Where do you start to look if your horn stops working on a 2001 gmc sierra?

Not sure if the answer is the same on an '01, but on my '04 Sierra I had the same problem. There is a big relay box under the hood on the driver's side mounted over the wheel well. There is a relay for the horn in there along with relays for many things you wouldn't think needed a relay. The layout is on the bottom of the big lid to the box. To check if it is the relay, swap it out with one of the other relays in the box. I have had to change 6 since I went over 200k. They are available at aftermarket parts stores for around $15.
