My horn is not working?

Really you need to tell us what car you are talking about. First thing is to see whether the horn fuse has blown. One thing you can do is to look under and around the front valence area. The trouble with locating horns in this area are that any connectors on the horn become corroded. One way of checking the horn is to obtain a piece of insulated wire and connect one end to the where the wiring connects to the horn and the other end touch the positive terminal of the battery. This should sound the horn. If it doesn't then you need to clean up the terminals, particularly the earth or remove the horn itself and clean it if it is attached to metal as it will earth itself through the chassis. If this still doesn't solve the problem then you need to start by looking at the steering wheel switch. This will need to be done by a professional due to the airbag.
