Problem with windscreen washer jets

When I use the windscreen washer jets the fluid flow is very weak. I have had this problem before and it was fixed under warranty but now the car is out of warranty. I recall them saying something about a blocked filter but I'm not so sure because it would be very difficult for debris to get into the washer fluid system. Recently it stopped working completely so I thought the washer fluid tank was empty so I filled it up but the tank wasn't empty. After pressing the washer fluid button for a while it started to work but only very weakly with most of the fluid dribbling over the bonet.
Has anyone else had this problem before and does anyone know how to resolve this problem?
Or does anyone know how to access the filter for the washer fluid system?

The pump/filer gets clogged and is easy to clean out. When this happened to me, both jets operated the same - barely a trickle was coming out of them. If you have one jet that is good and one that is bad, I would think it was the jet that is clogged.
To clean the pump/filter will take less than a half hour. After you do it once, about 15 minutes.
The pump/bottle is located on the drivers side front. You can pull the pump out of the bottle and blow it out backwards which should clear it. Or, at least it did for me:
Turn wheels to the left.
Remove about a half dozen screws in the front of the wheel well that holds the plastic cover in place. Just the front area. There is also a plastic plug as I recall in the top, but do not pull this out.
You can peal the front of the wheel well out from underneath the fender, which will give your hand access to the washer bottle.
The pump easily pulls out of the washer bottle.
Remove the hose on the other end of the pump.
Blow it out and re-install.
Note, you will lose washer fluid when the pump is out.

This sounds like your strainer grommet (pic below) is clogged. I had the same problem not too long ago and thanks to member Jsal, I finally did it. What you have to do is get behind the mudguard in the front drivers side so turn your wheel to where you get the most clearance or you can remove the wheel which would be even better. Next thing you have to do is locate the washer fluid reservoir which you'll be able to see behind the mudguard, you'll see the hose connected to the reservoir, remove the hose (pulling up), you'll see a rubber plug on the reservoir which is the "strainer grommet" , pull it off the reservoir, let all the fluid drain out of the reservoir, clean the strainer grommet (filter), grab your garden hose, run clean water (above) to clean out the tank, put the strainer back, attach the hose back to the grommet, dont forget about the mudguard, remove excess water by running the jets, fill her up with your fav fluid, bada bing....bada boom

Was the filter visibly blocked when you took it out?

My filter was full of what looked like algae and I had to use an old toothbrush to clean it up!
All is back to normal now though...

I have posted a diy guide with photos for fixing this.

no or little water coming from the windsheild washer jets...fix
My Bentley Manual specifically points to the problem and the fix. Locate water tank as already described....disconnect the electric wire coming from the back of the pump, twist the pump clockwise while pulling pump from the tank. Remove the SCREEN from the bottom of the pump and replace (says the newer screens have larger openings to decrease this apparently problem)....I may just clean my screen if I can. All this assumes that the pump is working....you should be able to hear it pumping and some, perhaps only a bit, should be coming from the jets. This seems to be a common problem as it has a special write up in Bentley under "symptoms and field observations" in the front of the manual. Good luck, Henry
