That depends entirely on what's wrong with the horn.
It could be a problem with the horn relay, in which case you simply replace the relay. (Under the hood, in the fuse/relay box next to the battery)
It could be a problem with the horn itself, in which case you simply replace the horn.
It could be a problem with the horn switch, which is a part of the steering wheel. If that's the case you'll need to replace the steering wheel or horn switch.
It could be a problem with the horn wiring, in which case you'll need to track down the specific problem and repair it.
Good luck.
The horn is right in the middle of the steering wheel on a 2002 L100, and I assume so on all L-Series vehicles.
The horn relay is under the airbag in the steering wheel. Best to let Saturn dealer fix it.
1. Remove the driver's side headlight. 2. Unbolt the horn and bracket from car. 3. Get replacement 3-wire horn. (available from Saturn for ~$70) 4. Install new horn and bracket on car. 5. Intall headlight.

Drive to your local parts store or GM dealer and they can tell you what it is.
GM vehicles do not have a fuel shut off/inertia switch
One side of the horn probably has direct power, and the other side is the switching side. So when the horn button is pushed, the relay connects the horn to ground. Check the relay it is most likely bad.
This car holds 5 quarts of 5w-30 oil.
To fix the horn on a 1988 Camaro, check the horn fuse first. Then check the horn relay, wiring, horn, and switch to find the problem.
This is rather simple actually. You light the entire car on fire! Hope this helps.
