Horn not working

Ford dealer, or ford super start tester can check the clockspring, both horn and cruise wires go thru it...

Thank you I'll have to try that

Let us know how you make out...

I will as soon as I find out how much it cost to check it out...I've waited this long alittle longer shouldn't hurt. Thank you so much for your help.

If you are brave enough, here's how to check it yourself... TEST G: HORN INOPERATIVE 1. Disconnect horn relay from battery junction box. Measure voltage between ground and horn relay socket terminals No. 1 and 3 (both Yellow/Light Blue wires). See Fig. 8 . If battery voltage exists, go to next step. If battery voltage does not exist, repair open in Yellow/Light Blue wire between horn relay and battery junction box. See WIRING DIAGRAMS . 2. Check horn relay. See HORN RELAY under COMPONENT TEST. If horn relay is okay, go to next step. If horn relay is defective, replace horn relay. 3. Measure resistance between ground and horn relay socket terminal No. 2 (Dark/Blue wire) while pressing horn switch on steering wheel. Resistance should be 5 ohms or less when horn switch is pressed and greater than 10 k/ohms when released. If resistances are as specified, go to next step. If either resistance is not as specified, go to step 6 . 4. Disconnect horn 2-pin harness connector No. C131. Horns are located on right side, behind front bumper. Measure resistance in Yellow/Light Green wire between horn relay socket terminal No. 5 and horn harness connector C131 terminal No. 1. If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Yellow/Light Green wire between horn relay and horn. See WIRING DIAGRAMS . 5. Measure resistance between ground and horn harness connector C131 terminal No. 2 (Black wire). If resistance is 5 ohms or less, replace horn. If resistance is more than 5 ohms, repair open in Black wire between horn and ground, Ground is located on right side of radiator support. See WIRING DIAGRAMS . 6. Deactivate air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. Disconnect horn switch 2-pin harness connector. Measure resistance between horn switch harness connector terminals. resistance should be more than 10 k/ohms when horn switch is released and 5 ohms or less when horn switch is pressed. If resistances are as specified, go to next step. If resistances are not as specified, replace driver's side air bag module. See AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS. 7. Disconnect clockspring 6-pin harness connector C218b. Measure resistance in Dark Blue wire between horn relay socket terminal No. 2 and clock spring harness connector C218b terminal No. 5. See Fig. 6 . If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Dark Blue wire between horn relay and clockspring. See WIRING DIAGRAMS . 8. Remove driver's side air bag and disconnect upper clockspring 5-pin harness connector. Measure resistance in Dark Blue wire between clockspring harness connector terminal No. 5 and upper clockspring harness connector terminal No. 3. Measure resistance in Dark Green/Orange wire between clockspring harness connector terminal No. 3 and upper clockspring harness connector terminal No. 4. See Fig. 6 . If resistances are 5 ohms or less, go to next step. If either resistance is more than 5 ohms, replace clockspring. See CLOCKSPRING under REMOVAL & INSTALLATION. WARNING: Vehicles are equipped with air bag supplemental restraint system. Before attempting ANY repairs involving steering column, instrument panel or related components, see AIR BAG SAFETY PRECAUTIONS and DISABLING & ACTIVATING AIR BAG SYSTEM in AIR BAG RESTRAINT SYSTEMS article in RESTRAINTS.9. Disconnect speed control servo/actuator 10-pin harness connector C122. Speed control servo is located on left side of engine compartment. Measure resistance in Dark Green/Orange wire between clockspring harness connector terminal No. 3 and speed control servo/actuator harness connector terminal No. 6. See Fig. 6 Fig. 7 . If resistance is 5 ohms or less, go to next step. If resistance is more than 5 ohms, repair open in Dark Green/Orange wire between clockspring and speed control servo/actuator. See WIRING DIAGRAMS . 10. Measure resistance between ground and speed control servo/actuator harness connector C122 terminal No. 10 (Black wire). If resistance is 5 ohms or less, replace speed control servo/actuator. See SPEED CONTROL SERVO/ACTUATOR under REMOVAL & INSTALLATION. If resistance is more than 5 ohms, repair open in Black wire between speed control servo/actuator and ground. Ground is located on rear of right front fender. See WIRING DIAGRAMS . 11/24/2009 ...

The horn relay is in the battery junction box under the hood, heres the legend:

I might be brave enough...Just worried the air bag going off. Thanks for all the info.

