if its clicking then its the horn itself.you can get a horn from auto parts stores.
My horn does not work either. My 2002 has 64000 miles so it shocked me when I bought it and the horn did not work. Get someone under the hood while you press the horn. If it clicks then it works. The horn is behind the right headlight. Remove the headlight and replace the horn. If you know how you can check the voltage to make sure it is connected properly. I had to but then I had front end damage and I did not trust the repair shop to have it connected.
One side of the horn probably has direct power, and the other side is the switching side. So when the horn button is pushed, the relay connects the horn to ground. Check the relay it is most likely bad.
fix it.
The horn relay is under the airbag in the steering wheel. Best to let Saturn dealer fix it.
The horn button contacts on the steering wheel are dirty.
it depends what is wrong with it....start by figuring that out. It doesnt work. Thats whats wrong with it.
might be a fuse, check the fuse box in the drivers footwell
Many times the horn itself could be bad; if you have power to the horn and no sound, replace the horn. I would get one from a salvage yard for $10-15. Roll down window. Hollar real loud "LOOK OUT!"
What year is this vehicle? The horns are pretty bad for corrosion due to moisture around 1996-1998. A lot of the time the horn shorts out and takes the horn fuse under the hood with it as well. You made a horn and a fuse. Check the connector to see if it is green from corrosion.
Blown fuse, defective fuel pump relay, or the pump itself is defective.
pop the hood and in front of the radiator there is a circular device. that is your horn. check the connection of the wire to the receiver on the horn. when that is secure, use a flathead screwdriver to pry the cover off of the steering wheel and check that connection. if those are both secured and horn still doesnt work, check the fuse for your dash.
I have found that on my sL1, the reason that the horn didn't work is because the horn is located in an area where water and moisture collect. this has caused the 1 terminal to completely rott off. I removed the clip that connects to the horn, which is a 3-wire plug, and i noticed the hot terminal was completely broken. there was corrosion. I replaced the horn and it was fine.
