Tired of Unpredictable Electrical Problems in Your Buick Regal?
If your 2014-2017 Buick Regal is suffering from bizarre electrical issues—like flickering dash lights, power windows with a mind of their own, or a security system that randomly prevents your car from starting—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Dealerships will quote you a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a replacement BCM that comes ready for installation through our professional programming service. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result? You receive a module that is 100% plug-and-play. No trips to the dealer, no expensive scan tool subscriptions, and no complex security relearn procedures. It’s the most direct path to getting your car back on the road and functioning correctly.
From the Diagnostic Bay: The Case of the Haunted Regal
A customer brought in a 2015 Regal with a list of complaints that sounded like a ghost was in the machine. The radio would turn on by itself, the driver’s side power lock wouldn’t work, and the instrument cluster would intermittently go dark while driving. There were no engine codes, but the car was full of communication (U-prefix) codes, specifically a U0140 – Lost Communication With Body Control Module. After verifying the BCM had proper power and ground, we knew the module itself was failing internally. Instead of a costly new unit from the dealer, we used this exact programming service. Once the cloned module arrived, it was a 20-minute swap. All the ghost-like issues vanished instantly. This service saved the customer over $500 and a week of downtime.
Common Signs of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your solution:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, etc.).
- ✔ Power windows, door locks, or mirrors behaving unpredictably or not at all.
- ✔ The vehicle’s security system engaging randomly, causing a no-start condition.
- ✔ Horn honking unexpectedly or the alarm going off for no reason.
- ✔ Warning lights for ABS, Airbag, or Traction Control appearing on the dash.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with the BCM (e.g., U0140, U0155).
Your Straightforward BCM Swap Guide
Installing your pre-programmed BCM is a simple process. For the 2014-2017 Regal, the BCM is located behind the driver’s side of the dashboard.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On the Regal, you’ll typically find the BCM to the left of the steering column, often behind the lower dash panel or kick panel.
- Disconnect and Remove: Carefully 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 Replacement: Mount your new, programmed BCM in the same location and securely reconnect all electrical harnesses.
- Power Up: Reconnect the negative battery terminal. Start the vehicle and test all functions—lights, locks, windows, etc.—to confirm the repair.
Important Post-Installation Information
While our programming service makes this a plug-and-play repair, some vehicle systems may require a quick sync-up after the new BCM is installed.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” function. This syncs the airbag system with the new BCM and is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure the brake lights and stability control systems function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
After you purchase, we will provide you with instructions to ship your original BCM to us. We then extract the vehicle-specific data and transfer it to the replacement BCM. We ship the programmed module back to you, ready for installation.
Do I need to do any programming myself?
No. The module you receive from us is fully programmed and ready to be installed. This service eliminates the need for expensive dealer programming.
Where is the BCM located on my 2015 Regal?
On the 2014-2017 Buick Regal, the Body Control Module is typically located on the driver’s side, to the left of the steering column and behind the lower dash panel.
What if my airbag light comes on after I install it?
This is uncommon, but if it happens, it means the airbag system needs to be synchronized with the new BCM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for this part?
No, there is no core charge. We only need your original module for the data transfer service. You can keep your original module after the service is complete.
How long does the entire process take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. Total turnaround time will depend on shipping times to and from our facility.
