spontaneous horn failure in 01 silverado 6.6
recently our horn just quit working with no explanation.
my car's horn went once and it was gradual, this was just horn one day then nothing the next.
if you press the horn and listen near the horns you can hear the snap like it's turning on, but no horn.
before I repalce the horn itself is there something else that might fail?
checked the fuses and they are good.
coudl it be wiring etc?
thanks
