So in an attempt to delay going to the in laws for christmas day for as long as possible, I thought I'd tackle my blocked passenger washer Jet issue on the E46

Symptoms: 1 or both windscreen washer jets do not work but the headlight washers do. This rules out a clogged filter for the reservoir bottle as nothing would work in that case.

Issue: You have checked for blockages on the water tubes and used a narrow pin to clear the jets themselves but the issue persists.

You have now narrowed the problem to the washer jet enclosure itself.
Inside the washer jet enclosure is a rubber valve that is operated by water pressure against a little spring.

DIY: (be careful as these pieces are all plastic and potentially brittle after many years)

1: Unclip the water hose and electrical heater connection from the washer jet enclosure. You should end up with this piece

2: BE CAREFUL here as there is a small spring inside and once these 2 pieces seperate this spring may go anywhere rendering the washer jet enclosure useless.
Use a wide but narrow flat head screwdriver and insert it between the 2 pieces and twist to unclip the 2 parts - this piece may break, I was lucky in that the plastic bent enough for the 2 bits to be pulled apart *phew*
You should now have seperated this piece from the main body

You can see the rubber seal and the cause of my problem - the orange rubber valve wedged inside! This may be caused by the water in the jets freezing and thawing and dislodging it out of place.

3: I used a pin to carefully pull the valve out. You should now have these 3 bits

4: Here is a picture of all the seperate pieces - including the little spring

5: Reassemble like so

6: And place the little spring over the orange valve

7: Now while holding all this upright, carefully lower the main enclosure bit over this and snap it all back in place - making sure the spring is centered.

8: Fit it all back to the car and enjoy working washer jets :D

Hope this helps anyone with the same issue - must go get ready now as the missus is jumping up and down at me :eek:
 
The more common issue is that the pipes leading to the washer jets become very brittle with age and crack - so check for this as well.

Some Halfords washer tubing will fix that particular issue :)
 
BEST DECEMBER 25TH POST EVER!!!

Mad props to you :)

Also, buy washer tubing? no no no, every man should have something suitable in his shed, or just steal some from the scrapyard next time he's there, I've fixed 2 cars with the later method :)
 
just fixed my washer jet... couldn't figure out where the little rubber valve was meant to sit, so your pics were spot on - cheers
 
Oddly, the first split second of jet hits the middle of my window, then it kind of dribbles out just above the wiper line there after, light jets are as powerful as ever(they clean the car at the time same time it seems)

They are on a totally different circuit.
