About four things to do, first check voltage at horn with key on and button pressed. If voltage there try moving the small gap screw back and fourth a few times. If that doen't work replace horn. If no voltage check fuse and horn relay, you should be able to hear the relay click when you push the horn button, If not and fuse is ok. Switch relay out with another on on the car. If that doesn't fix it check the horn button for continuity.

Sun visor lights,... remove the sun visor clips you will find a copper insert inside the clip if this has broken (they do) you will need to replace them they 're about $12-15 ea. put them in & open your mirror "Gorgeous"
For the horn check the wire leads on the horn they are probably loose

Horn and heater may be fuse related. The headrests have nothing to do with fuses. The switch is bad or going that way for the seat or the motors for the headrests are out.

The horn fuse spin it, or replace as corrosion from aluminum fuses cause problems. I suggest replacing them all with new copper barrel fuses. The blower motor fan is a strip fuse on the driver side strut mount in a tootsie roll sized case.

The first thing a Tech (or I) would do in this case is check the BCM (body control module) for a fault code related to these issues. A scan tool will be needed to start this procedure. Otherwise, to guess at a cause would not be a cost effective or correct approach for diagnosis. Your vehicle has many circuits and control modules that control these accessories, and scanning the system will help pin point a solution.

My horn isn't working on a Chevy equinox but it's a new horn. What could be wrong with it..and my cruise control don't qork. Is it my steering wheel?


Was Cruise Control working before the New Horn was installed? The power supply to the Horn, (input to ground wire) is connected to the Cruise Control Module (CCM). This CCM is wired to the Relay Switch Box located in the Engine Bay. The Relay Box cover will have a Chart indicating what function each Relay coresponds to. Your local autoparts store (AutoZone) can test the Relay Switch, and you'll know (if any Relay) need to be replaced.

The CCM is also wired to the Steering Wheel, but first passes through the Clock Spring Coil, located just behind the Steering Wheel. The Clock Spring allowes for the Function Buttons on the Steering Wheel to have power while Steering Wheel spins.

The Clock Spring can malfunction or break, its rare, but this will cut power to the Function Buttons on Steering Wheel. If ALL the buttons on Steering Wheel dont work, then the Clock Spring is the Culprit. The Coil may need to be replaced.

The Cruise Control Module itself may have failed and also would cause a few or all Steering Wheel Functions to quit working.

But first check the Relay Switch Box and examine the Harness Cables connecting (Steering Wheel--to--CCM--to--Relay Switch Box--to--Battery Supply).

Also if Cruise Control was working before the new Horn was installed and now not working, then most likely the Problem is a bad wire connection somewhere and/or is a faulty Relay.

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 .

2007 cobalt horn relay location


The relay is located in the under hood fuse / relay box . Marked HORN PCB relay , If you change it out an horn still doesn't work ,you can test to see what is missing right at the relay . Two of the pins at the relay socket should have battery + , one should be open an the other should show ground 0 ohm's . If you look on the side of the relay there is a diagram of the pins. 30, is Battery +, 87 goes to the horn . When you push the horn button on the steering wheel it causes the relay coil to energize closing the contacts in the relay sending power from pin 30 to pin 87 down to the horn turning it on ! Pins 85 an 86 are the control side , one should have battery + an other should be open , till someone pushes the horn button . You can test for power with volt meter an test with ohm meter for ground on the one , an a open on the other one, an have someone push the horn button an it should change to 0 ohm's .

Location horn relay on 82 cj7


The horn relay primary receives + full time and is actuated by receiving ground (-) from the horn button. Check ground continuity at the horn button (at the steering wheel) to make sure it is working first (most likely culprit). If the horn button is working, check to see if the horn relay is working (second most likely culprit). To test the horn relay, provide chassis or battery ground to the (-) primary terminal of the horn relay and see if the horn honks. If it does, that will tell you that the problem is in the wiring between the steering wheel and the relay, most likely a disconnected wire at the steering column.
The only other components in the system are the fuse for the horn circuit (if you have 12v at the horn relay, that is fine), and the horn itself. My bet is on the horn button pad itself.

When driving, my horn on my 1999 Chrysler Cirrus blows randomly and will not stop until I hit repeatedly in the center of steering wheel. What can I do that is cheap and quick to stop this?


I have or should say had same issue on 1996 cirrus quick fix just remove the HORN RELAY located on the left side of dash relay only controls horn. To really solve the issue at hand you must replace the clock spring on the steering wheel dis-arm air bag before messing with steering wheel to avoid activation of air bag disconnect battery for 10 min then its safe to fiddle with steering wheel safely.

  • The horn relay might have welded contacts (stuck in the on position). Pulling the relay should stop the horn.
  • The wiring harness on the steering column might have a broken wire to the horn relay shorting to someplace that applies power to the relay. In this case, turning the steering wheel all the way to one side or the other may stop the horn, and it won't sound when you press the horn button.
  • The horn button in the steering wheel is stuck on or shorted.

Horn not working


Horns have power to them all the time. When you push the horn button, you are completing a circuit by providing a Ground.


Before the horn gets it's power for the 2003 Pontaic GrandAm, the power goes through a Horn Relay. (Number 21 relay)

It may be a bad relay, horn slip ring contact button, (Located under steering wheel), or bad horn/s.

The horns are located up under the front air dam, tucked up close to the air conditioner condenser. VERY hard to get to.
