That would be a sign of a bad clockspring under the steering wheel.

First check for spark at any of the sparkplugs.

disconnect the wires from the horn.its just a simple connector.

all you need to do is run a wire(s) from the original horn to the new horn & if you blow a fuse put a bit bigger fuse in.....hope this helps ......cheers

Do you have a multiswitch on this? Cruise not working would indicate that to me. The horn you got working, then, with the clock spring wiring.

Check to see if the cable for actuating the cruise underneath the hood at the throttle body is broken or not.

First, hook a test light to the power wire on the horn, push the horn button, and see if you have power there. If you have power, the problem is the horn itself. Maybe even run a jumper wire to the horn, and see if it will blow. Sometimes with these older trucks, it just as easy to change the whole steering column as it is to find the problem. (if you can get a column from an auto wrecker cheap) It will likely be a broken wire in the column somewhere, ususally near where it tilts.

The horn location is on the radiator support.

it could be a bad relay or just the horn is bad the horn is on or in the fender and is easly replacable horns can be purchased at any local part store and are very cheap

The cause of this is not the horn or fuse in most cases, it is caused by the rotating contact that connects the horn button, in order to repair this you will need a new clock-spring contact, to install the airbag must be disarmed, his has to be done by the book or serious injury can result.
