HI, Try to find out first what is the part that cause the malfunction of the horn. The three major part of the horn is the relay, harness & horn pad, and horn itself. Check the relay if it is functioning by replacing it with similar type ( if you have the spare or a similar relay in the relay/fuse box in engine compartment ). Let somebody push the pad horn and if you hear a clicking sound on the relay, it means there is a current that activates the relay( no probs from the horn pad and harness ). Check the horn, just get a wire and directly connect it to the positive pole of the battery and connect it( wire ) to the positive terminal of the horn, it should activate the horn, if not the problem is the horn and you have to replace it.
Check first the FUSE!
Check the relay!
Then let somebody push the horn pad in the steering wheel, while u listen at the RELAY, if you hear any "click" sound that means relay is working!
If the relay is working NOW the problem lies in the HORN itself and needs to be replace!
Check the wiring too! There might a disconnected wire or a FAULTY ground to the HORN!
Taah!
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.
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.