Remove negative battery cable for 2 minutes, SRS is now disabled...

That dark green wire goes to the ABS control module near the radiator, if ABS works it's not a concern, test the circuits as described in last post! Does instrument cluster work right? I am talking about the wires at the bottom of the steering column for the clockspring...colors are given...
This is the answer to your email:
Hey Mike,

I tried to ring the dark green wire from the Instrument Cluster back, I found it in the firewall penetration but it runs into a bundle back to the PCM. There are two green wires, one goes to the aux fuse panel above the PCM and the other runs into a ten pin connector by the radiator. Neither of these two wires gives me continuity but I don't know which to replace. I would like to not have to cut the bundles apart if possible but if I have to I will. Any assistance you could render would be appreciated.

Thanks for all you help ---- Jeff

Where is the horn located and how do I replace the horn in my F150?

Hello It appears to be located near the right headlamp

Hello Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.

Where exactly is the horn relay located in the fuze pannel? I have changer the clockspring, checked the horn themselves and still nothing. The cruise control does not work either.Don't know what else to check.

Hello, the horn relay should be located in the battery junction box, under the hood.

One of the databases I looked at showed that picture. If you have an owners manual, it may list the location of fuses and relays? I just wanted to add, two of those terminals at the horn relay, should be hot all the time, just unplug the relay, use a testlite on the terminals. If you use a jumper with inline fuse on the two terminals for the load side of the relay, the horn should honk like crazy.

I have checked the fuses.My horn will not blow.I took the cover off the steering wheel to check the wires,and look for anything out of place.Where is the horn located under the hood?I can not locate the horn.

for your no horn problem i would first check the horn button on the steering wheel, try to manually operate it, DONT USE THE AIR BAG WIRES!

the horn should be located on the front of the grille, sometimes one is hidden by the battery in the front of it.

It seems the horn and windshield washer fluid are connected somehow. When the horn don't work the washer fluid dont work and visa-versa. Also the airbag light on the dash flashes. Sometimes they will work and sometimes they wont.

Suspect and need to check clock spring
located under driver air bag
do an air bag code check to verify

Napa carries the clockspring for around $60.00, just replaced mine. My windsheild was still doesn't work, or my delay wipers. Also replaced the relay for the washer to see if that was the problem. Still doesnt wash, but everything else (cruise, horn, airbag) is working fine.

Mechanic also told me clockspring could be culprit. Ya, I went down to Napa, but the part was out of stock. I wish it was but, I am starting to think that the washer fluid motor is on a separate circuit .

I have a 1993 E150 4.9L and the horn won't work. It has almost 200k. I am thinking about changing the whole steering column, but is there anything else I should check before doing this?

check the power to the horn first. make sure there is power going to the horn. if not, then remove the horn button and make sure the connectors are intact and you have a good ground. let me know

Also won't hurt to check for a horn relay

where would I find the horn relay?

On a 93 Explorer, there are 2 options. Being a 93 Ford, it might be the same. There are no Guarantees.
If the truck has speed control, then there is a horn relay. It looks like it is under the dash near the steering column.
If it dosen't have speed control, it is only the switch in the steering column.
In my explorer book, it goes from fuse #8 to either the relay or switch, and then to the horns.
Try to run a jumper from the hot (+) terminal of the battery to the horn to make sure the horn actually works.

Just realized one more thing.
check the fuse box under the hood. In my explorer, the power for the horn and several other devices routes first through the power distribution box under the hood.

Check the horn fuse?

the horn doesn't work.i don't have a manual and i don't have a ride to get one or money right now.i had checked fuses in the driver side panel and i don't know where else to look to fix the problem.please tell me where to look and what to do incase it's difficult.thank you

The power distribution box I mentioned has both fuses and relays. Look in your owners manual.

check fuse C (20 amp) in the engine compartment fuse box , located left side of engine compartment. if OK check horn relay, same location.. if OK as well then horn switch on steering wheel is probably at fault.

DOES this truck have an air bag. if so DO NOT back prob any wires with power unless you disconnect it. if it does have an air bag it is possible you have a bad clock spring. doese truck have cruse and all that at the steering wheel?

Yes it has cruise and an air bag.

does your cruse work? have you tryed tapping on ht horn with a hammer while someone holds the horn button down. sometimes a little jar will get them going again 8) NOS
