The horns should have two wires connected to them. One comes from the
battery via one of the two fuses and the other wire goes to the contact that
wipes against the slide ring attached to the steering wheel. This wire gets
grounded when the ring is pushed. There should be continuity through the
horn itself. The horn should honk if you ground the wire that goes to the
steering wheel. Temporarily ground it directly at the horn. If it doesn't
make a sound and it has 12 volts on the other contact, you have a hooter
that needs some work. If it does honk, the problem is toward the steering
wheel assembly.

Lucas didn't earn the title "Prince of Darkness" for nothing. The wiring on
these cars really sucks. The biggest problem is that they use screws
intended for mechanical connection to also pass for an electrical
connection. I fought this same problem until I got irritated enough to
solder in a few extra wires and go directly to a good ground on the chassis
where it is out of the weather. The problem ceased to exist at that point.
The parking lights were a particular issue with me. You might check the
contacts on the in line connectors on the wiring harness (engine
compartment, top of fender well).
