Previous owner remove the horn relay. I had no idea of why so I went to dealer and bought new one. The moment I put that relay into box the horn started. I was told that someone tamper with my alarm system. It is 96 grand cherokee laredo. Any one have idea of how to fix it.

 

It could be a bad horn switch too.

 

I believe that it is the horn switch. I took the air bag and disconnect the negative connection then plug the relay. It did not make a noise, but the moment I touch to the ground then the horn work. Do I have to replace the air bag assembly or can I just fix the switch. I look at manual, but said nothing about.

 

I'm not sure if the switch able to be replaced, or the airbag assembly needs to be replaced.
