Screen wash not working properly
I've read back over the many threads on here about the screen wash filter getting clogged with organic gunk, and I'm wondering whether that is what is happening here (it's happened before but symptoms weren't exactly the same).
I'm getting nothing out of the jets when I pull the wiper stalk. In the past I've effected a temporary fix by using something like a bicycle pump to blow back down the pipe into the reservoir, so I've tried that again and it allows me to get 3 or 4 squirts out of the washers, of decreasing intensity, then nothing. In the past when I've done this, I've normally got a few months grace as a result, so I'm a bit puzzled that it is not working for me this time. There was clearly a problem with the screenwash for my MOT, which caused the garage to replace the pump (probably unnecessarily). But judging from the smell when I've used the bicycle pump trick, they didn't empty and clean the reservoir or filter. I think I may have to face the dauntingly smelly task of doing this myself, if I can work out how to do it. I understand I need to remove the front wheel lining on the driver's side to access it, but it's not immediately apparent to me how to do this. Do I need to remove the wheel to do so, or can I do it just by turning the wheel as far I can in one direction (in which case, which direction)? If this at all a tricky job, I'll hand it off to a garage but if it's simple enough that even a mechanical idiot can do it, I'll give it a go. |

Hello John,
I'd recommend taking off the wheel for access and visibility. The wheel arch liner is secured mainly with plastic devices called a Scrivet. Unscrew the Posidriv head gently then carefully lever out the shoulder which has two tentacles on it. There are some other fixings too; a Haynes manual is useful to find these. I'd definitely have a go yourself John. Simon

Take the moulded trim off, the one that is screwed beneath the bottle and using a torch have a good look to see if there is obviously any crud in there. You may be able to get the pump off, then use a bottle of clean water "plumb" them together to test the system. |

Is the pump running when you operate the switch? If so turn wheels into full left lock move wheel arch liner aside undo screw half way up you will see pump on side of bottle lift vertically till bottom of pump out of filter then pull from clip leave wire and pipe attached, pickle black filter from bottle wash out flush tank and refit, Should take you about 15 minutes

Hi John.
If you are up for the job and you want to cleanout the washer bottle properly, then remove the front bumper which takes about 20 minutes, you will then have complete access to the washer bottle. You can then go from there, but do not dis miss the valve under the bonnet covering these can fail or work intermittently this happened to my MGZT the fix remove the valve and replace with a T joint never had ant trouble after that. Could be the little filter in the bottle. 1 2 Remove and clean under the warm tap. 3 As i say above could be valve. 4 5 Replace with one of these Tor a Y will do. 6 You have tried the bike pump test. 7 8

can the washer jets be removed from the pipe at the bonnet and then a check be done to see if screen wash flows freely and with some force out of the pipes?
The jets may be blocked macafee2 |

Arctic, I'm assuming that the problem is at the pump or reservoir, rather than the valve near the jets, or the jets themselves. I detached the pipe where it meets the T and put it in a bucket and tested it, and nothing came out into the bucket, until I had put a blast of air down the pipe with the bicycle pump.
Also, the jets themselves don't appear to be blocked - I was able to blow a little air through them with the same bicycle pump technique. |

Did the same with the 1.8T and the 260. When I went to get the ones for the 260 I think Ford had got wise to people fitting the jets to other cars, IIRC they were about double the price.
