What happened to my horn?

[LiKuiD]

I've had my 98' for about 3 months now and the horn has always had a nice truck-like "HONK". Now all of a sudden, when I locked my doors today it gave off a "toot." It sounds completely different now! Any ideas as to what happened? I miss my honk!!

Loose wire or a short in a wire. Mine did that and I reached down and jiggled the wires at the horn and viola, good as new.
