    Nothing works, I've tried checking the fuses and found them OK. Has anyone any ideas please?

    no wipers OR washers is almost certainly electrical.....are you sure of the fuses...did you use a multimeter to check or just visual ?

    fuses can sometimes blow and you cant see the break.

    also, dont rely on the handbook to point you to the correct fuses....they arent always accurate and the indicated fuse may power some other accessory.

    if they all appear ok visually then use the meter.

    quickest way is to use pointed probes on the meter...not clips.

    put the neg probe to earth, turn on the ign and touch BOTH sides, in turn, of each fuse with the live probe.

    you can just touch the fuse wire link at both ends through a small hole in the plastic fuse housing. (in the case of regular blade fuses, at least)

    suspect any that dont show 12v at both sides.

    this only works with ign on.

    the other way, of course, is to pull the fuse and touch the probes to each blade with the meter set to OHMS

    if you have a coded radio ensure you have the code BEFORE pulling fuses.

    You don't say what vehicle, so difficult to comment.

    Fuse is the obvious suspect, but is wiper and washer pump on same fuse? If not, not quite so simple. (BTW, fuses don't always correspond to handbook locations - something I've found by experience)

    If it's a multifunction stalk switch, another suspect is the switch itself, or even more likely, if they aren't the same fuse, a multi-plug between switch to wiring loom is loose.
