Tired of Unpredictable Electrical Problems in Your GM Vehicle?
If your 2014-2017 Buick Regal is acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or a frustrating no-start condition—a failing Body Control Module (BCM) is the likely culprit. As the central nervous system for your car’s electronics, the BCM’s health is critical. When it fails, it can cause a cascade of confusing and inconvenient issues. Dealerships often quote astronomical prices for a replacement and programming, leaving you with a huge bill and vehicle downtime.
We offer a smarter, more affordable solution. This is a complete, plug-and-play 2014-2017 Regal Body Control Module that is professionally programmed using the data from your original unit. Simply send us your factory BCM, and our expert technicians will transfer all the critical vehicle-specific information to this replacement module. We then ship it back to you, ready for installation without any need for expensive dealer tools or additional programming. It’s the most reliable and cost-effective way to get your car back to 100% functionality.
A Technician’s Notebook
I recently had a 2015 Buick Regal in the bay that was a real head-scratcher. The customer reported intermittent issues: the radio would cut out, the driver’s side window wouldn’t respond, and occasionally the car wouldn’t start, but there was no check engine light. We checked the battery and all major ground points—they were perfect. After connecting a scope, we saw erratic data signals on the low-speed CAN bus network. These ghost-like problems, which don’t always set a clear trouble code, are classic signs of an internally failing BCM. A simple component swap with a programmed module like this one resolved all issues instantly, saving the customer over $700 compared to the local dealer’s quote.
Common Signs of a Failing BCM
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, your BCM may need replacement:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system light stays on, preventing the car from starting.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers or horn activating on their own or not working at all.
- ✔ Key fob recognition problems.
Your Straightforward BCM Installation Guide
Installing your newly programmed BCM is a manageable task. On the 2014-2017 Regal, the BCM is typically located behind the left-hand side of the dashboard. Always consult a service manual for your specific vehicle’s diagram.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to ensure all systems are powered down.
- Locate the BCM: Access the BCM, which is usually found in the driver’s side footwell area, often behind the kick panel or part of the dash.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount the replacement 2014-2017 Regal Body Control Module in the exact same position as the old one. Securely reconnect all electrical harnesses.
- Reconnect Power: Reattach the negative battery terminal.
- Test All Functions: Start the car and systematically test all body functions: lights, windows, locks, wipers, radio, and horn to confirm the repair.
Post-Installation Procedures
Because this module is cloned from your original, most functions will work immediately. However, in some cases, certain security or safety systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential requirements:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does this cloning service work?
After you purchase, we will provide instructions for you to ship your original BCM to us. Our technicians will then extract the vehicle-specific data and flash it onto the replacement module. We then ship the programmed module back to you, ready for installation.
Will I need to program this module?
No. Our service handles all the programming. The BCM you receive will be plug-and-play, saving you a trip to the dealership and expensive programming fees.
Is this a guaranteed fix for my car’s electrical problems?
This module will fix issues directly caused by a faulty BCM. If you’re experiencing symptoms like erratic lights, window/lock failure, or communication error codes (like U0140), a failing BCM is the most common cause.
What if my airbag light comes on after I install it?
This is a possibility. It means the airbag system needs to be synced with the new BCM. A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a shop with a professional-grade diagnostic tool to turn the light off.
Is there a core charge?
No, there is no core charge for this service. The process is based on cloning the data from your original module to the replacement unit we provide.
