My horn is not working but the alarm go' s off and it works....

You need a test light .connect the clamp end to the battery positive post . then remove the horn relay .prob pin 86. have some hold the horn button down .it should light if the circuit is ok. if not then remove the 4 or 2 bolts that hold the air bag to the steering wheel .do not unplug or appliy power to the yellow connector it will deploy the air bag. you should see the two black wires to the horn buttons. with a ohm.meter mesure the one that gose to the clock spring assembley.it should be open untill you press the horn button then it should short to ground. if it dose the clock spring is bad. but you will want to test it first.

• Check the fuse under the dash. The security system either has it's own horn or is hard wired into your horn. If it was not someone could pull the fuse to disable the horn blowing while steeling your vehicle. Check your horn fuse under the dash.
