Horn works when set to alarm but does not work from the steering wheel?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

Many car users notice this problem.That horn works when car alarm is set,but will not work when horn key pad is pressed on steering wheel.

Its not a horn issue.

The horn has power all of the time but does not go off untill it is grounded. The switch in the steering wheel is the ground when you press it completing the circuit and sounding the horn. The alarm does not use the steering column or steering wheel ground path to "beep" the horn, it uses its own ground. The problem then will more than likely be in the steering column, steering wheel switches, or clock-spring. The clock spring is not for the clock. It is a spiral-wound wire set that allows the steering wheel to turn and not bind up the wires going into the steering wheel. It is called a clock-spring due to the "spiral" wound design of the connector. The horn ground wire in the steering wheel gets its connection through this clock-spring, so it may the source of your problem. It would require some electrical diagnostics to verify the actual point of failure.
This details will help.
