Guide to Horn Replacement for the 2011-2017 Buick Regal
If your Buick Regal's horn sounds weak or doesn't work at all, this guide will help you understand the problem and find the right part.
- The 2011-2017 Buick Regal uses a dual-horn system; a weak sound often means one of the two has failed.
- Always check the fuse and listen for the relay's click before assuming the horn itself is broken.
- ACDelco is a reliable aftermarket choice as it is the original GM parts supplier, ensuring proper fit.
- Replacement is a manageable DIY task, but accessing the horns behind the bumper can take some time.
Is Your Buick Regal's Horn Failing?
A problem with your horn can appear in a few different ways. Because these cars have two separate horns (a high note and a low note), a failure in one will often result in a horn that sounds weak, quiet, or just 'off'.
Common Symptoms
- Weak or Quiet Horn: This is the most common sign of a problem. It usually means one of the two horns has failed, leaving the other to work alone.
- Completely Silent Horn: If you press the button and hear nothing, the issue could be a blown fuse, a bad relay, or a problem with the horn switch in the steering wheel.
- Clicking Sound, No Horn: Hearing a click from the fuse box when you press the horn button means the relay is working, but power isn't reaching the horns, or the horns themselves have failed.
- Horn Stays On: In rare cases, a stuck relay or a short circuit can cause the horn to blow continuously. This can be caused by a faulty horn relay or a short in the horn button wiring.
Important First Steps
Before buying a new horn, always check the 15A horn fuse (usually in the under-hood fuse block 🎬 Watch this guide on troubleshooting horn issues for GM vehicles.) and listen for a click from the horn relay when the horn button is pressed. This can save you from buying a part you don't need. A problem with the clock spring behind the steering wheel can also cause the horn to stop working, along with other steering wheel controls.
Choosing an Aftermarket Horn
When replacing a horn on your Regal, you have a choice between original equipment (OEM) and aftermarket parts. For this specific vehicle, ACDelco is a common and reliable choice. ACDelco is the original parts supplier for General Motors, so their parts are engineered to meet factory standards for fit and performance.
While other universal horns might be available, a direct-fit ACDelco replacement ensures the correct electrical connection and mounting bracket, simplifying installation. Some universal parts may require you to cut the factory wiring and splice new connectors, which can be a hassle.
Cost of Replacing a Buick Regal Horn
The cost can vary depending on the part chosen and whether you do the work yourself. The horns are typically located behind the front bumper, which may need to be partially removed for access, increasing labor time.
| Part/Service | Estimated Cost |
|---|---|
| New OEM Horn Assembly | $60 - $90 |
| New Aftermarket Horn (ACDelco) | $73.01 - $73.01 |
| Used OEM Horn | $15 - $35 |
| Shop Labor | $124 - $182 |
Frequently Asked Questions
Where are the horns located on a 2011-2017 Buick Regal?
The horns are typically located in the front of the vehicle, behind the grille or front bumper cover, often on the driver's side. Access may require removing the front wheel and wheel well liner.
Is replacing the horn a difficult DIY job?
It's a feasible DIY job for someone with basic mechanical skills. The difficulty is rated at 2 out of 5. The main challenge is accessing the horns, which may require removing plastic liners or the bumper cover. The horn itself is usually held on by a single bolt.
Do I need to replace both horns at the same time?
It's a good idea. The horns are sold individually (high note and low note), but they have been exposed to the same conditions. If one has failed, the other may not be far behind. Replacing them as a pair ensures a correct, strong sound.
Are there any recalls for the horn on the Buick Regal?
No specific recalls have been issued by the NHTSA for the horn assembly on the 2011-2017 Buick Regal. Likewise, there are no common Technical Service Bulletins (TSBs) related to horn failure.
