My windscreen wiper intermittent setting not working?

The intermittent setting on my windscreen wipers won't work at all but all other settings work, even the back 1. Which relay could be faulty as I want to check that before paying out for any parts?

Also the front windscreen washer won't work, the pump isnt working at all. I have changed the fuse but still the same, there's plenty of fluid in the car and from what I can see no leaks anywhere.

Would really appreciate some advice on both problems.

Thanks
