Restore Your Buick Regal’s Electrical System with a Hassle-Free Solution
Are you dealing with bizarre electrical issues in your Buick Regal? Flickering lights, malfunctioning power windows, a horn that won’t stop, or even a no-start condition can all point to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create frustrating and unpredictable problems. Dealerships often charge a small fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable path forward.
This is a fully tested, replacement Body Control Module for your 2014-2017 Regal. The key to our service is that we transfer the critical data from your original BCM directly onto this replacement unit. This cloning process makes the module a true plug-and-play component for your specific vehicle, eliminating the need for expensive dealership programming. You get a reliable fix that restores your car’s original functionality without the extra cost and headache.
Diagnosing the Problem: Common Signs of BCM Failure
- ✔ Unpredictable instrument cluster behavior, including gauges dropping to zero.
- ✔ Power windows, door locks, or interior lights working intermittently or not at all.
- ✔ The security system acting up, causing no-start or crank-no-start conditions.
- ✔ Headlights, taillights, or turn signals malfunctioning.
- ✔ False warning lights appearing on the dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
From the Diagnostic Bay: The Case of the Haunted Regal
A customer brought in a 2015 Regal with a list of symptoms that sounded like the car was possessed. The radio would change stations on its own, the dome light would flicker at highway speeds, and twice the alarm went off in their garage for no reason. We couldn’t replicate the issues consistently. After checking grounds and wiring harnesses, we suspected the BCM. Instead of a costly new module from the dealer, we used a cloned unit. The process was simple: we sent in the customer’s original BCM, got the programmed replacement back, and installed it. The ‘haunting’ stopped immediately. This is a classic example of how a failing 2014-2017 Regal BCM can cause chaos, and how our service provides a direct, effective fix.

- ✔ Cloning Process: Upon receipt, our technicians will professionally transfer all necessary vehicle data from your old module to the replacement unit.
- ✔ Return Shipping: We ship your newly programmed, ready-to-install BCM back to you, typically within 24-48 hours of receiving your original. Tracking information will be provided.
- ✔ Installation: Disconnect the negative battery terminal. Install the programmed BCM, reconnect all connectors, and then reconnect the battery.
- ✔ Final Checks: Start the vehicle and verify that all body functions (lights, windows, locks) are operating correctly.
Important Post-Installation Notes
While our programming makes this a plug-and-play installation, some GM vehicles may require additional sync procedures depending on their specific configuration. These are not always necessary but are important to be aware of:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade diagnostic tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure correct brake light operation and traction control performance.
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 the programming service work?
After you place your order, we will provide instructions to mail your original BCM to us. We then copy the vehicle-specific data to the replacement BCM and mail it back to you. This makes it plug-and-play for your car.
Do I need to get this programmed by a dealer?
No. Our cloning service completely handles the programming. This saves you from the additional time and expense of a dealership visit.
How long does the whole process take?
We typically program and ship the replacement module within 24-48 hours of receiving your original BCM. Total time will depend on shipping speeds to and from our facility.
Is this a guaranteed fix for my 2014-2017 Regal BCM issues?
This module will fix problems directly caused by a faulty BCM. It’s crucial to properly diagnose the issue first, as similar symptoms can sometimes be caused by wiring or grounding problems.
What if the airbag light comes on after I install it?
This can happen on some vehicles. It simply means the airbag module needs to be electronically ‘introduced’ to the new BCM. A repair shop with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge?
No, there is no core charge. We need your original module to perform the data transfer service, but you are not required to leave it with us.
