Horn wont work when I put new horn on - 1998 Isuzu Rodeo

If the fuse blew, most likely the new one you installed also blew. Check it again. You have a short somewhere. Double check all the wires you did while installing the horn button.

start by checking fuses and horn relay, next check the ground on the horn it self, and if it still wont work you may have to change horn ,to check horn just put power to where horn power would go to it ,it should blow .

Under the steering wheel. If the clock spring is broken the horn wont blow, the cruse wont work and the air bag light stays on.

Hi. It sounds like the steering lock has not been put back into position properly. This would need reassembly.

I have a 94 Kia sephia and had the same issue try unplugging the timing control box located above the fuse box my car runs perfect and doesn't try and make me look like I'm stealing it anymore. Sincerly Alex.

Actually the horn relay on this one is in the dash next to the flasher. This is to the left of the steering column if you are sitting in the driver's seat. It's kind of behind the dimmer switch.

check under the bonnet for a fuse box near the battery and check the big fuses in their and the connections

First if brake lights arent working then the shiftlock wont work. Works off of same circuit. I would check fuses for brake lights and also horn. Not exactly sure on the 92's but good chance theres fuse's inside car and also under hood.

Maybe horn became unplugged. Put 12 v power to horn make sure horn works. Put test light on terminal on horn have someone press the horn button, if light comes on and horn does not blow you may need new horn. if light does not come on you may have bad contact at horn button, blown fuse, broken wire, bad horn relay or possibly just a bad ground.

well you have two choices you can run a new cicruit which means you need a wire to a fuse and then a wire to a switch and then to the horn and then ground and that will be some work. your other choice is much simpler. find where the old horn is and change the connector to fit the new horn. remove the old horn and replace the new horn in the old spot and ground the horn if you need to since some have a one wire and a body ground so you wont need to hook the ground to anything but the bolt if you need to do that.
