I have a 1991 Geo Tracker 4x4 with the exact same problem. I'm a hardcore 4x4 Tracker/Sidekick enthusiast and also a seasoned mechanic, and have never heard of this quirk on any other Tracker model year. I possess both the Factory GEO Service Manuals and an aftermarket Haynes manual which contain fully detailed electrical schematics. (NOTE: The Haynes manual sucks, cause it's a combo Samurai/Sidekick/Tracker manual that seems to mostly cover the Samurai, even though that model is a totally different breed) I am in the process of tracking down the glitch, and will post my findings as soon as I discover and perform the repair.

the ignition switch tumbler on these models seem to grenade from the inside you would have to replace the tumbler
The system will be disarmed only when the unlock button on the remote transmitter is pushed or the ignition key is turned "ON".
Cuz if they had two it would look weird
the only animal born with horn is giraffe.
The radio time would stay on if you had the keys in the ignition but the ignition was only turned halfway.
I have two answers, one with a question. 1. Why use this feature anyway? You press the lock button twice to get the horn, right? What's the point. Just press it once, you see the lights blink, you know it's locked. No need to tell the neighbors everytime you lock you car doors with the horn. 2. If you must use the horn function, how about adding a logic circuit between the horn and the ignition? This way, the horn will only work when the ignition is on. You will need a power AND logic circut.
Sounds like the steering column shaft isn't grounded. When you push the horn pad, you are completing an electrical circuit which closes a relay & sends power to the horn & the horn sounds. If the steering shaft has no ground then the horn won't sound. The shaft has to have ground from the top where the horn slip ring is to body ground. Now for the horn working with the engine off. The only reason I can see for the horn working with the engine off is that the ignition key would be in the off position therefore the lock pin which is in behind the steering wheel locks the steering wheel is providing an alternate ground path which completes the circuit for horn operation. This ofcourse is not the correct circuit. Cheapest repair is a universal horn button installed. Button $5-$10.00 & install approx. $30.00.
A horn of plenty can only be used once.
Loose or corroded battery cables? Weak battery? Bad ignition switch?
Yes, the 1989 - 1998 Trackers are the same ANSWER: The above answer is only partially right. Yes the '94 console will fit in an '92 Tracker. Only '89 through '95 Trackers are the same. '96 through '98 are the different then previous years.
Poor ground, or defective horn.
That would be an alarm the horn is behind the grill
