Check fuse. The horn is on the same fuse as the cig lighter...check your cig lighter to see if it works. if it's working it could be a short on the wire to the horn..or the horn just might need to be replaced.

Where is the horn relay located on a 1983 Z-28?

I have a 1982 Z28. I am in the middle of replacing all of the relays and fuses in it. There is a plethora of relays behind the dash, removal is necessary and is a relatively arduous task. I recommend you replace all of the relays if you have not done so yet. They are all as old as me and have probably been used as often to boot. There are also relays behind the radio enclosure and in the center console. I believe the horn relay is on the drivers side near the computer dock. Good luck.

Where is the horn fuse for caprice 1992 and what size should be used?

It's a 15 amp fuse. It is in the no 1 position on the fuse box. The fuse box is located on the drivers side; you can see it when you open the door its flush against the panel that has the steering wheel.

Why would the horn fuse keep blowing?

A suggestion: First things first. Check owner's manual to see if there are other devices sharing the same fuse. If there is only the horn on that circuit, pull wire off the horn. Push horn button to see if the fuse still blows. If it doesn't then you know the horn element is shorted and the horn must be replaced. In my car, the horn shares a circuit with the cigarette lighter and interior lights. The cigarette lighter is a common cause of a short and thus will also short out the other devices. So, if it is a shared circuit, by process of elimination(disconnecting each device one-by-on) the short should be located and that device replaced.

Horn won't blow on 1984 Chevy?

Good "Troubleshooting" is the Key

No one can tell you how to fix something without knowing what is causing the problem.

Horn "failure" could be caused by one or more of several things.

In order to fix the problem, someone who knows what he/she is doing needs to troubleshoot the entire horn wiring system including:

  • First the fuse for the horn circuit.
  • All connectors, plugs, splices, etc. [for being disconnected, loose, or corroded]
  • All wires in the horn circuit for cuts, breaks, orunintended grounding.
  • The horn relay [if so equipped].
  • The horn ground [for looseness and/or corrosion is key issue here]. Usually horns are grounded internally [no external ground wire] and thus are grounded by their mounting mounting bracket to the sheet metal of the vehicle. IF corrosion builds up between the mounting bracket and the sheet metal it's mounted on, then that acts like turning off a switch.
  • Most horns operate using a vibrating internal set of points, and sometimes are adjustable. Over time, wear can cause the point "gap" to change and prevent the horn from working. The adjustment is a small "screw" on the back of the horn that doesn't have a "head," but only a small slot in the screw shaft. The screw has a nut which is used to "lock" the setscrew once it is properly adjusted. To adjust, insert a screwdriver in the slot and hold the screw while using a small open end wrench to loosen the lock-nut. Then have a "helper" hold the horn "button" down. While the horn button switch is being held down [switch closed], you gently turn the adjusting screw back and forth a little at a time until the horn starts to blow. Then continue to "tweak" the adjustment until the best horn "sound" is achieved. IF this process does not allow the horn to blow, then it's probable that the horn button/switch is defective.
  • The last item to check is the horn switch button itself because it's inside the steering wheel cover and thus is the most difficult component to get to.

There are probably other things which don't come to my mind now. Good luck!
