Cut back the positive wire enough to check the voltage on good wire , not just at the plug. if you still have bad voltage check the ground to see if you are getting decent continuity! if all is still no good replace the wire from the fuse block to the horn. this is not as scary as it sounds and then you'll be back on the road good luck

I have a 1992 /98 0lds the air condition will not work unless I take the ground wire lose then it kicks in but it show that makes car is over heating when it is not what sencer is doing this please help firstname.lastname@example.org it is hot in texas
have you checked the fuse for the horn you don`t say what you have done to this point,if the fuse is good and you hear a click when you push on the horn button, then the horn relay is good as that is what is clicking,if not you will have to check the horn itself as some relays won`t work if the horn not itself is not working,by running a jumper wire from the battery positive to the terminal on the horn, it should work if not then the horn is the problem.the relay is on the fuse panel under the dash.I think it is a square sided relay
You have to test the wiring between the relay and the horn. First make sure that you have 12 volts at the relay terminal that feeds the horn, then make sure that the wire on the horn is getting the 12 volts when you push the button. Finally make sure the ground is good where the horn is mounted. If the ground is bad, run a ground wire from the engine block or battery to the point where the horn is mounted.
