Unusual Horn Problem and Fix - The 1947 - Present Chevrolet & GMC Truck Message Board Network

2004 Silverado. Horn started failing intermittently. Then died all together. Inspection time was coming up so had to try to find out why. Only thing I could think of was to check the fuses. I certainly didn't want to go into the center steering wheel cushion with the air bag! Pulled various fuses and they were all good. Then, tried the horn again and it worked! I suppose the fuse was either not seated properly or it had built up some resistance or corrosion. Anyway, horn honked and I get her reinspected for another year. Might be helpful if your horn quits working.

I'm thinking coincidence. probably the clock spring inside steering column. If wheel is turned just right (or wrong) it will work (or not)

The part that is not a coincidence is that it was sitting in the drive, horn not working, and I pulled fuses and tested the horn after each one, and voila, it started working! No moving of the steering wheel involved. Ignition wasn't even on. What is probably the case is that some time ago, I was checking for something else I thought might have been a blown fuse. Could'a pulled the horn fuse and not quite gotten completely reseated. Since I don't use the horn much, might'a gone unnoticed till recently.
