Question about 1999 Chevrolet Lumina

Trouble diagnosing horn

I am having issues diagnosing why my mom's horns are inoperative. I have done the following:

1. Checked the horn fuse.
2. Checked that the horn relay "clicks" with a 9-volt battery across the coil terminals. Also checked continuity across the other two switched terminals when energized. Relay operates as expected.
3. Checked voltage at the relay receptacle when the steering wheel is depressed. I get 12V at the relay coil terminals.
4. Shorted the terminal on the relay receptacle with 12V and the horn honked.

So I seem to have verified that all of the components and individual circuits are operating properly, but the system as a whole is inoperative. Any suggestions would be greatly appreciated.

Regards,
KH

Make sure you have the ignition on or the car running and try again----if she has remote locks or starter does the remote sound the horn?

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 .

The horn does not work at all on 1999 escort


I am assuming you have checked the Fuse Box under the hood for the Horn Fuse and / or the Horn Relay and made sure both are good?

You can always try the steps outlined in this video to replace the horn pad. to see if this is your issue if you have exhausted all of your other resources.

Or You can try these steps to further diagnose your issues:

The horn relay on ZX2's is located underneath the dashboard on the drivers side. There are several relays located there - identify the horn relay by the "clicking" sound it makes when the horn is pressed. The likelyhood that you have a bad relay is minimal. Start by checking the horn fuse (the fuse box is located under the dash on the driver side). Next, check the relay. If the relay is making a clicking noise, it is probably OK. The next thing to check is the horn itself. it is located on the passenger side of the vehicle, up underneath the front bumber. Most instructions say to remove the bumber cover to get to the horn, but this is not neccesary. In my experience with Escort horn problems, the problem has been with the horn "switch", a wafer thin piece of plastic that lies between the steering wheel cover and the airbag assembly. Below are instructions for replacement of this switch - don't be intimidted by the procedure - it is not difficult.

You cannot buy a horn switch at a dealer - they tell you that the horn switch is part of the airbag assembly, which cost $450 plus. Understandably, Ford doesn't want people "messing around" with airbags. Go to a junk yard - you can eazily find and remove the horn switch from an Escort who's airbags have already deployed. I bought two of them for $5. Identify and remove the junkyard horn switch by reading step 7 below. This is an eazy fix if you follow these instructions. Should take about 10 minutes. I replaced my "stuck" 97 Escort horn switch as follows...
1) Disconnect negative battery cable, wait for at least 1/2 hour for residual power discharge before proceeding to net step (IMPORTANT!). This will disable the airbag. Neglecting this step could cause serious injury or death!
2) Remove two 10mm bolts directly behind the steering wheel - one on left, one on right. These secure the airbag unit.
3) carefully lift the airbag unit out of the steering wheel.
4) remove two small star-screws at bottom of airbag unit using star end screw driver - the horn wires enter the airbag unit next to these screws
5) pry the airbag cover (this is the front part of the steering wheel cover with the horn picture on it) off of the plastic tabs of the airbag unit, on the left & right sides - should come off very eazily.
6) now you can lift the airbag cover up (there are three rivets that continue to hold the top portion of the cover in place)
7) the horn switch, which is covered by a thin layer of dark foam, is a very thin plastic pad with two wires coming out (same wires as step 4). You can see wafer thin copper strips inside the plastic. The switch is held in place by three small plastic tabs. Remove the switch and disconnect the wires at the red connector inside the steering wheel.
8) replace horn switch with junkyard switch
9) re-assembly is the reverse of the removal.
This procedure should apply to 97 through 2002 Escorts, including the ZX2. Hope this helps someone save some money.

2002 Ford F-150 regular cab. Went to get it inspected for licensing and the horn does not work. HELP with instructions would be appreciated. Thanks


1. Did you check the fuse for the horn ?
This is Engine Compartment Fuse # 7 ; 20A

2. You can pull the Horn relay and jumper the normally open contacts ( as shown with the red line below ) to activate the horns without using the button.

If this does not work, either the fuse is no good, or the ground at the horn connector is no good. Replace the fuse or test the ground on the horn connector with a meter ( set to ohms ) to the battery neg terminal.

If this does work, using a meter ( set to ohms ) test from pin #2 in the relay socket ( as shown above ) to the battery neg terminal. When you press on the horn button, you should have a low resistance ( The test steps will stop you from paying for basic trouble shooting issues.
