Removed the only wire connected to horn it now is only held and connected to frame by a single bolt. Afraid to wire in air horn because horn still sounds even though it has no wire connected to it.


Hi Christian:
Many vehicles have 2 horns so that the sound is more pleasant. If there is no wire connected to a horn, it can not (in my experience) make any sound. May I suggest that you have someone assist you by tapping the horn button while you locate the horn that is sounding.

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.

Horn relay


my guess, its a dead horn? both dead?
no actual question asked????????
the fuse is blow? in fuse box, eng. bay box.?
if no power to horn, (voltmeter)
we check power in and out of relay if there is one.
then at the horn button wire, (air bags can kill any mech. defeat them
first if heck bent to fiddly steering column parts in any why)
all this info is convered in in the FSM, get one. or login to alldata dot come. and read it.
here, ill look at yours. now.... a fast look.
ok 2 horns, hi/lo, and 1 relay in the under hood fuse box.
it should be labeled in the box, HORN
the relay can not work if the fuse is blown
or the horn enable line is dead. button.
the button grounds (0v) the relay via wire color lt.green-blu pin a11 on relay. if the a11 is at 12v the fuse is good.
if you push the horn button this A11 goes from 12v to 0v, and the relay energizes (click) and the horns both blow.
if no power makes it to the horns, the relay is bad no 12v
if by chance the relay output to horns go to 12v, then the horns are both dead.

On my 1995 crown vic. one day horn blew on its own for about an hour. i looked and fuse was blown now when i put new fuse in and hit horn, horn sounds for second and fuse blows. everytime i put fuse i


Sounds l;ike the horn itself has a short. Try another from a salvage yard. If fuse blows again, it's likely a wire to horn that lost insulation and touching metal.
Good luck.

I have a 1995 Chevy S 10 and the horn does not work. I think my problem is under the dash. Are there any switches,relays, or breakers I need to be looking\r\nfor? I have traced from horn to fuse panel and...


The horn relay is in the fuse/relay box under the hood. so the fuse is HOT on both sides? you should hear the horn relay click when pressing on the horn switch. there may be other relays in that fuse box to swap with and see if the horns work, if the relay clicks, its "usually" good, but the contacts may be bad. if the relay clicks, check for power at the horn. DARK GREEN wire, if it has power , then check the black wire, thats the ground. If it has power and ground, but does not work, the horn is bad.

FIRST I WOULD CHECK THE HORN FUSE OR RELAY ...CHECK YOUR OWNERS MANUEL TO SEE FOR LOCATION PROBABLY UNDER HOOD IN A RELAY STATION BOX.IF THOSE ARE GOOD..THEN POSSIBLE BAD HORN ITSELF OR BAD CONTACT BEHIND THE DRIVER AIRBAG,STEERING WHEEL.

My horn is not working at all on my 2005 prius??? What to do??


There is a 10 amp horn fuse either in your cabin fuse box or the engine compartment fuse box. If it is not the fuse, you will need to troubleshoot to find the cause. First, find the horn relay (usually in the engine compartment relay box) and pull it out. Have someone hold the horn button down while you push the relay back into it's socket. The relay should click as you push it in. If it clicks, your problem is probably in the wiring to the horns. You'll have to trace the wires from the horns to the relay box to see if the connector went bad or what happened. If the relay doesn't click, you can try replacing the relay, but the problem may also be with the horn button. To troubleshoot the button, you need a 12 volt test light. You can get one for a few bucks at a parts store or WALMART auto tools isle.
Use the test light to interrogate the relay socket. Remove the relay from it's socket. connect the clip of your test light to the positive side of your battery and then probe all of the relay socket terminals while someone holds the horn button down. One of the terminals should turn the light on bright. Some of the terminals may light it dimly, but at most one will make it bright. If none makes it bright, your horn button is not working or the wire from the horn button to the relay box is cut. If you have questions, please let me know. If you want to understand the relay, see my post at http://www.fixya.com/cars/r6022358-relay_check

Pontiac Grand Prix horn does not work. What is the best way to troubleshoot?


First, always check fuse.
2. If good, use test light at horn with button pressed to see if horn is getting voltage. If yes, replace horn.
3. If no, trace your way back--find horn relay in engine compartment fusebox and listen to see if it clicks when button is pushed. If yes, the wire from the relay to the horn is bad.
4. If no, remove the relay and test the socket for command signal from the horn button. See my tip at http://www.fixya.com/cars/r6022358-relay_check for how to check relay socket. If command signal is present, replace relay.
5. If not, the problem is with the wiring from the horn button to the relay.

Please let me know if you have questions

Purchased 1996 Ford Crown Victoria. On driving it home the cruise control went out. Tried to reset and won't work, as well as the horn. What is the problem?


The horn relay is located toward the front of the engine. It is located just behind the radiator overflow reservoir and attached to the inner fender next to two other relays. It is the only one without a plastic cover over the top of it. FYI, our Crown Vic horn didn't blow, and the cruise didn't work. I changed the relay and still no horn. I decided to check the horns themselves. Found wires disconnected from terminals. Touched wire to horn terminal and horn blew incessantly. (previous owner had disconnected horn rather than diagnose why) Pulled the horn "button" from steering wheel and disconnected the wire leads and horn quit. Disassembled the "button" assembly. Foam had degraded over time between the contacts. (Ford has discontinued this part). Cleaned and replaced foam with Scotch foam mounting squares with holes punched out over contacts (2 layers thick). Re-assembled and viola! Horn and cruise control both work! Relay was bad as was horn button.
