The horn on my car was unhooked before i got it and i dont know how to hook it back up

If the security system is armed, which it can be whenever the battery power is unhooked then hooked up again as the system thinks a theft attempt has been made, try this: Hook up the battery then lock and unlock the driver door using the original key. This will let the system know that you - the owner - have the key and are not trying to steal it. Not a guaranteed fix but works about 90% of the time.

if all else fails get an air horn and blow it at the same time the horn gets pressed to make the inspector think it works. ;)
Try popping the hood on your car and look for the horn. They should be up near the front by the radiator or headlights then take the connections off and replace them securely. If no luck there replace the fuse, the fuses dont always look blown when they stop functioning. After that take the horns out of your car (usually just a screw to dismount the bracket holding the two horns to the panel.) and manually hook power up to them by touching wires to the ports and then power on the wire. (i know that we allways make sure there isnt power to the wire before we need there to be there because its just not safe...right?) At this point you should know your problem. If not than you need to test your power leading into your horn.

BRAD: LOOK UNDER HOOD SEE IF YOU CAN FIND THE HORNS THEY SOULD BE IN RIGHT-LEFT FENDERS PULL THE WIRES OFF THERE SOULD BE A PLUS + SIGN AND - GROUND SIGN TAKE A WIRE BEAR BOTH ENDS HOOK ONE END TO HORN-N-OTHER END TO SOMETHING METAL UNDER HOOD ON THE GROUND SIDE ON THE OTHER SIDE THE +PLUS SIDE GET ON WIRE LONG ENUFF TO GO FROM HORN TO INSIDE CAB BEAR BOTH ENDS HOOK TO HORN BUTTON ON OTHER SIDE OF BUTTON PUT OTHER WIRE BEARED AT BOTH ENDS HOOK ONE END OF WIRE TO BUTTON-N-OTHER END TO A FUSE IN FUSE BOX IT SOULD BE ON DRIVERS SIDE OF DAS HOPE THIS HELPED YOU SIGNED PHIL

try unhooking batt.for 15 mins,after unhooking batt,push horn button to get rid of all electric in car,than hook batt, back up,than turn key to on poss,for 30 seconds,dont start,that will let computer read the codes, than try locks

turn the key on disconnect the negative battery cable then disconnect the positive then hold down the breaks or hit the horn until it stops blowing or you cant see the break lights any more then wait 15 minutes for computers memory to clear then turn the key off and hook your battery back up and start vehicle computer should be reset. make sure to hit either brakes or horn cars store a small amount of electricity even after the battery is unhooked

no but if you leave the key on and unhook the battery then hold down either the horn or breaks to get the remaining charge all cars store even after the battery is unhooked to drain away when either the break lights stop lighting up or the horn stops blowing leave it unhooked with the key on for ten to fifteen min then take the key out and hook the battery back up that should reset it

take a test light and hocke it up in wire for horn under car ground test light.have someone push horn if it does not light work your way back fuse horn button etc it allso a horn realy

Check all fuses and clean battery cables

unhook the battery for about 15 minutes and hook it back up... that should reset it... if your stereo is anti-theft as well... make sure you know the code for it and how to enter it.

pull the old fuse panel away from the bracket and replace them one at a time in the same position to the new one as the old...
make sure the battery is unhooked as well.
