Are you chasing electrical gremlins in your 2014-2017 Buick Regal? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or a frustrating no-start condition can often be traced back to one component: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, when the BCM starts to fail, it can create a cascade of baffling issues. This isn’t just an inconvenience; it can affect your car’s security and basic functions.
Instead of paying steep dealership prices for a new module and programming, or taking a gamble on a junkyard part that won’t work without a trip to the dealer anyway, we offer a reliable, cost-effective solution. This is a mail-in cloning service for your 2014-2017 Regal BCM. We transfer the unique, vehicle-specific data from your original BCM directly onto a fully tested replacement unit. The result? You receive a module that is 100% plug-and-play, ready for installation right out of the box—no additional programming required.
A Technician’s Notebook: The Case of the Haunted Regal
A customer brought in a 2015 Regal with a list of complaints that sounded like something out of a ghost story. The interior lights would fade in and out randomly, the radio would shut off, and occasionally, the car just wouldn’t start. They had already replaced the battery and checked the alternator. After hooking up my scanner, I saw a slew of U-codes, specifically U0140 (Lost Communication with BCM). In my 20+ years of experience, intermittent communication loss like this almost always points to an internal failure in the module itself. Instead of a costly new BCM from the dealer, we performed a cloning service just like this one. The customer got their car back two days later, and the ‘ghost’ was gone for good. This service is the most direct fix for these exact symptoms.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the culprit. A failing 2014-2017 Regal BCM can cause more than just one of these issues at a time.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light is on, or the alarm activates randomly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Communication error codes stored, such as U0140, U0155, or other U-codes.
- ✔ Intermittent no-start condition where the engine cranks but won’t fire up.
A Straightforward Guide to Installation
Installing your newly programmed BCM is a simple process. In the 2014-2017 Regal, the BCM is located on the left-hand (driver’s) side of the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Access the BCM by removing the necessary trim panels on the driver’s side of the dashboard. It is typically mounted to a bracket in this area.
- Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your replacement BCM in the same location and securely reconnect all the electrical connectors you just removed.
- Final Steps: Reconnect the negative battery terminal. Start the vehicle to confirm that the issues are resolved.
Important Post-Installation Information
While our cloning service makes this a plug-and-play process, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is resolved with a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool. This syncs the airbag system with the BCM.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be needed to ensure your brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does this mail-in cloning service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the critical data and flash it onto a replacement module. We then ship the ready-to-install BCM back to you. This process ensures all your car’s settings and key information are preserved.
Is this better than buying a used BCM from a salvage yard?
Absolutely. A used BCM from another vehicle contains the wrong Vehicle Identification Number (VIN) and security data. It will not work in your car without being reprogrammed by a dealer, which adds significant cost and hassle. Our service provides you with a module that is already matched to your specific vehicle.
Will I need to do any programming after I install it?
No, the primary programming is complete. The module will be plug-and-play. However, as noted above, some vehicles may require minor relearn procedures for systems like the airbags or brake pedal sensor, which can be performed with a suitable scan tool if necessary.
What is the turnaround time for this service?
We pride ourselves on a fast turnaround. We will program and ship your replacement module within 1-2 business days of receiving your original BCM. We will send you tracking information as soon as it ships.
Do I need to send back my original part after installation?
No, there is no core charge for this service. You can keep your original, non-working module.
