Where do I find the fuse box for my car horn?
Look under the dash, on the side of the dash that’s concealed when the door is shut, or in the glove compartment inside your vehicle. Under the hood, look around the edges of the engine compartment. Some vehicles have multiple fuse boxes. If you can’t find yours, consult your owner’s manual. Remove the fuse box lid.
