How do you fix a broken horn that does not turn off on a 2001 Mitsubishi mirage?

To fix a broken horn that won't turn off on a 2001 Mitsubishi Mirage, first check the horn relay and fuse in the fuse box for any issues. If they are functioning, inspect the horn switch in the steering wheel for any stuck components. Alternatively, you can disconnect the horn wire temporarily as a quick fix until you can replace the faulty switch or relay. If you're not comfortable diagnosing the issue, consider consulting a mechanic for a thorough inspection.
