Question about 1998-2002 Park Avenue Door Lock & Alarm Interface
Can't find horn wiring diagram for 1994 Buick Park Ave Ultra, horn switch is not getting power at all.
Have you checked the fuses? ON a buick, under the steering column there will be a set of wires. When depressing on the horm there will be 12 volt ground to the black wire. The black wire is the wire that goes to the horn relay. If you can trace ground through the wire to the relay, then the problem could be your relay. You can also put +12 volt to the horn to be sure the horn is good. If the horn sounds when putting a +12 volts the the problem again could be the relay.
