Recently with my 1993 Grand Wagoneer I had an issue where my horn would randomly sound by itself as I was turning the steering wheel one way or the other. For reference the ordeal is described in my previous thread http://www.jeepforum.com/forum/f13/h...l#post15398973
The steering wheel would emit slight grinding noises when turned also. I ended up removing the clockspring, of which the wires were all screwed up inside. Not needing either the cruise control or the airbag, and deciding not to replace the clockspring, I left the clockspring wiring connector just unplugged and hanging, and the horn wire from the horn buttons in the steering wheel disconnected, with a plan to simply run a wire from the horn wire terminal in the steering wheel through the hole in the back of the steering wheel and connecting it to the Gray/Orange horn wire at the clockspring wire connector so that I could continue to have an operational horn when pressing the horn buttons on the steering wheel. I did a temporary connection as just described, which did indeed sound the horn when I pressed the steering wheel horn buttons. Then I disconnected my temporary connection until I could get a better terminal tab attached on the end of my wire. So, meanwhile, with no connection at all to the horn wire in the steering wheel, all of a sudden after sitting overnight the horn started honking by itself. It honked several times intermittently and then stayed on honking solid, until I could run out and disconnect the battery to stop it.
I know this confounded vehicle is full of the factory installed vehicle theft security system, which, depending upon a variety of factors etc will cause the horn to sound. Also, according to the service manual there is an airbag sensor plug connection tied in with the horn wire harness at the horns themselves. As I mentioned, I do have the airbag unplugged at the steering wheel, but haven't a clue whether that has anything to do with why the horn went off as just described. Also, I haven't a clue whether the horn went off because of some function (or malfunction) of the anti-theft system.
Apparently, even with the horn wire at the steering wheel disconnected, the horn relay is getting grounded somehow, providing battery voltage to the horns. But I don't know how.
What I'm hoping for is an easy fix, like perhaps just needing to replace the horn relay. Does it sound possible that a bad horn relay could be the cause of the horn sounding as I described, suddenly, all by itself?
Any comments/advice appreciated.
Also, is there a method to disable and permanently disarm anything and everything to do with the vehicle security system. I dont need it, dont like it, and dont want it, any of it. thanks
