mended mine today by removing the offside front wheel to gain access to the wheel arch liner. remove 1 screw that holds the liner to the bumper and you can pull the plastic back to get to the bottom of the washer bottle where there are 2 pumps for the front and rear wipers the nearest pump is the rear one, take off the pipe the water from the bottle will leak out turn on the rear wash to see if the pump is working it shoots out quite fast if it is. if the pump is fine I conected an air line and using air duster blew through the pipe and cleared the blockage.
