To find the correct fuse:
1. Consult your owner's manual: This is the best resource. It will have a fuse diagram showing the location of all fuses and what each one controls.
2. Check the fuse box diagrams: There are usually multiple fuse boxes in a Ford F-150. One is typically under the hood, and another is often located inside the cab (usually under the dash). Look for diagrams on the inside of the lid of each fuse box. These diagrams will show you which fuse controls what.
3. Look for a fuse labeled "Horn" or a similar designation: The fuse might be labeled directly, or it might be listed in the diagram.
Without your owner's manual or access to the fuse box diagrams, I cannot provide the specific fuse number.
