if the horn is already there and is bad, just disconnect the two wires on it, unscrew horn, remove it and reinstall the new one and reconnect the wires. If you don't have a horn, then find a suitable place under the hood and drill X number of holes. The switch is wired in series with the battery and horn. The button is placed at a convenient place you can get to it when you want to blow the horn.
Horn button is a momentary switch. Yours sounds stuck. Check the contacts. Once it grounds, the horn blows & sounds grounded.
You don't have to unplug the horn to replace the battery.
You can replace the horn button on your 1992 Pontiac Bonneville by removing the center steering will cover. Remove the horn button retaining screws. Remove the horn button wiring harness. Reverse the process to install your new horn button.
To wire up a car horn with a button you first need to run one of the wires from the horn to the battery. Take 1of the wires from the horn and run it to where you want the button to go. Connect the wire to the button and that's it.
You may have the wires for your horn crossed with the battery wire. This would cause the horn to go off any time the battery is connected.
On a vehicle, the return path to the battery is through the vehicle's framework. The negative terminal of the battery is connected to the frame of the vehicle. The reason there is only one terminal on the horn is that, that is all that is needed to make the horn operate. Applying the positive side of the battery to the single terminal which is connected to the horn's coil will make it operate. When the horn is bolted to the vehicle this completes the circuit back to the negative terminal of the battery. Apply the 12VDC to the horn by pressing on the horn button which closes the circuit and the horn activates. A horn with only one terminal has its coil grounded internally within the horn. A horn with two terminals has the coil isolated from the ground. On a two terminal horn there needs to be a wire installed to the frame on one of the terminals to make the horn operate.
it is easier to repair the OEM horn assembly than to "rig" up a button
Run a direct wire from the battery to the horn, if it works the problem is in the horn button or the fuse. On second thought, use a test light to see if the horn wire is getting power when the horn button is pressed. If it is, make sure the horn has a good ground. If everything checks out, replace the horn.
check your fuses, find the horn and make sure it is not disconnected.start there then disconnect the wiring from the horn and run apazir of wires from battery to horn hot to hot and negative to negative, toouch to battery see if it beeps if it does then it is probavly the horn button in the stearing wheel.
usually a stuck horn is caused by a bad horn relay.sometimes it is the horn switch itself sticking.even rarer is a faulty horn that becomes stuck. try the relay.
Install an auxilliary horn button on dash board
After removing the airbag, you reconnect battery to test horn.
Check the wiring at the horn contact, if good, jump the horn with another battery to see if they do indeed work. If they do, then the problem is with the contact button. Take it from there.
Cheapest, simplest way is to get a horn button at a parts store and run a wire from the battery to the horn. Just like a large door bell button. Not as convienent as the steering wheel but serves the purpose.
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.
Run a breaker button from horn to car interior to battery
1. remove battery 2. remove battery tray by removing the 2 bolts and 1 nut. 3. unplug the 2 horns and then remove the bracket that holds the horns to the fender well. 4. install new horn(s). 5. reverse steps to install everything back up.
The horn should have two wires going to it. One wire is supposed to be hot (battery voltage 12v). The second wire is open but gets grounded when the horn button is depressed, thus completing the electrical circuit and making the horn toot. So, the first check is: are you getting 12v on one of the two wires? the second check is: when a helper presses the horn button do you get ground to the second of the two wires? The third check is: if you ground the second wire at the horn does it toot? If the first check does not produce 12v, then the fuse is blown or the wire from the fuse to the horn is defective. If the second check does not ground the wire, then the wire to horn button is defective or the horn button itself is defective. If the third check does not toot the horn, replace the horn itself.
Push the car horn button....
Broken Or Disconnected Wire To The Horn. Check For Voltage When Horn Button Is Pushed At The Wire After Removing It From The Horn. On A Vet Probably Not Grounded.
Try unlocking the car doors, its probably the alarm throwing a fit.
first remove wire to horn. see if power is going to horn when horn button is pushed. if it does its a horn problem, if not it is probably in the horn button itself.
the horn is the button in the middle of the steering wheel
