What relay is the horn on a 1995 buick park avenue?

There isn't a single, dedicated "horn relay" in the way some cars have a clearly labeled component. The 1995 Buick Park Avenue's horn circuit is usually controlled through the Body Control Module (BCM) or a similar integrated system. The BCM acts as a relay itself, sending power to the horn based on the steering wheel's horn button input.

Therefore, you won't find a separate relay to replace. Troubleshooting a non-working horn would involve:

* Checking the fuse: Start here! The horn has a fuse in the fuse box (typically under the hood or in the dash). Check the owner's manual for the correct fuse.

* Inspecting the horn button: Make sure the button in your steering wheel is working properly. Sometimes they wear out or become disconnected.

* Testing the horn directly (Caution!): With the ignition OFF, you can temporarily connect a wire directly to the horn terminal, then use another wire (with an alligator clip) to briefly connect the second horn terminal to a 12V ground. If the horn works, it's likely a wiring or BCM issue. Be extremely cautious doing this to avoid a short circuit.

* Diagnosing the BCM: If all else fails, the problem likely lies in the BCM. This usually requires professional diagnostics with a scan tool to check for any stored codes related to the horn circuit.

In short, while there might be a relay *somewhere* within the BCM or other larger electronic control unit, it's not a replaceable part in the same way as a simple relay in older cars. You'll need to troubleshoot the electrical circuit to determine the real cause of your horn not working.
