Check the horn fuse first, followed by the horn relay. If both of these are ok then the horn button or the horn are bad.
Check the fuse!
turn signals work butt the brake lights dont can anyone help please? cant afford a mechanic.
any horn will work from the junkyard.
If the horn does not work on a 1996 Oldsmobile Ciera, you can replace the horn. Almost any type of horn should be compatible.

If the horn does not work in the 1998 Chevy Prism and the vehicle was purchased used in this condition, it is quite possible that the previous owner cut the horn wires to stop the annoying security alarm. It is also possible that the fuse for the horn is blown.
It depends on the exact problem. If it's that both brake lights in the back do not work and the middle one works, it could be your turn signal switch.
Possible bad stop light switch located near the brake pedal.
ON THE STEERING WHEEL!!!! (Okay sure). the actual horn module that makes sound is under the hood. the wire is attached to the airbag. remember when your doing work near the airbag or with the airbag to disable it.
There are several things that can cause your Chevy Lumina fan to not work properly. The most common cause is a bad ground wire. Check the ground wire and make sure it is tight and free of corrosion.
