Question about 1997 Buick LeSabre
I have the same problem with the same car, was told by two differenr buick dealers that this was a pretty common problem with year buick, both places told me that the sensor under the horn pad needs to be changed, which involves removal of air bag.
I would suggest taking to a dealer and having it fixed. that way everything works properly. Hope this helps.

Hey there Mudman,
The fuse may provide power to other systems. I'd be reluctant to pull it. And you probably don't want to pull the steering wheel apart.
The easiest, fastest solution is pull a wire from the horn itself.
Open the hood and find the horn. Normal location is up front near the grill. Once located, the wire coming from it should have a connector that you can pull off.
Some vehicles have more than one horn, so try it out and make sure this 'silencer worked.
That should do it.
Remember: Good things come to those who rate!

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.
