Question Horn not working 2003 Toyota Matrix

I'm trying to research how to DIY horn repair on a 2003 Toyota Matrix. I checked the fuse and it looks OK. I replaced it just in case and still not working. Not sure where to go from here to troubleshoot and repair. Wouldn't you guess, not working and needs inspection sticker. Any help or suggestions would be greatly appreciated. Thanks!!

Horns are usually simple systems: fuse, button, relay, horn and all the associated connections. The next easiest thing to check is the relay. You should find it in the underhood fuse/relay panel. Switch it with another relay in the box (it must be the same kind) and try the horn.

If it still doesn't work, find the horn and using a test light see if it is getting power when someone pushes the horn button. If it is getting power make sure the horn is grounded either by the mount or a separate wire.

If all of that is good and you still get no sound the problem could be the button, wiring or connections. If you need more help checking these post back.
