Ford Focus water washers

On some models / years you have to remove the inner wheel arch liner (black plastic cover) to gain access.

Have you checked to see if the Nozzles are clogged. Try freeing them out with a straight pen or needle. Also you may be able to disconnect the rubber tubing from the nozzle - then press for screenwash and see what supply you are getting. Good supply = blocked nozzle. Bad supply = a problem further back the line. this will tell you if you need to get the bottle out. You can then do a similar test on the motor by disconnecting the rubber tubing from it and running it.
