Your 1980 corvette horn does not work is there a relay?

No, the 1980 Corvette does not use a relay for the horn circuit. The horn is directly controlled by the steering wheel horn contact and the horn itself. The problem is likely one of the following:

* Horn itself: The horn could be faulty. Test it directly with a battery (carefully!) to see if it works.

* Wiring: There could be a break or short in the wiring between the steering wheel and the horn. Check the wires for damage or corrosion, particularly near the steering column.

* Steering wheel horn contact: The contact in the steering wheel may be worn or broken. This is a common failure point.

* Fuse: While less common for just the horn, check the fuse (if your model has one dedicated to the horn). Your owner's manual will show the fuse box diagram.

Since there's no relay, troubleshooting involves directly checking the horn, wiring, and the horn contact in the steering wheel. A multimeter would be helpful to check for continuity in the circuit.
