Intermittent horn problem 1995 LHS

I have a 1995 LHS. Sometimes the horn will work, but usually doesn't. Any ideas on what is causing this? Thanks.

sonds like a bad wire connection,or wire is broken inside causing an open circuit.......or maybe the contacts in the buttons on the steering wheel.
if you have a voltage meter,check connector at the horn for battery voltage,have someone push the horn while you check the wire,try wiggling the wires while someone holds the horn on also........car does not need to be running.horn is located on the lower right side of the engine compartment

Thanks for getting back. Checked the connections and it is still doing the same thing. The horn, when it works, is good until I turn the engine off. When I restart it, no horn. It may not work for a week or two and then the same thing happens.
