    I've had a horn on a car go out on me.
    The one rare time I needed it, nothing.
    Since this one is still working, I wonder if you could spray something or other in it to loosen corrosion?

    Hmm, maybe rodent damage to wiring. Or insects turning a house into a home. Calls for a removal and inspection.
