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.
It's in the main fuse box under the hood! When you remove the top, look at the lower side(underneath) of it to see a diagram which tell you the name and location of the fuses/relays.

There are two relay's located in the under hood fuse / relay box . Windshield wiper on / off relay an windshield wiper speed relay .Both relay's are controlled by the FEM - front electronic module . The prudent thing to do would be to take to a qualified repair shop that has a professional type scan tool to check for DTC'S - diagnostic trouble codes rather then play a guessing game . Changing parts that don't fix the problem . The wiper switch is a input to the ( FEM ) when an input is seen the (FEM) then energizes the relay's .
Here is a link to your owner's manual from Ford.
