Haven't used the horn in my 2000 blazer for months. Then, someone cut me off and, when I tried the horn . . . nothing. (I couldn't even honk when she flipped me off). I checked the fuse and relay. The fuse seems ok. Does anyone have any ideas on what to try? Where is the horn physically located in the engine bay? Thanks in advance.

It might be a disconnected wire on the steering column. Usually there is a piece that comes off to access the horn wiring, but you might have to take the whole air bag assembly off the steering wheel if you have air bags, and check the wires to see if one was disconnected. Otherwise I'm not sure where my horn is in the engine compartment, so check the steering wheel first and see if that's the problem.

Same issue with my 2000. It was the horn contacts ($19 from my Chevy dealer). There are two behind the air bag.

I had the same problem with my 2000 blazer. I came across the following fix from another website. Hold down the horn button and turn the steering wheel back and forth until the horn starts to work. The contacts get dirty and this corrects the problem. Couldn't believe it worked! Hope it works for you too!
