Where is the horn relay switch located at - 2002 Lincoln LS

The horn system consists of a single horn, a horn relay located in the underhood fuse block, and driver controlled horn switch in the steering wheel. The horn system is designed to provide the driver with an audible warning to signal pedestrians, other drivers, etc.
Operation
Voltage is supplied to the horn relay coil and contacts at all times through a 10 amp HORN fuse, located in the underhood fuse block. When the driver pushes the horn pad, driver air bag module, the circuit completes and energizes the horn relay coil. This causes the horn relay contact to close. When the contact closes, current travels to the horn and the horn emits an audible warning.

It is located in the SJB - smart junction box an it is a non- serviceable part . soldered to the board inside . Where do you hear the clicking noise coming from ? The SJB is located behind the left side kick panel .
SECTION 413-06: Horn 2007 Edge/MKX Workshop Manual DESCRIPTION AND OPERATION Procedure revision date: 10/30/2006 Horn The horn system consists of the following components:

• Horn switches (part of the steering wheel)
• Clockspring
• Horn relay (part of the smart junction box [SJB])
• Horn

For removal and installation of the steering wheel, refer to Section 211-04 .
For removal and installation of the SJB, refer to Section 419-10 .
Principles of Operation
The smart junction box (SJB) supplies the control and switched voltage to the horn relay (part of the SJB). When the horn switches (part of the steering wheel) are pressed, ground is supplied through the clockspring to the horn relay. The horn relay is then energized directing voltage to the horn and enabling the horn to sound. When the vehicle security system is armed, the SJB provides a momentary ground to the horn relay control side to indicate the system is armed, and an on and off ground when an intrusion is detected or the panic alarm is activated.
If your horns are not working ,you have a wiring problem or the clock spring is open . If the relay is bad the whole SJB has to be replace an the dealer would have to do that . Needs to be programmed ,with factory tool .

You

What is the problem with the horn. Check Fuse for Horn. Check Horn it is located under the bonnet. Near the front grill of the car. Check relay for horn most likely also located somewhere in engine compartment in a plastic box compartment with numerous relays. If horn not sounding should hear relay click when horn button pressed.
If horn is getting voltage at horn plug (positively switched horn design) then horn may need replacing.If negatively switched then horn connects to body of car when button pressed and other side of circuit has Plus 12 volts always on it.

There is a relay for the horn, too. You can simply unplug that.

You didn't define your vehicle. Check the owner's manual for fuse locations.

Horn relays are found under the hood in a fuse/relay enclosure. The horn switch on the steering wheel is part of a low-current circuit that activates the horn relay. That circuit's fuse will be located in the interior fuse panel, wherever that is hiding!

Could be either the relay or the horn switch not making contact

as with all elect. fails check all fuses
in this case the 15 amp fuse marked, HORN
can i presume all else works good> car drives.?
all answers, USA spec car. nobody ever tells location, so..... if not USA< all answers wrong. the usa car has just 1 horn.....
got voltage to horn? 12v
Yes or no.?
if yes horn bad.
got voltage from horn relay
yes, bad wires.from, relay to horn
no, got voltage 12v to horn relay coil,
yes, good, no bad fuse.
got 0v to other relay coil (all tests honking)
yes, bad relay.
no, bad horns switch.

if you want me to guess. sure.
1: bad wires ../connections, end to end.
2 bad horn
3: bad relay
4: bad horn switch.

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 .

I have a 2013 toyota yaris le bought a oe universal horn apparently the horn wasnt getting good ground so i bought a wire added it to the battery and the horn went off i was happy until i realized it wouldn't stop. Wherr is the relay to make it only work when touched. Help

the explorer has two horns, they are both mounted under the driver's side headlight behind the front bumper. you will need to remove the splash shield to get to them. Hope this helps you

The dealer can hook up his diagnostic tool and retrieve the fault code. -------------- SECTION 413-06: Horn 2003 Expedition/Navigator Workshop Manual DESCRIPTION AND OPERATION Horn Horn components include the following items:

• clockspring
• horn relay
• horns
• steering wheel pad horn switch

Horn switches The horn switch is incorporated into the driver side air bag module in the steering wheel. The switch is powered through the clockspring and grounded through the steering column. For removal and installation of the horn switch, refer to Section 501-20B .
Horn relay The horn relay is incorperated into the central junction box (CJB). The central junction box is located behind the passenger lower kick panel.
