i have just replaced the washer pump the whole job took 20 mins, i just removed the rubber trim and one clip and was able to lift the scuttle panel to allow me to get a hand in and pull the pump, then it was just a case of swap the pipes over one at a time. i put some water in but still had little flow from the rear jet so i took the tailgate spoiler of pulled the jet pipe off and was able to jet full flow but did get a load of muck out as well. put it all back together and all works fine and like i said it only took 20 mins fro the job.
The reason that the pumps fail is that there is a little shuttle valve in the pump which swaps from front or rear supply and it does stick, so it is best to use both washers often to stop it from gueing up, its a case of use it or lose it

Had the same problem and the same solution !!! shuttle valve shame .....on you....

I know I'm resurrecting an old thread again :d but nevertheless I think this is useful info. I have just completely drained and refilled my washer bottle.

I have just acquired a Clio III facelift I-Music and yesterday had my first proper long 'shake-down' drive in it, on damp roads (as it happened). So of course used the washers a bit, and thought no, summink's not quite right here that looks like plain clear water. It beads and runs away too easily and doesn't actually seem to do a great deal in terms of cleaning.

So investigated today, siphoned it all out into a bucket and sure enough it certainly looked and tasted like ordinary tap water with no screenwash additive whatsoever. (You can usually smell it too when it's being sprayed.)

I had already been considering using distilled water anyway, so had already got a 'can' from Halfords.

Am I being too OTT? Distilled water? Well our tap water is very hard, so I figured that's the sort of thing ('furring up') that could cause problems for moving parts in the car's washer system. If it's got a rotating motor or valves, then even more so!

Made up a batch of screenwash & distilled mix, and refilled. For some time I have always added a generous dose of screenwash anyway even for the Summertime, by 'generous' I mean at least the recommended ratio for Winter; apart from the screenwash having antifreeze properties, it also contains solvents and detergent for actually cleaning stuff off, plus, the soapiness is a good lubricant for the wiper blades too.

Top tip I think

I have the same problem got my Clio last June and when you twist to activate the rear washer my front ones go but nothing from rear. The wiper still works on the rear when you twist it but front wipers don't go so I then have to flick on the intermittent to clear it! Hope that makes sense. Anyone have any ideas? Thanks
