You should try checking the pipe that leads to it from the washer reservoir, sometimes it can get kinked or even come off at one end.. Can you here the motor trying to spray the water? If not then the fuse could have blown as you should be able to hear it trying.. Good luck
First time was there was gunk in a filter from where I let it ran dry, water wasn't getting through. to double check it wasn't my washers frozen, i unhooked the pipe at one of the connections and tried it, no water = pump problem.
Garage sorted it,
Second time recently, my pump burnt out, when i tried no noise from the washer,
either way only cost £30 to repair.
Best thing is to do
1- check that the pump is making a noise, if not, burnt out
2- check the water is flowing through the pipes
3 - if not water flowing through the pipes, take to garage, maybe 20/30 for them to sort.

Originally i thought the water was frozen ( i had got screenwash with a dash of anti freeze in there) because the front and back stopped working, backs working fine again but the front hasnt been working since the weekend before last so it cant be frozen as it would of surely thawed...
I will try pulling the pipe off one end to see if the water is coming out?
It would only have thawed if the temperature around your way has got up above freezing.
The obvious explanations, especially at this time of year are:
1. Something has frozen, if the back one is onto a heated windscreen then sometimes that keeps the nozzle warmer so is less prone to freezing than the front one. If this is the case then you're a fool for not putting enough anti freeze in. There are instructions on the packet as to how much, remembering in lots of areas its getting down to -10 at night.
2. Something is gunked up. Hosing the system through can help with this, see if you can push some flow through.
3. Pumps burnt out or fuse has gone. Probably less likely if the back is working as generally driven off the same pump. Really good ways to burn your pump out or blow the fuse are to keep trying the washer when it's not working. If it doesn't work the first time, don't try again on that journey, or at least a fair while into that journey.
the hose connects thropugh the bonnet to the spray nozzle on the top of the bonnet, but in hte other dirextion the hose looks like it goes around the back of the water unit and i will have trouble getting at that, ive not laid under the bonnet to see what i can see from there as im still at work.
