Where is the horn relay located on a 2007 ford edge sel


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 .
Symptom Chart Condition Possible Sources Action
  • The horn is inoperative
  • Fuse
  • Circuitry
  • Horn
  • Clockspring
  • Steering wheel switch harness
  • Horn switches (part of the steering wheel)
  • Smart junction box (SJB)
  • Go To Pinpoint Test A .

My 1998 acura cl 2.3 horn stopped working. Its not the fuse. You can still hear it clicking when you press the steering wheel?


There's a good chance that it;s the relay.
If you open the hood and have someone press the horn switch/ steering wheel while you listen under the hood,you should be able to determine which solenoid it is. A voltage meter will let you check the function.
Don't know if the door light is related. Unlikely.

97 cavalier horn stopped working. Fuse is OK. I hear no clicking noise when I press the horn. Other that a bad horn or a loose wire to the horn, what else might be the problem?


There are tow things other than the gorm that could be bad. The forst (And most likely) is the horn switch located in the steering wheel. These are fragile and easy to break, and not to easy to replace. If you find that the switch is the problem, you would be better served to mount an external horn switch on the dash near the driver. This is legal for inspection in most states (check with your local inspection authority first). The otherr item that could be bad is the horn relay. It is located under dash on the passengers side kickpanel near the glove box. it is mounted in a relay panel there. You should hear it click when preesing the horn switch if the car is quiet enough.

2002 VW Beetle 1.8T\r\nRemoved horns and tested using battery & the both worked, reinstalled & press horn on steering wheel & nothing just hear a clicking noise from where I pushed on steering...


Generally the steering wheel boss switch does not wear out (the horn is not over used!). I would check the fuses and then the relay and if they look OK check the wiring form the relay to the horns for continuity. Use a voltmeter to check that voltage is being supplied to the relay when the horn switch is pressed. Then check that voltage is being output by the relay in response to this voltage input. If this all looks OK then there is some kind of break in the wiring to the horn unit

Horn want work


Check the horn itself by running a wire from the positive lead of the battery to the connection spade on the horn. If it works, you may have a bad horn relay or the problem may be in the steering column.
If you have air bags, DO NOT attempt to work on the column unless you exactly follow directions for that found in either haynes or chilton manuals. Otherwise, your air bag may deploy and hurt you.
If the air bag light on the dash is on, chances are that the "clock spring" in the column has failed.

How to fix horn


First go to horn, its in the right side (passenger side) very front behind bumper. Turn wheel to the right, remove inner fender well, locate horn. Check to see if you have 12V there when the horn is activated to ensure its not just a horn. If there is 12V and ground and horn doesn't sound, you'll need a new horn. If voltage is good then back track to the horn relay, it should be under the hood electrical center (some earlier models were under the dash below steering wheel. If you press on the horn in the steering wheel, you should hear it click to locate. If not check the black wire going up the steering column, when jumpered to ground and horn sounds then the problem is inside the steering wheel, horn ring or contacts on the pad are faulty.

Bought an 2004 honda accord and the horn does not work. What is the procedure for repairing this issue?


simple circuit, but can be hard if problem is switch in steering wheel. First check fuse and relay at fuse box. relay should click when horn button on wheel is pushed. If relay doesn't click, either button or relay is bad. If relay clicks, test for voltage at horn. You can use a simple test light available at the auto parts store if you don't have a voltmeter. If there is voltage at the horn, replace horn.
If relay does not click, replace relay to see if that fixes your problem. If new relay doesn't fix, you have a bad switch in the steering wheel or possibly bad wiring. cannot help you with switch as it's different on every car. any questions--let me know.

I have a 2006 dodge ram p/u. My problem is that when i press on the horn button, the horn will blow 1 short burst and then stop sounding. Everytime I press the horn button it will blow a short burst and...


this is not a horn relay issue. In most cases this problem is caused by the rotating ribbon circuit contact under the steering wheel having a broken filament, the part is known as a clock spring contact, u will need to properly disarm the airbag and remove the steering wheel to access the part. WARNING: Failure to follow factory Airbag disarming protocol can result in an unexpected Airbag deployment and possible serious personnel injury

1996 Saturn SL. Horn doesnt work. Fuse is ok. Can't find horn under hood.


it is behind bumper drivers side. I believe there is a relay in the horn, making the horn unique and origional replacement required. if it has three wires in it then it has built in relay.

Horn will not sound from steering but okay otherwise


you need to Check the Wire inside the Steering wheel, When Grounded by pressing horn button the relay will send the 12 volts to Horn,

You Also could and Please Re-check the Color of wire for the Horn SHOULD be a Black Wire in the wire loom Under the Dash on the Column and If you Ground down the Black wire from Under the dash, You would Find out If it is In fact the Steering wheel it self,

you could also add a Second Button on the Dashboard

black wire to Button and then to Ground body,
