What fuse controls cruise control and horn?

The fuse that controls both the cruise control and the horn is typically labeled as the "horn" or "cruise control" fuse in the vehicle's fuse box. The exact fuse location and designation can vary by make and model, so it's important to consult the owner's manual for your specific vehicle. If either the cruise control or horn is not functioning, checking this fuse is a good first step in troubleshooting the issue.
