Is Your Buick Regal Suffering from Baffling Electrical Issues?
Are you dealing with flickering lights, power windows that have a mind of their own, or a security system that randomly activates? These aren’t just minor annoyances; they are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s electronic accessories, managing everything from your interior lights and power locks to your climate control and anti-theft system. When it starts to fail, it can create a cascade of frustrating and unpredictable problems that can be difficult to diagnose.
The Simple, Cost-Effective Solution: A Pre-Programmed BCM
Replacing a BCM traditionally means a costly trip to the dealership for the part, installation, and expensive programming. Our service eliminates that hassle. We provide a replacement 2014-2017 Regal Body Control Module that is precisely programmed with the data from your vehicle’s original unit. This cloning process ensures that the replacement module is a perfect match for your car’s specific configuration, including its VIN and optional features. The result is a true plug-and-play solution that gets you back on the road without the dealership’s high costs and long wait times.
From the Diagnostic Bay
We had a 2015 LaCrosse come in with the strangest symptoms. The radio would turn on and off, the dome light would flicker while driving, and the key fob worked intermittently. The owner had already replaced the battery and checked the alternator, but the gremlins persisted. A quick scan showed multiple communication errors pointing towards the BCM. Instead of a complex rewiring job, we performed a BCM clone. Once the programmed replacement was installed, every single issue vanished. It’s a powerful reminder that what seems like multiple separate problems can often be traced back to this single, critical component.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from the dashboard lights, headlights, or interior lighting.
- ✔ Malfunctioning climate control system.
- ✔ The security system or alarm activating for no reason.
- ✔ Key fob not working or responding inconsistently.
- ✔ “Service Theft System” or other warning messages on the dash.
- ✔ Battery drain issues caused by the BCM not properly shutting down accessories.

Post-Installation Procedures
In most cases, this is a direct plug-and-play installation. However, for some vehicles, minor recalibrations may be needed:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for monitoring and controlling various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for your car’s body electronics.
Why do I need to send you my original BCM?
Your original BCM contains vehicle-specific data, including the VIN and settings for your car’s options. We transfer this critical data to the replacement module, making it a true plug-and-play part and saving you from expensive dealership programming.
Is this part difficult to install?
The physical installation is typically straightforward. The BCM is often located in the driver’s or passenger’s side kick panel or behind the dash. Once you access it, it’s a matter of disconnecting the battery and swapping the electrical connectors.
Will I need any special tools for installation?
Basic hand tools are usually sufficient for the physical replacement. However, as noted in the post-installation procedures, a professional diagnostic scan tool may be required for certain relearn or sync procedures, like the airbag system sync, if a warning light appears.
What is the turnaround time for the programming service?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. You will receive tracking information as soon as it ships.
