Bobby 6/28/2010should be a relay check the relay center under the hood, could possibly just be on a fuse so check the fuse under the dash also
jim 6/28/2010Nope there isn't a relay to be found.
Bobby 6/28/2010The horn may not be on a relay could be just direct wired. I don' t have a wiring diagram for it but if the horn is not working first thing i would do is check for power to the horn when it is being pressed. if no power check the fuse. If no power there it could be the horn button. if there is power to the horn check the grounds and probably replace the horn
