More than likely it is the horn pad switch on the steering wheel. Since you will be working around the air bag disable it by removing the negative terminal of the battery for 5 minutes and then leave it disconnected.

To remove the air bag take the 2 scews out from the back. Disconnect the connectors for the air bag and horn.

Check for continuity on the horn button by placing the Volt-Ohmeter leads to the connector for the horn
on the component side of the circuit. With the horn pressed it should show continuity on the Ohm-meter. If it doesn't replace the horn switch pad. Take the 2 phillips head screws out on the side to remove horn switch pad.
