My rear washer doesn't work. I've located the problem to be that there is just a loose hose under the bonnet. It squirts screen wash so guess it just needs connecting up. However I can't find where to connect it. Any ideas?

I did what It does on my cinquecento on this drawing, where the circle is there is a connection.
Green front
Red rear
You may find that if it hasn't been used it a while it can take a while to pump through, or that it is blocked (after connecting it)

Loop the loop not essential

Thank you! Found it was just a connection broken.
Easy fix. Hose was hiding behind some cables. Thanks for the diagram and link. Helped me to locate it!
