The wiper and washer motors us the same fuse. So if the wipers work, it's not the fuse. The washer motor wiring, the top wire is voltage, bottom wire is ground. As you can see, at the wiper/washer switch, #5 sends voltage for washer motor, you can see the wire colors. If good voltage and ground and no washer action suspect the washer motor. Before replacing anything, make sure the plumbing from washer fluid to windshield is not clogged.
