Hopefully this is a simple question with a simple solution.
The washer jets on the “new” Jazz simply squirt out a linear stream of water and don’t spray the screen like the “old” car.
The new Jazz is a 2006 model (56 plate) if that makes any difference?
I can normally clean out the washer jets with a pin or a needle but didn’t have much luck doing that with this car.
Is there a different technique involved with the later version of this model?
-
I changed the spray heads my Civic from big spray to double nozzles that only gave a single stream out of each nozzle because the big spray was emptying the washer bottle too quickly. Original Jazz did have spray but think they went to jets on later ones. If you use tap water in washer bottle and live in a hard water area the nozzles can block with limescale just like the showerhead spray on a bathroom shower, maybe a bit of mild descaler like vinegar in the water may help, window cleaners put vinegar in their water to stop limescale streaks on window glass.
The wide spray nozzles have a slot across them, the single stream have round hole.

My 56 plate has a very fine, wide spray on the windscreen, but the rear screen is a linear stream.

Sorry for the tardy update.
Tried the washers in the car yesterday and the drivers side was almost spraying as it should.
Tried covering one side at a time to increase the pressure and this did appear to help slightly. Still not exactly spraying per the '02 model but acceptable.
Got in the car this afternoon and it's back to the meagre stream again! :-\

Yes, these are the wide spray nozzles according to your description.

Well the car still has crappy washer jet output...
Went straight through the MoT on Friday, after digging it out of a snow drift it was sitting in for about 4 days, can't grumble about that.
Was thinking about ordering a couple of these extortionately priced replacements...

May or may not be relevant but when i took my jazz in for its first service last September the dealer said that the washer jets were "sluggish".
It seems that Honda screen wash does not mix well with some other makes of screen wash and turns the whole reservoir to a jelly like consistency.
The dealer kindly offered to flush out the system for about £180 but i politely declined, emptied the reservoir, washed it through with hot water and refilled with Halfords special (£4 for 5 litres) and its been fine ever since.
Just remember at the next service.
-
Experience has shown that ordinary tap water and some propriety windscreen wash products do not mix well. In my case it developed a cats pee smell and produced a black sludge in the reservoir.
I now use di ionised water and Autoglym and have not had a repeat. I know, some do not like diionised water but I have had no problems with this mix. Incidentally, the reservoir/jets did not freeze despite being down to -6 c.

The stuff I have in at the moment smells like bubble gum! ;)

I use concentrated Clearalex solution. No water at all.

De-Ionized water is fine with plastic, but not so good if you have any copper based alloys 'yellow metal' in the system (brass, bronze etc.) My wife rarely uses her windscreen washers and the fluid in the system gets a bad smell, and the screen gets smeary (I know how much is required to top it up as only I do it, she says she does not use it because it smells bad, I tell her if she used washers more often then fluid would not start to ferment and get the bad smell, but logic has never worked with a female). I have completely emptied her Jazz bottle a few times and refilled it with fresh so it smells nice, but she is not about to change her habits.
I use the same stuff but have to fill mine up every couple of weeks and it smells fine, if I use concentrated I only use tap water, but normally in winter I do get ready mixed so I am sure concentration is correct to stop it freezing.
-
I top mine up every Saturday, when we return from our hike to see mother-in-law. I use the washers a lot, especially when on dual carriageways. We went over last Monday, and being a week day the traffic was mainly trucks, so I used a wheen of Clearalex then.
-
I don't know whether they still sell it but my mate in the local garage used to add some additive to the washer bottle when he did services. Produced a fresh Apple smell, overcame the normal smell you get sometimes. Worth a try auntyneddy.
-
Thanks for the suggestion MikeG1944 but since I changed to Dionised water and Autoglym I have not had any smells.
I use quite a bit of washer fluid and so he bottle gets topped up weekly.
Not quite on subject but recently when we had the fog, I was surprised that I was the only one using my wipers and washers. Something I was taught, it is amazing how much muck is in fog.
-
I use Halfords ready mix blue screen wash. Works a treat and didn't freeze when the Beast from the East paid a visit!

Indeed.
Mind you, you have to be thankful when they use headlights in fog these days.

I can remember how dirty 'smog' (smoke and fog) used to be, my face used to be proper dirty on motorbike. But fog is just water droplets (low cloud) and not at all dirty. Using headlights in fog can actually reduce your forward visibility as the light just gets diffused an reflected straight back at you by the water droplets, it is why foglights are mounted low down, there is a clear area just above the road - if you can shine the light forward in the clear area it is not diffused and reflected by the fog so much.

Well I've just been out for another look at the jets.
Lots of water coming through them but only going roughly 10" up the windscreen, not in a spray pattern just a simple "straw" of water coming out..
Both jets are doing exactly the same thing.
If I block one of the jets up, the other one does indeed squirt out as per expectations. Same blocking the other jet up!
So if the water is streaming through OK and the blocking off of the other jet produces the correct spray pattern, this might suggest a lack of pressure at the jets?
Where should one look to improve the pressure/flow of the system?

Could have a kink in the tube from pump to jets.
Sediment in washer bottle blocking pump inlet
Pump may be on the way out or getting sticky - they are only simple little motors, commutator brushes worn or damaged, impeller may be breaking up and restricting pump volume.
Both the front and rear pumps are on drivers side behind the front end of the wheel arch underguarding, if you are going in there may suggest you replace headlight bulb at same time :o

Sounds like it could be quite a bit of effort then!
It doesn't look like the jets are that easy to remove either.

Well I think this problem may have been solved, using a very old solution (pun intended). ;D
Back in the day, washer bottles were filled up with water and a bit of washing up liquid. At some point, decades ago, after washing cars for years with washing up liquid, some bright spark pointed out that it contains salt and should not be used.
On a whim, after finding that my purpose made screen wash was actually pretty sh1t at cleaning the windows I decided to try adding a small drop off washing up liquid to reduce smearing.
It worked a treat!
Decided to put some into the GF's Jazz as we both use the same screen wash...
After one tank of screen wash and washing up liquid the washer jets are working as per Honda design
Coincidence?
I suspect not!
-
Seemingly Fairy doesn't contain salt.

I think it was the Aldi washing up liquid but will check :D
