SOURCE: Where is the horn relay on a 1991 Mitsubishi Montero

Although the Haynes repair manual did not have an electrical diagram for the horn circuit, I suddenly remembered I had an old CD-ROM based Auto Repair program from Popular Mechanics that has an extensive selection of diagrams. It did have a diagram for the horn circuit which showed that there was no horn relay in the circuit. So I started by taking apart the horn button on the steering wheel. The horn button is a switch consisting of two metal discs approximately two inches in diameter which are separated by a thin layer of foam which is supposed to keep the two discs separated. The metal discs have dimples that should be kept apart by the resiliency of the foam but when the foam is compacted, the dimples come together to complete the circuit. However, the foam had deteriorated to almost nothing and was allowing the two discs to be in constant contact. I solved the problem using picture hanging tape. This is a double-sided adhesive tape that is about 1/16 inch thick and comes in a roll and can be found probably anywhere hardware is sold. I cut the tape into small squares and stuck them to strategic points on the flat parts of one of the discs so that they would keep the discs apart with approximately the same resiliency as the foam. When external pressure is applied to the outer disc, the dimples come together just like before to complete the circuit and the horn works perfectly.
One thing I would like to point out is that when I initially took the horn apart, I started by removing the outer soft rubber cover from the horn pad to expose the horn button. It came off easily, but when it came time to put it back together, I could not get the cover back on. Then I discovered that there are three phillips head screws on the back side of the steering wheel that hold the horn button assembly in place. So to save time and frustration, I would recommend that step one be to remove those screws first.

SOURCE: horn won't stop blowing

If you can locate and pull relay, do that, if not, pull wires off at horn if you can, otherwise pull fuse. If you have other relays same in area of horn relay (same number on relay) try one of them in that horn spot to see if maybe it's just a stuck relay.If you pull fuse for horn, you may find out something else on same fuse, so make sure you check everything else is working.

The horn will not stop blowing hyundai sonata 2004


This is usually caused by a short in the steering column or clockspring but can be caused by a broken relay. Remove the horn relay, disconnect the horn, connect the battery, and listen for a click when you reinsert the relay. If it clicks, the relay is working properly and the problem is in the steering column.

Horn blows by itself


I verify its not a stuck relay...

I disconnect connector under dash and horn stops...


I then suspect its the Horn contacts or a worn grounded wire in air bag/horn switch assembly in steering wheel.




The decorative Vinyl cover shrinks with age...presses on horn contacts against air bag.

I Disconnect Air bag connector (identified as Yellow wire and Connector) usually under dash.

WARNING: ( I Do not - I DO NoT probe the yellow harness/connector with a meter or test light. A test light WILL Detonate my air bag, and impale the bracket in a nearby object/person - me.)

I Removed screws (2) behind steering wheel - which allow air bag horn assembly to be removed.


I Disconnect Air bag connector in this location as well (identified as Yellow wire and Connector) and then;




The red (color varies) and black Horn wires will be plugged into ribbon connectors usually (2) two that feed/connect to contacts for horn function on face of air bag.

I pause here and verify horn will stop blowing when I disconnect the wires going to horn contacts. So I get horn blowing again...

Check horn: To verify this is the cause; I reconnect (whatever fuse/relay/ connector (Not the airbag connector) I disconnected so they will stop blowing) and get horn/s so they are blowing again...

Then I disconnect the ribbon connectors to verify blowing stops.

Note: The experience I had with horn on

Buick Park Ave was at night when temperature cools after hot day, the vinyl cover shrank and horn blows... pressing on horn area of steering wheel firmly would stop horn briefly - then continue.

Note: I will need a rivet tool and rivets... to reassemble.

WARNING: I Do not drill into airbag explosive container. If I do not know how to carefully drill off correct rivet heads and remove vinyl decorative cover from air bag/horn... I STOP and go to the junkyard or ebay and purchase/replace the airbag/horn assembly.

I continued by drilling out rivets (the rivets holding vinyl cover) by using a drill bit as large (or smaller) as the head of rivet and drill gently to release head from rivet body/shank.



I mark all pieces with a magic marker to verify I reassemble right side up (all metal brackets and trim plates and cover).



I Remove vinyl cover exposing horn contact pads which were sandwiched between cover and air bag container.

I used a razor blade to remove vinyl honeycomb material from area of vinyl cover - that when pressed - would activate horn/contacts.

Only a 1/16 of an inch or less needs to be removed.

(I Bend cover inside out and shave material off of area slowly. Care not to cut myself.)

I Reassemble in reverse order with rivets.

Check horn: ...function at this point... by plugging in horn connectors and assure horn contacts work properly as expected.

My horn sounds off and won't stop 'til I disconnect battery cable. Why?


sounds like there's a short in your wiring in the steering column, A lot of times with a tilt wheel a wire get loose or gets a short in it. the steering wheel may have to come off to fix the problem but make sure to disconnect the airbag first, I'm not sure what vehicle you have so I don't know where to tell you to look for the connection, may be best to take to a dealership if possible. Hope this helps.

2004 Toyota Sienna horn blows and lights flash for no reason, then stop for a few minutes and repeat again.


If a critical supply is removed, (relay that feeds?) then the alarm will think the car has been tampered with.

For 2004 ford truck f150 extended cab, I found the horn fuse, where is the horn relay?


disconnect the horn or horns, operate the horn and see if the fuse still blows. if the fuse still blows then there is most likely a short in the wiring. relays rarely cause shorts. if the fuse doesnt blow with the horn disconnected, reconnect the horn and operate the horn again, if the fuse blows you have a shorted horn.

My horn will not stop honking.


Fuse # 15 control power to the horn relay, remove the fuse and see if it stops blowing, that is one test, secondly remove the relay to see if this disable it. You could also have a horn button that is stuck in the engage position.

2006 grand prix horn fuse keeps blowing. what should i look for


horn may be shorted internally. Try pulling the connector off the horn, put in a fresh fuse, see if it blows.

If it still blows, you have a short in the wiring or the relay. If there is no obvious short in the wiring, change the relay.

If the fuse doesn't blow with the horn disconnected, replace the horn.

Horn? no sound


First check the fuse. Check to see if you have power at the horn when you try to blow it. You should have 12 volts when the someone presses the steering wheel. If the fuse is good and you have power remove the horn and test it again by grounding it to the vehicle and then applying 12 volts to the connection. If the horn does not blow replace it.

The horn on my 2004 Grand Am gradually stopped working. (When using the remote to lock the doors, sometimes the horn would barely bleat, at other times it sounded fine.) Fuses and connections seem ok....


no, sounds like its time for new horns, have someone push horn button while you check for power at the horn, if theres power then replace the horns,sounds like bad horns to me,good luck.

Horn


my horn did the same thing - we disconnected the horn (which in an 02' is behind the passenger side headlight) I'm sure it's wearing out and we need to replace it.
