    my horn went off too at 3 am . I disconnected the horn but I sure miss it. The post saying the pad gets warped by the sun makes total sense. Sounds like the only fix is to get a new pad

The horn pad is warped from heat (from the sun), this causes the horn contacts to touch, very common issue on the Protege.

I experienced the same thing with my 1993 Protege. I found some thin foam and created a template to match the deteriorated foam on the steering cover. I replaced the old with the new and it's been working ever since. Thanks!

  • Take off the horn cover, disconnet the horn and bend out that copper metal plate by pushing it in. Connect horn and try it out. I had the same exact problem

1997 Honda CRV horn starts blaring when driving down the road.


Most likely wire inside steering column has rubbed a bare spot and is shorting. Short term fix is disconnect horns. Might check horn relay first by tapping with broom handle of such.

Horn does not operate


I would check for the following:
1. Fuse
2. Relay
3. Wiring
4. Horn itself (disconnect it from the car, use a wire to connect to horn and tap it directly to the battery, if it horns then it is ok, if not probably need a replacement.
5. Push button on the steering wheel
6. Rotor contact on the steering wheel

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.

Cruise control not functioning


You have a defective clock spring ribbon rotating contact drum under the steering wheel, contact a local repair shop for more details on this part and how to replace it, since the airbag is involved in this repair it is best left to the dealer or a shop you trust.

I have a 2004 chevby impalla. The car was parked in my garage last night and the horn just started blaring. I tried the alarm button on key it did not stop.I started the car the horn Left blaring. I...


I wonder,, with colder tempratures this time of year, If somehow a connection in the horn pad was shorting out.due to expansion or contraction of a component inside the steering wheel. Try tapping on the top of the air bag on the steering wheel and horn buttons ..this may work ..note this is a guess and I hope this does it the only reason I mentioned it Is because I have seen this two other times...Good luck.

Horn stops work periodically


hi , if like a similar problem i had years ago , the problem is either a bad connection on the steering wheel or an earth fault on the horn its self ? the car i had the fault on was a mk1 golf and under the steering wheel was a copper strip round the neck of the wheel where its connected to steering rod.....the connection (similar to a motor armature brush) was not making a good connection, i cleaned them with wire wool and hey presto. hope this helps??
