Which fuse is for the horn in a 1998 Ford F-150?

There's no single definitive answer to which fuse controls the horn in a 1998 Ford F-150 without looking at the owner's manual's fuse diagram. The location and fuse number vary depending on the specific trim level and options on your truck.

To find the correct fuse:

1. Consult your owner's manual: This is the most reliable source. The fuse box diagrams usually show which fuse controls which circuit.

2. Locate your fuse box(es): 1998 F-150s typically have at least one fuse box under the hood and possibly one inside the cab (often under the dash).

3. Check the fuse box diagrams: The diagrams in your owner's manual will correspond to the labeling in your fuse boxes. Look for a fuse labeled "Horn," "Horns," or something similar. Sometimes it's grouped under a larger circuit.

Without the owner's manual, trying to guess which fuse is responsible is risky and could lead to further electrical problems.
