You can replace the horn button on your 1992 Pontiac Bonneville by removing the center steering will cover. Remove the horn button retaining screws. Remove the horn button wiring harness. Reverse the process to install your new horn button.
Had the same problem. It was my clockspring.
Possible clockspring failure.
Checked the fuses. Tested the horn, direct connection to the battery. Check horn relay. Here is the basic. Between the horn switch and the horn relay is the Clockspring Assembly in the steering wheel. If you ground the red/green wire at the base of the steering column and the horn works, you have either a bad horn switch or Clockspring Assembly.
Defective horn, horn switch, or blown fuse. add to that a possble faulty clockspring in the steering column.
If the vehicle has airbags, you may want to look at the clockspring. It's the connection under the steering wheel that connects airbag, horn, cruise, etc, together.
Normally if the problem is that you can't find the horn button the horn will not work at all. Considering that it only works at times but not always, you've probably got either a bad horn or a bad horn relay. If, however, your airbag light is also on, consider a bad clockspring coil. Also, this is a Dodge, so check for a corroded fusebox. See if wiggling fuses makes the horn work.
check your fuses for power, then check your horn for ground, have someone push on the horn and check for power if still not working check horn pad if worn out in column While the above is good general information, the 2 1994 Ford E-150's that I've had experience with have both experienced "clockspring" failures. All of the electrical devices on the steering wheel go through the clockspring, so a failed clockspring can take out any or all of the horn, cruise control, or airbag. If your clockspring is indeed failed, the fix is to replace it.
it is easier to repair the OEM horn assembly than to "rig" up a button
Checking the fuse is definitely a great idea. Is it just the horn or everything on the steering wheel? If it is everything, it has been my experience that when the horn or any of the options on the steering wheel do not work, it is most likely the clockspring. That is what was wrong with my vehicle. Luckily for my van, the clockspring is a dealership RECALL ITEM. Another indication that it could be the clockspring is the AIRBAG or possibly ABS lights staying on.

Start with the simple stuff. First check the fuse, and you can even pull the cover off of the horn relay in the power distribution center and manually activate the relay to see if the horn works. Most likely cause of this is a faulty clockspring. Usually with a faulty clockspring, the airbag light will be on, the cruise control will not work, and the horn will not work. This is very common on these vans.
