2002 Mercury Mountaineer

I purchase this truck and the car horn does not work. When looked under the hood I found that the previous owner had installed air horns and they do not work. Now I have two horns under my hood that do not work. The air horns seem to be connected. I just need on or the other to work. I feel like it is not in the inside of my truck because when I press the plate to blow them I can hear a clicking noise in the speakers. Please help

An air horn would require an air compressor that is not original equipment for your vehicle. The previous owner may have removed the air compressor for the horn but never rewired the original horn. The best bet would be to rewire the original horn to the switch.
