As attached below is the circuit diagram, you are correct the wipers are on the same fuse supply as the washers (F13)

If you have access to a multimeter pull the plug at the motor, set the meter to DC volts (12 volts or more) carefully push the probes into the the connectors at the plug (you may have to put some small pins in the plug as the probes may not fit) and get someone to switch on the ignition and operate the switch, if it shows 12 volts then the issue is the motor, or the same if you have a 12v test light. If you have no voltage you will have to investigate the switch or wiring (unlikely) You can also check the motor with the multimeter, set it to ohms, remove the plug and put the probes on the motor terminals, you should get around 7 - 8 ohms; if its mega ohms the the motor is open circuit (probable)
