Dealing with bizarre electrical issues in your 2014-2017 Buick Regal? From flickering lights and malfunctioning power windows to strange warning messages on your dash, a failing Body Control Module (BCM) can turn your reliable car into a source of daily frustration. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, the symptoms can be confusing and widespread. Dealerships often quote a small fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a comprehensive cloning service for your 2014-2017 Regal BCM. Instead of selling you a blank module that requires expensive dealer tools, we transfer the critical data from your original BCM directly onto this replacement unit. This means the module arrives at your door ready for installation—no programming, no extra fees, and no hassle. It’s a true plug-and-play fix that restores your vehicle’s functionality precisely as the factory intended.
Common Signs of a Failing Body Control Module
If you’re experiencing any of the following, a faulty BCM is the likely culprit. I’ve seen these countless times in the shop, often misdiagnosed as individual component failures.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Horn honking unexpectedly or failing to work.
- ✔ Vehicle security system acting up, causing no-start conditions.
- ✔ Incorrect readings on the instrument cluster gauges.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
A Technician’s Notebook
I remember a 2016 Regal that came into the bay with a laundry list of complaints from the owner. The radio would shut off randomly, the driver’s side window wouldn’t go down, and the anti-theft light would flash, preventing it from starting about once a week. The owner had already replaced the window switch to no avail. A quick scan showed a network’s worth of communication codes. Instead of chasing ghosts, we went straight to the BCM. A service like this would have been the perfect fix—it directly addresses the root cause without the high cost and scheduling headaches of a dealership visit.
Your Straightforward BCM Installation Guide
Installing your pre-programmed BCM is a manageable job for a DIY enthusiast. Here’s a general guide for your Buick Regal:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Locate the Module: In the 2014-2017 Regal, the BCM is typically located behind the driver’s side of the dashboard, often near the kick panel or steering column.
- Remove the Original: Carefully disconnect the electrical connectors. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the old BCM and remove it from the vehicle.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Power Up: Reconnect the negative battery terminal.
- Final Checks: Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, horn, etc. Address any warning lights as noted in the post-installation section below.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process, some vehicle systems may require a handshake with the new module. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. For procedures specific to your exact model, always refer to a factory service manual or consult with a certified mechanic.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we will contact you with simple instructions to ship your original BCM to us. Once we receive it, our technicians will transfer all the necessary data to the replacement module. We then ship the plug-and-play replacement back to you, typically within 1-2 business days.
Do I need to get this programmed by a dealer after I receive it?
No. The entire point of our service is to eliminate the need for dealer programming. The module you receive will be pre-programmed with your car’s specific data, making it a true plug-and-play installation.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is causing major issues, we can still extract the necessary data. If you suspect your module is completely unresponsive, please contact us before ordering so we can discuss the specifics of your situation.
Is there a core charge for this 2014-2017 Regal BCM?
No, there is no core charge. We only need your original module for the data transfer service. You are welcome to have it shipped back to you with your newly programmed part, or we can recycle it for you.
Will this fix my specific problem?
This service corrects issues directly caused by a faulty BCM. If you’re experiencing the common symptoms listed above, it’s highly likely this is the solution you need. Proper diagnosis is key, so ensure you or your mechanic have confirmed the BCM is the point of failure.
