My horn NEVER works when I beep at someone on the road, nor when I lock the car and put the alram on (it would beep once to let me know this was done before.) However every once in a when I lock the doors and turn the alarm on it DOES beep (maybe once a month this happens.) What gives? Is there a loose wire, a dying fuse, or the horn just slowly going on me? I have never had this issue with a car before. Thanks!

Have someone listen under the hood for the sound of a clicking relay as someone actuates the horn ring. Remember if the horn does blow you might scare the listener!!!
If no click check for the under hood relay. If relay not activating check the horn ring. Some times adjacent relays have same pin out/part number. Swap relay and try. Many of the cars use a "clock spring" design on the wheel. Problem air bag circuit makes it difficult to service. Check to make sure all other services are working attached to the wheel (Speed control, radio,etc). If clock spring is failing eventually other circuits would be affected.
If you have key-less entry and have a horn beep confirmation try the FOB. No beep than maybe horn clock spring OK! In no horn beep confirmation try the panic on the FOB. That should make a little noise, and if nothing else you can check your lights.
Ck the fuse if OK
Hot wire horn if still no horn
Check to see if there is 12 volts at the horn positive connection when someone pushes the horn button on the steering wheel. If there is voltage, and no sound, you need a new horn. If there is no voltage when the horn button is pressed, you need to troubleshoot the rest of the electrical circuit. First look in your fuse box for a blown horn fuse. Then try replacing the horn relay.
BLOWN FUSE.. DID WINDOWS STOP WORKING ALSO? OR WIPERS FOR THE HORN HAS SEVERAL ITEMS ON THAT SAME FUSE... OR THE WIRE CAME OFF THE HORN.. BEEN DOWN BUMPY ROAD/ ROUGH DIRT ROADS/ WASH BOARD ROADS/? IF SO THEN THE WIRE CAME OFF THE HORN..
holdboth the lock and unlosk buttons on your remote simultaneously for about five seconds until the lights flash and horn chirps.that should do it.if not i believe these models used a separate horn for security system.possibly fuse for this horn is bad or the horn itself is bad.to see if this horn works lower drivers window.stand outside vehicle and lock doors with remote.wait about a minute and reach in window and MANUALLY unlock and open door(do not use power door lock button)this should cause the system to activate...horn should beep and headlamps should flash.if horn beeps try my first suggestion.if it doesnt beep and just the head lamps flash check fuses and horn for security system.
The security module sends a signal to the horn when applying the lock button. The module is starting to go bad on you. I would replace it before you get stranded on the road for if totally bad the car will not start
