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.
2. 2.
There are two plastic twist locks (turn ¼ left) and one small wing nut holding
the cover on. When the cover is off I see two black fuse covers side by side
and below them are several relays. Some are gray and some are black.
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.

This is a fairly common problem, Gm has actually issued a service bulletin regarding this repair. The problem probably originates from one of your wheel speed sensors that is mounted inside one of your front wheel bearings. To be sure, you need to have the car scanned to find out which one and then you have to replace the whole bearing assembly because the sensor is integral to the bearing. The bearing is not hard to do but you will need some professional tools if you want to do it yourself. At a shop it should cost between 3 and 400 dollars complete.

Take horn relay out and look for corrosion on prongs.
