort of jelly like substance which grows
in pipes, blocking jets. Easy way to clear them is with compressed are,
blown in from jet end of pipe, towards the bottle, making sure there
isn't a one way valve in the system.

The problem, now cleared, was not the jets. No idea whether they're all
the same, but on this car, the water comes through a hole in the wiper
spindle, to be met with a cap which turns the water through 90 degrees,
and directs it through two jets. The blockage was within the cap,
before the jets, and whatever it was, was solid. Softened by running
through the dishwasher, then soaking for hours in a cup of hot water
with washing powder. Much squirting of contact cleaner (which may or
may not have helped), poking with a tiny screwdriver and old guitar
strings and blasts from a compressed air aerosol. Now working
perfectly.

Thanks, yes probably the jelly like substance. It can be quite
difficult to clear out.
