Curtic, are you talking about an air horn or a statndar 12v car type horn. The air horn has a 12 v solenoid to turn the air on and off and are prone to failure. An electric horn normall has a relay. Either one the best way to troubleshoot would be with a volt meter of 12 v test lamp on the solenoid or the relay and leave the orn button alone until you find out more. have you checked the fuse?

Check for bad ground, 12 volts at and across the selenoid

I second the plan of starting at the horn end and working from there. A horn problem at the steering wheel would be pretty unusual.

You should be able to get the horn cap off of the steering wheel by turning it counterclockwise. My horn failed and I found that the horn wire going up the steering column to the horn button, switch, went bad. When you press the horn on the steering column you are supplying a chassis ground to the circuit. Testing with a meter should help you locate the problem.
