Restore Your Vehicle’s Electrical System and Drive with Confidence
Are you battling a storm of bizarre electrical problems in your Buick Regal or other GM vehicle? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or warning lights that won’t go away are classic signs of a failing Body Control Module (BCM). As the central nervous system for your car’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. This isn’t just an annoyance; it can affect vehicle security and safety systems.
We offer a straightforward, reliable solution. This is a replacement BCM that comes fully programmed with your vehicle’s specific data. By cloning the information from your original module, we provide a part that is truly plug-and-play. This process bypasses the need for expensive dealership visits for programming, saving you significant time and money. Simply send us your original BCM, and we’ll handle the complex data transfer, shipping you back a fully functional module ready for installation.
A Technician’s Notebook: The Case of the Phantom Battery Drain
A customer brought in a 2015 Buick LaCrosse with a persistent battery drain that two other shops couldn’t solve. The battery was new, the alternator tested fine, but every morning the car was dead. After hours of parasitic draw testing, I noticed the interior dome light would faintly glow for hours after the car was locked. It wasn’t enough to be obvious, but it was killing the battery. The issue wasn’t the light itself, but the BCM failing to send the proper ‘sleep’ command to the lighting circuit. We swapped in a cloned BCM, and the problem vanished instantly. It’s a perfect example of how a failing 2014-2017 Regal Body Control Module can cause symptoms that seem unrelated at first glance.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. This module can trigger a variety of Diagnostic Trouble Codes (DTCs), often starting with ‘U’ for communication errors (e.g., U0140 – Lost Communication With Body Control Module).
- âś” Erratic or non-functional power windows, door locks, or mirrors.
- âś” Interior or exterior lights staying on or not working at all.
- âś” The security system or keyless entry malfunctioning.
- âś” Instrument cluster gauges behaving erratically or going dark.
- âś” Unexplained warning lights on the dashboard, such as for the airbag or traction control.
- âś” The vehicle failing to start despite a good battery and starter.
A Straightforward Guide to Installation
Our cloning service makes the physical replacement simple. Once you receive your programmed module, follow these general steps. The BCM in the 2014-2017 Regal is typically located behind the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the Regal, this is usually behind the lower dash panel on the driver’s side (LH dash). For other models, refer to the fitment list for its location. You may need to remove a trim panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. 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 securely re-attach the electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—lights, locks, windows, etc.—to confirm the repair.
Important Post-Installation Notes
Because our service clones your original data, most vehicles will not require any additional steps. However, in some cases, specific systems may need to be re-synced:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure the brake lights and traction control system function correctly. This can also be performed with a compatible diagnostic tool.
- No Core Charge: You are not required to return your old BCM to us after the service. There is no core charge.
Disclaimer: Vehicle systems vary. For procedures specific to your exact model, we always recommend consulting a factory service manual or a certified automotive technician.

Frequently Asked Questions About Our BCM Service
Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we will contact you with detailed instructions and a shipping address. You securely package and ship your original BCM to us. Once we receive it, our technicians will extract the data and transfer it to the replacement module. We then ship the ready-to-install BCM back to you, typically within 1-2 business days.
Will this fix my specific problem?
This 2014-2017 Regal Body Control Module is designed to correct issues directly caused by a failing BCM, such as problems with lights, locks, windows, and security systems. While it solves the most common electrical faults, proper vehicle diagnosis is recommended to ensure the BCM is the source of your issue.
Do I need any special tools for installation?
For the physical installation, you’ll only need basic hand tools to access the module (e.g., a screwdriver or socket set). In rare cases, as noted in our post-installation section, a professional scan tool might be needed to clear an airbag light or perform a relearn procedure.
Is this a guaranteed fit for my vehicle?
Yes, if your vehicle is on our compatibility list and your original module matches one of the listed part numbers, this is a guaranteed fit. Our cloning process ensures it works with your car’s specific options and VIN.
What is the benefit of cloning my old module versus buying one from a dealer?
Cloning provides a true plug-and-play part. A new BCM from a dealer is a blank slate and requires expensive, vehicle-specific programming using their proprietary software. Our service embeds your car’s unique identity—like key fob data and option configurations—into the replacement module, saving you hundreds of dollars and a trip to the dealership.
