So you have replaced the single horn and it still dosen't work ? both horns or just the one? The reason why the horns are grounded separately is the reason that both horns can operate without the other. double check that ground.

Removed the only wire connected to horn it now is only held and connected to frame by a single bolt. Afraid to wire in air horn because horn still sounds even though it has no wire connected to it.


Hi Christian:
Many vehicles have 2 horns so that the sound is more pleasant. If there is no wire connected to a horn, it can not (in my experience) make any sound. May I suggest that you have someone assist you by tapping the horn button while you locate the horn that is sounding.

Subject: How to check an inoperative horn
Customer's exact description: ...the horn on my 1995 Buick LeSabre does not work...how to fix?
Here's how it's done:
Step 1. Start with the pre-check:

Do a Thorough Visual Inspection
Do a thorough visual and "hands-on" underhood inspection before starting any diagnostic procedure! You can find the cause of many problems by just looking, thereby saving yourself a lot of time. • Has the vehicle been serviced recently? Sometimes things get reconnected in the wrong place, or not at all. • Don't take shortcuts. Inspect connectors and wiring which may be difficult to see due to location.
Step 2. Instructions:
One. Remove the horn relay and check for battery voltage at the relay connector terminals.
  • If battery voltage is present at both terminals, go to Two.
  • If battery voltage is not present, check the ORN wiring and the relay fuse for circuit.
Two. With the horn switch depressed, measure voltage from the relay terminals. Wear hearing protectors, if someone is assisting you and depressing the horn switch while you're under the hood.
  • If voltage is present, go to Three.
  • If battery voltage is not present, check the black wire for an open circuit; check the connectors for proper terminal contact; check the in-line connector for proper terminal contact; check the spring loaded contact, slip ring, and horn switch for an open circuit.
Three: Connect a fused jumper from relay connector terminal 30 to terminal 86.
  • If the horn does not sound, go to Four.
  • If the horns sound, replace the horn relay.

Four: Disconnect the the suspect horn connector. Connect a fused jumper from the suspect horn terminal B (dark green) to the positive + battery terminal.
  • If the horn sounds, check the wiring to the horn relay for an open circuit or short to the ground.
  • If horn doesn't sound, check the black wiring for an open circuit, if OK, then replace the horn.

All the best,
Ben

Horn honked randomly but is now constant. I have disconnected both wire connections at the 2 horns. Since as soon as one is connected, the horn sounds. How do I properly identity the voltage horn wire...


If you take the steering wheel off you'll see the ground wire that grounds the constantly connected horn. Note the color of the insulation.

You could also reroute the wire from under the hood starting at the horns and simply connecting a switch that grounds the horn out to operate it with an outside switch, that is outside of the steering wheel.

1995 LeSabre: Horn honking randomly. Is there a way to use the existing horn and run a wire to a separate switch to the inside of the car? The cost to replace the switch is too high since it located in...


You can by-pass the horn pad on the steering wheel and install an after-market Horn Button to operate the horn, and you can purchase an after-market Horn Button from most auto part stores for under five dollars, and there are a few different designs that you can choose from.

You will also need enough ground wire to wire the horn button into your vehicle, and most likely a few wire connectors, and that can all be figured out once you actually see the Horn Button that you purchase.

To install the Horn Button:

First locate the turn signal switch wire connector and it should be on the lower right side of the steering column.

Then locate the Horn wire, it will have battery voltage at the wire and when the horn wire is grounded the Horn will operate or sound, and usually GM used a Black wire with an Orange stripe for the Horn wire at the vehicle wire connector for the turn signal switch from the vehicle wire harness, and the wire usually changed to a solid Black wire on the wire connector from the turn signal switch. However that is not always the case, and the wires should be tested to be certain of the Horn wire.

You can connect a test wire to a good ground and quickly make contact with the wire that you are testing and when the Horn sounds then you have found the right wire. (make contact for only a second and do not ground the wires that you are testing for more than a second or you could blow a fuse)

Once you have successfully located the Horn wire, then on the wire connector from the turn signal switch, cut the horn wire about three inches from the wire connector for the turn signal switch. (or at least enough to connect a wire to the cut Horn wire from the turn signal wire connector)

The rest is simple, you just connect one of the wires from the Horn Button to the cut wire from the turn signal wire connector, and then connect the other wire from the Horn Button to a good ground, and then test the operation of the Horn Button, and if the horn is working with the new Horn Button then mount the Horn Button where you want it to be and the job is complete, and you should then have a fully functional horn again.

I have made you a wire diagram to help assist you, but it is only for a referencre and the wire colors might not match, so be sure that you actually test the wires to find the actual wire for the horn. Let me know if you require any further assisance.

Hello, Just bought a 2000 Buick Regal, horn


Take the horn button assembly apart--there should be only one wire there (goes to the horn relay) and not be grounded. It goes to the insulated metal part that grounds the plate when button pushed. Unfix the grounded wire and see if horn is quiet. You may need to replace that wire if it still sounds.
