Here's the fuse box diagram for your vehicle

The windshield wiper relay on a 2004 Ford F-550 is typically located in the fuse box under the hood. The fuse box is usually located near the front of the vehicle, on the driver's side. To find the windshield wiper relay, you will need to refer to your vehicle's owner's manual or a wiring diagram for the vehicle. The owner's manual should have a diagram of the fuse box that will show you the location of the windshield wiper relay. Alternatively, you can search online for a wiring diagram for your vehicle.

Once you have located the fuse box, you may need to remove a cover to access the fuses and relays. Look for a fuse or relay labeled "wiper" or "wiper relay" to find the windshield wiper relay. If you are having trouble finding the windshield wiper relay, you may want to consider consulting a mechanic or taking your vehicle to a dealership for assistance.

You should have a wiper fuse in the interior fuse box that you can pull to temporarily turn the wipers off. I suspect that the issue is due to a bad wiper switch which will need to be replaced.

Check Fuse 29, but by rights, it also covers the washer.

If that fuse is okay. try giving the wiper motor a jolt by whacking it end on with a broom handle. Can you hear the wiper motor running? Check the linkages.

Windshield Wiper System
The windshield wiper system consists of a wiper motor, a linkage, a wiper arm and a blade, and a wiper/washer switch. The windshield wiper circuit incorporates a self parking device which consists of a worm gear and a cam plate in order to keep the circuit engaged temporarily when the switch is turned off. The wiper system is driven by a permanent magnet-type motor. The windshield wiper motor is mounted on the dash panel and is directly connected to the windshield wiper linkage.
The windshield wiper motor has 2 speeds, LO and HI, and also has intermittent wiper capability. The wiper switch is an integral part of the wiper/washer switch. Windshield wiper operation is actuated through the lever on the right side of the steering column.
