Restore Your Regal’s Electrical System with a Hassle-Free Solution
Are you chasing down frustrating electrical gremlins in your 2014-2017 Buick Regal? Intermittent power windows, flickering lights, or a key fob that works one minute and not the next are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s comfort and convenience features. When it starts to fail, it can make your vehicle feel unreliable and unpredictable. Dealerships often charge a small fortune for a new module plus expensive programming fees. We offer a smarter, more affordable path back to reliability.
This is a replacement BCM that comes fully programmed for your specific vehicle. Our service is simple: you send us your original BCM, and we expertly transfer all its critical data—including your VIN, key programming, and other vehicle-specific settings—to this replacement unit. The result is a true plug-and-play module that eliminates the need for a trip to the dealer. You get a reliable part that works right out of the box, restoring full functionality to your vehicle’s body electronics.
A Technician’s Notebook: The Case of the Erratic Regal
A customer brought in a 2015 Regal with a laundry list of bizarre symptoms. The radio would randomly shut off, the driver’s side window wouldn’t go down, and the remote start was completely dead. They had already replaced the battery and checked fuses with no luck. A quick scan with my diagnostic tool showed multiple ‘Lost Communication with BCM’ codes (U-codes). Instead of a specific component failure, this pointed to the network hub itself—the BCM. We confirmed power and ground to the module were good, isolating the BCM as the culprit. By providing a programmed 2014-2017 Regal Body Control Module using their original’s data, we had the car back to 100% functionality in a day, saving the customer over $500 compared to the dealer quote.
Is Your Regal Showing These Signs of BCM Failure?
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior dome lights or exterior lamps staying on or not turning on.
- ✔ Key fob or remote entry system not working correctly.
- ✔ The security or anti-theft system acting up, sometimes preventing the car from starting.
- ✔ A dashboard lit up with various warning lights without a clear cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.

Your Straightforward Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: In the 2014-2017 Buick Regal, the Body Control Module is typically located on the left-hand (driver’s) side of the dash, often behind the lower dash panel or kick panel.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and reconnect all electrical connectors securely.
- ✔ Reconnect Battery: Re-install any trim panels you removed and reconnect the negative battery terminal.
- ✔ Test Functionality: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Notes
While our programming makes this a plug-and-play repair, some GM vehicles may require a final sync procedure. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
- No Core Charge: You can keep your old module, as there is no core charge or need to return it after the service.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician for your specific model.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages the non-engine related electronic systems in your car. This includes power windows, power locks, the alarm system, interior and exterior lighting, key fob functions, and even the windshield wipers. When it fails, you’ll notice problems with these features.
Why is cloning my original BCM better than just buying a used one?
A standard used BCM from a junkyard will have the VIN and security information from the donor car. Installing it will cause a mismatch, likely preventing your car from starting and disabling many features. Our cloning service transfers your car’s unique data, making the replacement module a perfect match and ensuring a simple, plug-and-play installation.
Is this really a plug-and-play solution?
Yes. Because we clone the data from your original module, this replacement part requires no additional programming to start the car and operate basic functions. In some rare cases, as noted in the description, a simple relearn procedure for the airbag or brake pedal sensor may be needed, which can be done with a high-end scan tool.
How long does the programming service take?
Once we receive your original BCM, our technicians typically complete the programming service within one to two business days. We then ship the programmed replacement module back to you immediately. You will receive tracking information as soon as it ships.
What do I do if my airbag light is on after installation?
If the airbag light comes on, it means the BCM and the SDM (airbag module) need to be re-synced. This does not indicate a problem with the part. A qualified mechanic will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional diagnostic tool to turn off the light.
