General Description

The horn system starts at the fuse block with the horn/dome fuse. The circuit goes from the fuse block to the horn relay in the underhood convenience center. At the horn relay, the circuit splits; one branch goes through the relay coil to the horn switch in the steering column, and the other goes through the relay contacts to the horn.

When the horn switch is closed, it provides a ground path for the horn relay coil. Current flows into the relay coil, closing the contacts, allowing the horn to sound.
