I have a 1995 buick leasbre and my car horn goes off by itself how do I disconnect my car horn?

Check for a relay under the hood in a relay compartment . could be the cause of fault.

I believe it is the fourth relay from the left passenger side in the engine compartment against the firewall. I am assuming your horn intermittently goes off by itself. It's a interior heat related issue. The horn pad cover on the steering wheel has a membrane layer. It's basically a switch that has one wire that goes to the horn relay to activate the horn. The Buick GM logo embossed on this plastic cover is where I found it most sensitive to any light touch. Unhook the battery. If you carefully cut the right edge of the the steering wheel horn pad and carefully pry it out a little, it will fix this issue and still be able to use the horn. It's another GM defect. I hope this helps! Let me know.

The easy way is to locate the horn under the hood of your car and reconnect the wires to the horn

Have you checked all your wiring to the horn and made sure there is no shorts in it ????

the contact in the steering wheel is shorting out, all you can do is replace it,, however,, any time your messing with the steering wheel or anything associated with it, you must use extreme care,, prior to doing anything, disconnect the Neg battery terminal,, then the positive one, and wait 10 minutes, this will allow the air bag system time to discharge, the last thing you need is the air bag going off, once this has been done, behind the wheel, there will be recessed screws that hold on the face of the steering wheel cover,, remove those, and pull off the cover gently,, your going to have a single wire, ( there are others, But your concerned with the single one, that's for the horn) make sure that is secure . if it seems that wire hasn't worked loose then your problem is going to be in the contacts on the horn buttons, some of these are actually molded into the cover and can't be replaced,, which would mean you have to replace the cover itself,,

There will be a horn relay that is stuck replace it,it is in with the fuse/relays

The contact point is in the steering wheel. You may need to remove airbag by disconnecting battery and removing the screws on backside of the steering wheel then a wire. The horn will be underneath the airbag. The horn contact will be a plastic insulator and a spring. Check here to see for broken parts. Good luck.

horn switch defective. Replace it or adjust it to fix your problem.

YOU have a bad horn contact pad.

Good Day,

Something else you may want to check is the wire attached to the horn. You can check this by removing the horn assembly from the steering wheel. There is a wire that connects to the back of the horn pad, over time road vibration can knock this loose as it is held on by a small clip. You can also check the connection on the horn itself under the hood. Here's a pic of what the horn phyiscally looks like.


Hope this helps
