How do you fix a Jeep Wrangler horn?

To fix a Jeep Wrangler horn, first check the fuse related to the horn in the fuse box; replace it if it’s blown. Next, inspect the horn relay and wiring for any damage or loose connections. If the horn still isn’t working, test the horn itself by connecting it directly to a power source. If it doesn’t sound, you may need to replace the horn.
