Windshield washer sprayer adjustment?

[MurphyMurph]

Question: Do your washer fluid sprayers cover the entire windshield or just the lower half?

Even when stopped with no wind mine don’t reach the top portion of the windshield.

Is there any adjustment to the sprayers?

If you do a search there is a thread covering this issue

Yes I have searched and read through the other couple threads but they are related to issues with the sprayer not working. Mine work, the sprayer nozzles are just angled too far down so they only hit the bottom half of the window. As a temp fix I wedged a couple pieces of black zip tie under the edge closest to the windshield, but that’s by no means a permanent fix.

I searched as well and could not find a reference to your issue either.

Yea mine does the same thing, drivers side worse. I asked dealership about it and they said not adjustment…. Any help appreciated!

Use a trim tool and wedge/angle it up. Then don’t look at it. This works and I copied this from a 2024 courtesy vehicle I loaned.
Proper fix is to buy adjustable jets or by placing some sort of angled spacer beneath it.

Where do you buy adjustable jets from?

Sorry I’ve not looked into it yet, just wedged mine up (works fine for now). They look generic, look on eBay, and they do sell the adjustable ones with the pin in the middle but I do wonder why modern cars don’t use these any more, maybe because of blockages.

That’s what I was expecting the Grenadier to have. My 80 and 100 series Land Cruisers both did and it was nice to be able to adjust them. They were 2 and 3 nozzle style, both the fan pattern, so maybe those just don’t come in an adjustable type. They’re heated so I would expect you can’t just swap any old sprayer nozzle in.

Has anyone swapped out theirs yet?

Oddly enough, my sprayers went from covering just the bottom of the windshield to the whole surface for no apparent reason. Not long after, the wiper fluid low warning popped up so I topped off the fluid. The sprayers went back to covering the lower portion of the windshield. I wonder if the pump needs air space to build up pressure inside the tank.

You could test this theory by leaving the reservoir filler cap off and see if there's any difference in the pump's performance.
I had assumed the pump operated by "pushing" fluid through the tubing and therefore, being located at the base of the reservoir was self priming and that the weight of the fluid above it would assist its performance...
Another mysterious Grenadier quirk !

I concur with your observations. Ihave noted how warm the washer fluid gets. The very small pressure valve in the cap appears to be to let air in as the fluid drains down not let pressure out. If this valve shuts as the pressure builds up with the heat, then indeed the bigger the air spare the slightly higher pressure the pump will have.

I downloaded the Doga catalogue yesterday and I’ve been trying to identify the parts on the Grenadier. Without taking the lights and fender out to see. So far the nozzle is heated not the water. Don’t know why? in case it gets blocked and frozen up. I took out my nozzle today and identified the wire harness. I pushed it back in and using a trim tool I pry it back open on the top and left it at angle (not fully pushed back in).

The pump I think is rated at Ip67 and it contains a small filter on the inlet pipe. If this gets blocked from debris then this may explain the low pressure hence why the spray pattern is like me having a p*iss in the toilet and leaking everywhere.

I want to take it out and clean it or take the filter out to see if it makes a difference.
