Easy fix, just pop off the plastic round cover at the bottom of the wiper ( covers the bolt that goes into the window ) then pull off the black plastic jet which is the thing that angles the jets to the window.

At this point try the rear washer yet to see if this is the problem as if it is you should get a jet of water shooting straight back. If it is the problem simply push a needle done the jets to unblock and refit.

Make sense ?
