I would check the horn to see if it gets power with a testlight, and try to ground out one of the leads to see if it sounds. It should have power at all times and the button on the steering wheel controls the ground. That can be a source of the problem as well, the button on the steering wheel may not be grounding out the wire to the horn.

Can also take apart the steering wheel until you get down to the horn switch contact and try to ground it out with a screwdriver or test light to see if sounds the horn.

May have to remove the air bag first, though.

The following talks about the steering wheel disassembly:

Steering Wheel Removal & Installation Except Models With Air Bag To Remove:

  1. Disconnect the negative battery cable.
  2. Center the steering wheel so that the front wheels are straight.
  3. If equipped, remove the horn cap from the center of the steering wheel. NOTE: If the horn cap or shroud is equipped with an electrical connector it must be unplugged in order to remove the cap/shroud from the steering column.

  4. Remove the steering wheel-to-steering shaft retainer clip (snapring), then loosen and remove the nut. NOTE: Since the steering column is designed to collapse upon impact, NEVER hammer on it!
  5. Matchmark the relationship of the steering wheel to the steering shaft. Some models may already be equipped with one or more alignment marks. If not, make your own using a permanent marker.
  6. Using a suitable steering wheel puller, such as No. J-1859-03 or equivalent, carefully draw the wheel from the steering column.
To Install:
NOTE: Before installing the steering wheel, be sure that the turn signal switch is in the Neutral position. DO NOT mis-align the steering wheel more than 0.8 in. (20mm) from the horizontal centerline.
  1. Align the match marks and carefully fit the wheel onto the steering shaft splines.
  2. Install the retaining nut and tighten to 30 ft. lbs. (40 Nm).
  3. If equipped, install the horn pad.
  4. Connect the negative battery cable. Remove the horn pad 88458p19.gif

Models With Air Bag To Remove:
These models are equipped with a Supplemental Restraint System (SRS), which uses an air bag. Whenever working near any of the SRS components, such as the impact sensors, the air bag module, steering column and instrument panel, disable the SRS, as described in Section 6.
  1. Disconnect the negative battery cable.
  2. Disable the Supplemental Inflatable Restraint System (SIR). Refer to Section 6 of this manual for this procedure.
  3. Position the steering wheel so that it is in the horizontal position and the front wheel are straight.
  4. Remove the air bag system inflator module as follows:
    • Make sure the air bag system is disabled and the negative battery disconnected.
    • Turn the steering wheel 90 degrees, this will enable you to gain access to the rear shroud holes-to-inflator module.
    • Insert a prytool and push the leaf spring to release the pin.
    • Turn the steering wheel 180 degrees to access the remaining shroud holes, then repeat the procedure to release the pin using the prytool.
    • Tilt the inflator module rearward from the top to access the module electrical wiring, then disengage the wiring from the module and the steering wheel.
    • Unplug the Connector Position Assurance (CPA) and retainer from the module.
  5. Remove the steering wheel retaining nut and the horn plunger contact. NOTE: Since the steering column is designed to collapse upon impact, NEVER hammer on it!
  6. Matchmark the relationship of the steering wheel to the steering shaft. Some models may already be equipped with one or more alignment marks. If not, make your own using a permanent marker.
  7. Using a suitable steering wheel puller, such as No. J-1859-03 or equivalent, carefully draw the wheel from the steering column.
To Install:
  1. Align the match marks and carefully fit the wheel onto the steering shaft.
  2. Install the retaining nut and tighten to 30 ft. lbs. (40 Nm).
  3. Install the inflator module as follows:
    • Attach the Connector Position Assurance (CPA) and retainer to the module.
    • Attach the inflator module wiring to the steering wheel and to the module.
    • Install the inflator module by pressing it into the steering wheel enough to engage and latch all four notched pins in the leaf spring. Make sure the wires are not pinched.
  4. Connect the negative battery cable.

Location of the horn on 2003 Pontiac Grand am. I'm having some much trouble with this matter.

Howdy Mister,

Generally horns are found behind the Front grill..
before the engine compartment...

Usually pretty UNIMPORTANT as most "HORN" issues
resolve to the control switch on the steering wheel.

Find your HORN RELAY and trouble shoot
from there... (my opinion).

