Check to see if there is power going to the horn. Take the wire off the horn and have someone push the horn button and see if you have power at the wire. You may have to turn the ign key on. If you have power then make sure the connector is not corroded on the horn AND wire and you might untighten and wiggle the horn and then retighten the bolt that holds the horn on to make sure you have a good ground, if they checked ok then the horn is bad. They are not that expensive to replace. If there is no power then check the fuse. If the fuse isn't blown check to make sure the fuse holders aren't corroded. If every thing is fine then the problem may be in the horn button area or you have a broken wire. You'll have to get the Bentley manual for your year bug as they all differ slightly on different year bugs.
The fuse. A shorted horn can cause the fuse to break.
The horn relay is under the airbag in the steering wheel. Best to let Saturn dealer fix it.
The horn sits under the front of the car, and it's bolted to the "frame". Undo the wires that are on the old horn, and remember where the came from so you can put them in the same order on the new horn. If you have the correct horn, the same wiring configuration should work, and you just bolt it on.
cuz there broke.. try flasher or turn signal
You have two problems. The horn that doesn't work when you hot wire it is bad. The other problem could be a blown fuse or the horn contacts in the steering wheel are dirty and not making contact or the horn relay is bad.
Check your car fuses.
check fuses eaither that or dont do something you dont know how to do like jump a car. Id take it somewhere if you cant jump a vehicle you cant work on your car.
run a wire straight from the battery to the horn. if it dont honk that way, the horn is bad. get a new one. It may also be the horn contacts in the steering column, If running a strait wire don't work and a new horn don't work, that will be your problem, but try the wire first, Its cheeper.
If it is the same as my 68, the horn button is held in place by a rubber o-ring under the button. carrefully work a thin, flat screw driver under the edge of the horn button and TWIST. Be careful not to chip the button. This should pop out the horn button.
from what ive read you can switch the starter relay with the horn relay and give it a try.... if she starts and the horn dont work you have a bad relay
then your horn is fine.
If the horn does not work on a 1996 Oldsmobile Ciera, you can replace the horn. Almost any type of horn should be compatible.
