The fuse for the windscreen washers on a Citoen Xsara Picasso is located in the engine. It is inside the compartment box.
I think it is No.9 as this is the one for the wipers also
under the bonnet left hand side by the reservoir for the windscreen washers just press it in if it don't click it ain't the problem
the fuses are in the boot on the left side
when looking at the fuse box in the engine compartment the fuse is the last but one on your right in the row nearest you . It is a red 10 amp mini fuse. It can be tricky to get at!!
Most likely, it isn't a fuse. Windshield/windscreen washers and wipers typically use a relay, rather than a fuse.
No idea but I have the same problem with mine !

Under the hood in the container that says something like Windshield Washer Fluid.

Towards the windscreen end of the fusebox under a plastic cover within the fuse box
The fusebox for front windscreen for my 1985 Nissan 300zx is just under the hood, near the battery. I hope this helps if Nissan didn't change things. It is a small black box with fuse sceme on top. Some of these boxes are located near a head light. The other fuse box is located by the footrest for you left foot.
They should be with the others under the dashboard right hand side by the drivers door.
