SOURCE: 1995 Buick LeSabre - horn blows
My horn would honk without any assistance from me. The
reason was because the plastic cover for the air bag and horn switches had
shrunk so tight that it pressed on the horn switches. If your problem is
intermittent then cold temperature would also cause the cover to shrink. This
is how I solved the problem on my 1995 Buick LeSabre:
Disconnect the negative battery cable.
3. My horn relay was the second from the left as I faced the rear of my car. It was gray. Some may be black.
4. A small green retainer tab had to be pushed out before I could pull the relay out. On the back of the relay were two orange wires that supply 12V. One green wire that goes to the horns and one black wire for ground that goes to the horn switch under the air bag.
5. I cut the black wire and wired in a spst push button switch that I connected to ground.
6. I mounted the push button switch near the driver’s door on a flat part of the dash. I used very strong double sided tape to secure the button switch to the dash.
My horns now are activated when I push my new horn switch button. My problem solved.
Someone recommended removing the air bag/horn switch unit from the steering wheel and relieving the tightness of the plastic cover. There are probably more than one way to this.

your horn relay is located under the hood in the black box that also houses the fuses and relays for your whole car .. under the lid for this black box is the location for all the relays and fuses check it out and see if it has your horn relay in there thanks and holler if you need more. Jerry

Your vehicle's fuel pump relay is located on the relay center, behind the glove box, 2nd column of relays, 2nd one from the top.

The coded key probably needs to relearn. Turn ignition to crank and release. Let sit in on position (engine off of coarse) for a full 10 min. turn off for 30 sec. and repeat 3 times engine should start. This procedure should take 30 min. so a booster is needed to maintain a full 12 volts. Do not attempt w/out a charger connected;
