Install an auxilliary horn button on dash board
if the horn is already there and is bad, just disconnect the two wires on it, unscrew horn, remove it and reinstall the new one and reconnect the wires. If you don't have a horn, then find a suitable place under the hood and drill X number of holes. The switch is wired in series with the battery and horn. The button is placed at a convenient place you can get to it when you want to blow the horn.
To replace the horn button in a Mitsubishi Lancer, you first need to disconnect the car's battery to prevent any electrical mishaps. Next, you'll need to carefully remove the old horn button by prying it off with a flathead screwdriver. Once removed, you can then install the new horn button by aligning it correctly and pressing it into place until it snaps securely. Finally, reconnect the car's battery and test the horn to ensure it is functioning properly.

Sounds like the steering column shaft isn't grounded. When you push the horn pad, you are completing an electrical circuit which closes a relay & sends power to the horn & the horn sounds. If the steering shaft has no ground then the horn won't sound. The shaft has to have ground from the top where the horn slip ring is to body ground. Now for the horn working with the engine off. The only reason I can see for the horn working with the engine off is that the ignition key would be in the off position therefore the lock pin which is in behind the steering wheel locks the steering wheel is providing an alternate ground path which completes the circuit for horn operation. This ofcourse is not the correct circuit. Cheapest repair is a universal horn button installed. Button $5-$10.00 & install approx. $30.00.
Push the car horn button....
If it is the same as my 68, the horn button is held in place by a rubber o-ring under the button. carrefully work a thin, flat screw driver under the edge of the horn button and TWIST. Be careful not to chip the button. This should pop out the horn button.

Broken Or Disconnected Wire To The Horn. Check For Voltage When Horn Button Is Pushed At The Wire After Removing It From The Horn. On A Vet Probably Not Grounded.
