SOURCE: horn wont blow

the problem is the rotating contact that connects the horn to the steering column wiring harness, this part is called the clock-spring contact, u must remove the steering wheel to change the part out.

check for broken wires the neagative is by the horn button in the steering wheel has air bag ever been replaced in steering wheel if so the wire may have not been plugged in

SOURCE: 1999 toyota corolla Horn doesn't work.

Usually the wire from the steering wheel is Green w/Red and the wire to the horn from the fuse box is White. There is only one fuse, sometimes shared with the emergency lights. Check to see if there is power to the horn itself with a volt meter.

If the horn works with direct connection, and fuse, relay, and circuit breaker are all good, it's the switch in the steering wheel. If it is anything like the chrysler auto's, the switch and the air bag module is all one unit, can't replace just the switch, the whole thing, and it's about $700 to $800 for those units, at least it is here, and can only get them at a dealer.

You have to first check for power to the horns. Remove the plastic panel under the hood on top of the radiator support. The horns will be there on the side of the radiator support. Hook a 12V test light or volt meter to them and press the horn button and see if you have power there. If you do its a bad horn if you don't then check fuse no. 5 (15amp) in the engine compartment fuse panel. If it is good then the next step is to eliminate the relay also located in the engine compartment fuse box. Basically how it works is the no. 5 fuse feeds both sides of the relay. You have a switch side on the relay that feeds the horns and a coil side which when energized by the horn button creates a magnetic field which closes the switch in the relay and blows the horn.
If you have no power to the horn and your fuse is good try swapping the relay with another one in the fuse panel if it still doesn't work then go to the connector located at the blower motor under the hood,there will be 2 connectors that run on top of the blower motor,the one you want is the bottom one of the 2. It will be a square 12 pin connector. Find the dark blue wire there and ground it if horn blows then it will be the clock-spring or the horn button itself.
