Well first you have to find out what is wrong with the horn and than fix the problem, could be loose wires, horn could be bad, the wires could have rusted. your best bet is to cut the wires, unbolt the horn and hook up a brand new one and then put some wire nuts on there and if that dont work than your wiring is bad.
