Is Your Buick Regal Experiencing Bizarre Electrical Problems?
If your 2013 Buick Regal is acting possessed—with flickering lights, malfunctioning power windows, a dead instrument cluster, or a no-start condition—the Body Control Module (BCM) is the likely culprit. As the central nervous system for your vehicle’s electronics, a failing BCM can cause a cascade of frustrating and seemingly unrelated issues. In my two decades as a technician, I’ve seen these modules cause headaches for both owners and mechanics, often leading to expensive, incorrect diagnoses.
Forget the dealership hassle and the exorbitant cost of programming a new module from scratch. Our professional cloning service is the most efficient and reliable solution. We transfer the critical data from your original, faulty BCM directly onto this replacement unit. The result? A true plug-and-play module that restores full functionality to your vehicle without any additional programming required. It arrives ready to install, saving you time, money, and a trip to the dealer.
From the Diagnostic Bay: The Case of the Phantom Drain
A customer brought in a 2013 Regal with a classic, infuriating problem: the battery would be dead every morning. They had already replaced the battery and the alternator. After checking for parasitic draws, I traced the issue to the BCM. It wasn’t fully ‘going to sleep’ after the car was turned off, causing a slow but steady drain on the battery. A new BCM from the dealer, plus programming, was quoted at over $800. We used a cloned module instead. The total repair was a fraction of the cost, and the phantom drain was gone for good. This is a textbook failure I’ve seen dozens of times on this GM platform.
Common Signs of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ Erratic instrument cluster behavior, with gauges dropping out or warning lights flashing randomly.
- ✔ The security or anti-theft system preventing the car from starting.
- ✔ Communication issues with diagnostic scan tools (e.g., U-codes like U0140).
- ✔ Wipers or turn signals activating on their own or not working at all.
- ✔ Inconsistent A/C and climate control operation.
A Straightforward Guide to BCM Replacement
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2013 Regal, the BCM is typically located on the left-hand (driver’s) side of the dashboard. Access may require removing the lower dash panel.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the module. Press the release tabs firmly. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- ✔ Ship Your Original Module: After placing your order, we will provide instructions for shipping your original BCM to our facility. We handle the rest!
- ✔ Install the Cloned Module: Once you receive your cloned replacement BCM and your original unit back from us, simply mount it in place, reconnect the electrical connectors, and re-secure the negative battery terminal.
- ✔ Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform a post-installation procedure like an Airbag System Sync or Brake Pedal Position Relearn if specific warning lights are present.

Frequently Asked Questions
How does the cloning service work?
After you purchase, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, we extract the essential vehicle data and program it onto the replacement module. We then ship both your original module and the ready-to-install replacement back to you.
Will I need to get this programmed by a dealer?
No. The entire point of our service is to avoid dealer programming. Because we clone your original data, the replacement module is plug-and-play. It will work with your existing keys and vehicle configuration right out of the box.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, the core data on the memory chip is still readable. We have specialized tools to extract this data. If for some reason the data is completely corrupted and unreadable, we will contact you to discuss options and provide a full refund.
What is the ‘Airbag System Sync’ mentioned in the description?
The BCM communicates with the airbag system (SDM). Sometimes after a BCM replacement, the airbag warning light will illuminate. This is not a fault, but a security handshake that needs to be reset. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Do you keep my old BCM?
No. We always return your original module along with the programmed replacement unit. We do not require a core and do not keep your old parts.
