Windshield washer jets - they are adjustable!!!

A lesson in faith.

I went out and puttered with Marlene this evening...on the list was taking care of one of the things she's needed since we first met - fixing the windshield washers.

Oh yeah, the one on the right side worked fine but the left was MIA, gushing fluid from the hood/cowl junction and generally being useless.

So, I re-plumbed everthing on the hood and Shazam! Working washers...except they are aimed too high and might really strike the windshield of the car behind you in traffic.

I say to myself, "Surely, the fine engineers at MB don't really expect me to be driving so fast that the washer fluid would be forced onto the windshield by the blast of air coming over the hood at autobahn-like speeds."

"No," I think, "This component is just like every other facet of this vehicle: it has to be adjustable!"

And fellow forumites, the jets are adjustable!!

The jets are actually metal orifices which are pressed into the plastic jet housing that is on the hood. They can be re-aimed if necessary. I used a very small drill bit (#64 or so) as a mandrel, placing the blank end of the drill into the mis-aimed jet's orifice and gently moving the orifice in the direction necessary to get the fluid stream to hit the desired point on the windshield. It might take a couple of tries but believe me, those jets can be aimed.

Proof once again that Mercedes Benz is "Engineered like no other car in the world."

R Leo, every car I've ever seen or heard of has had adjustable washer jets. Use a pin to adjust them carefully, because one small move will make a great swing in water flow.

I like to use this


I like to use a drill to make sure all the crud that builds up is out of the nozzle, and then I adjust it with that tool, and its always fun to aim them toward other cars, but people really dont like that for some reason. I used to use pink deicing fluid, but it stains white paint. =)

You never saw my Blazer...

Randall ,
The Blazer that I also own has a cheap plastic nozzle...spray adjustment is made by BENDING the metal cowl piece that it is mounted on...

I expect little else from Detroit.

Hazet also makes a specialty tool to aim the nozzles. It is telescopic, so that you can see where the stream will hit the windshield. I've seen them on ebay for about $13.00, plus shipping. I'm not sure that I need one since I aim them maybe once every couple of years.

Hey thanks. After cleaning the plugged crud out of the
passenger side nozzle it was squirting over the roof.
So I've been lightly tapping the blinker stalk to get some
washer fluid on that side. I'll try adjusting it.
