Cheers guys, I got my front wipers sorted by stripping down the wiper motor to find it had water in. Dried out brushes, windings etc lubed with WD 40, now working a treat.

However, my rear wiper is not getting water to the jet, due to a one way valve in the engine compartment not working properly, i think.( water jets out of hole on top of valve.

Any suggestions.??

Cheers.

Had the same prob on cinq i followed the pipe from

bottle and found a small plastic insert in the line

opened it up with a penknife blade and found the rubber

valve had broke so took out the insides and replaced its worked ok since.

I had exactly the same on mine.
Basically it stopped the jets working. I replaced the one way valve with a standard 'T' piece and they work fine now.
