I have a '05 Z71 Suburban and the horn quit working. I have checked the fuse and replaced the relay. The horn does work when I either jump the fuse or use the key fob panic button to activate it.I don't get a click at the relay when someone pushes the horn. I suspect the contact in the steering wheel. I have never taken the steering wheel apart. Can someone give me some ideas of what it might be and things to check or instruct me how to get to the contacts buy disabling the Airbag and removing it.

Thank you,