Horn is out on a 2003 Mitsubishi Montero limited. What parts needed to fix it?

check horn relay works
get a 12v probe and test the horn switch works when pressed
12v should be supplied to the horn relay coil contact when the horn switch is pushed on.
Also check the fuse.
Check voltage going to horn when pressed
horn might be negatively switched so 12v positive is on one side of horn and relay switches ground negative .
You will find the horn relay under the bonnet in a relay compartment most likely

Horn is not functioning on my 2006 Ford Taurus. I have checked the fuses listed in the owners manual. I however can't seem to locate the Horn Relay. I found a secondary relay box stuck between the battery...

Is the air bag light lit on the instrument cluster ? The horn relay isn't under the hood in the engine compartment , it's in the SJB - smart junction box located inside the passager compartment . Under the dash panel left side . You can take the relay back to autozone because it's not the right one ! The relay is inside the smart junction box ,soldered to the printed circuit board !
Horn Horn
The vehicle is equipped with dual horns. The horns are mounted in the LF frame rail corner behind the front bumper.
The horn system consists of the following components:
  • steering wheel horn switches
  • clockspring
  • horns
  • smart junction box (SJB)
Horn Switch, Steering Wheel Mounted
The horn switches are incorporated within the driver side air bag module in the steering wheel. The switches are grounded and control the horns through the clockspring. For removal and installation of the driver side air bag module, refer to Section 501-20B .

2001 f-150 ford pick up truck . horn will not work

Did you check the fuse for the horn ? Engine compartment fuse panel, fuse #7, 20A

You can pull the horn relay, and jumper the normally open contacts to see if the fuse, horn and grounds for the horn are in working order ( this operates the horn without needing to use the horn button ).
The Horn relay is a half size Ford ISO relay in the engine compartment fuse panel ( check your owners manual to locate relay 206 ).

Diagram to jumper the horn relay, with this in place, the horn should sound as long as the jumper is in place

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

Am trying to find out were the horn fuse is

The fuse box is behind the glove box. You might have to pull the glove box past the stops to access the fuses. The 15 amp horn fuse should be there. There is also a horn relay, which is usually located in the engine compartment relay box. Please see my tip if you want to check the relay socket:

Horn is stuck cant find the damn thing or the horne relay sounds like its on the left side of the engine compartment short cut fix was to pull the horn,s 15a fuse in the cab

under the hood in the fuse box all the big square ones are the relays. activate the horn again then remove them one at time to locate the horn relay, when found rotate with known good one. If this doesnt locate the problem the then problem is in the steering wheel.

Horn does not work 1998 Chev blazer

It sounds like a problem with your horn relay or fuse...

When looking for relays, the most common spot is in the relay fuse compartment under the hood, either near the battery OR near the firewall2.gif in most instances.

However when troubleshooting2.gif any electrical problem, checking all fuses in both the passenger and engine compartment is crucial before moving on.

Use your owners manual or a Haynes or Chilton manual to determine which fuse is resonsible for which circuit or the information is usually located on the inside of either compartment cover

No horn on my '95 Grand Marquis. I have the owner's manual and one place it says location #5. Then on page 341 it doesn't list #5. Found other wrong references. How do I fix the horn? Fuse in #5 looks...

Your horn works off of the engine compartment fuse box. There will be Maxi fuses and regular fuses in it. The regular fuses there is one 15 amp fuse that fuse is for your horn relay. I don't know what direction they go in but it will be the 5th fuse in that row. Right next to that row of fuses there will be a row of Maxi fuses they should go in this order a 50, 50,40,30,50,40,30. In this same direction of fuses the # 2 relay in this order is your relay for your horn. If you remove this relay you should have 12 volts on 2 of these wires. There should only be 4 pins that are used in that relay even though it has for pins. The 2 power wires both work off of the #5 i5 amp fuse in the engine compartment. If you have power on 2 wires at the relay when it is removed then you will need to chack all the other wires where the relay is for a ground when someone holds the horn button down for you to check. If you have a ground when the horn button is depressed then the other terminal that is left in the relay that you removed I need you to take one of the power wires that has 12 volts and jump it over to that other terminal that is n't the ground wire for your horn when the pad is depressed. If the horn goes off then every thing is ok with that circuit then the relay has probably failed switch it with a simular looking relay in the engine compartment fuse panel then see if your horn works properly. If you don't have a ground at one of the terminals when someone holds the horn pad down. Then the problem is probably between the horn pad and the relay more then likely it is your clock spring in your steering column. Let me know if you need any more information then this.
