Are you dealing with bizarre electrical issues in your 2013 Buick Regal or another compatible GM vehicle? Things like power windows with a mind of their own, flickering interior lights, a horn that won’t work, or even a frustrating no-start condition can often be traced back to a single culprit: a failing Body Control Module (BCM). As the central hub for your car’s body electronics, when the BCM goes bad, it can create a cascade of confusing and unpredictable problems. In my 20+ years as a technician, I’ve seen countless drivers spend a fortune at the dealership for what should be a straightforward fix.
This is your direct, cost-effective solution. We provide a fully functional, tested replacement BCM that is programmed with your vehicle’s exact data. The process is simple: after your purchase, we’ll provide instructions for you to send us your original BCM. We then perform a professional data transfer, cloning all the critical information (like VIN, key data, and option configurations) to the replacement unit. The result? You receive a true plug-and-play module. No expensive trips to the dealer for programming, no compatibility headaches. This is the smart way to restore your vehicle’s functionality.
From the Diagnostic Bay: The Case of the Confused Cruze
A customer brought in a 2014 Chevy Cruze with a laundry list of intermittent complaints. The radio would randomly shut off, the turn signals would sometimes work and sometimes not, and occasionally, the car wouldn’t start, just a click from the starter relay. They had already replaced the battery. My initial scan showed a slew of U-codes (communication errors), specifically pointing to lost communication with the BCM. Instead of a dead module, the BCM was failing intermittently, causing network-wide chaos. A new BCM from the dealer plus programming was quoted at over $800. We suggested this cloning service. The customer sent us their faulty BCM, we cloned it, and sent the replacement back. They installed it in 20 minutes, and every single electrical gremlin was gone. It’s a perfect example of how this service saves hundreds and provides a reliable, permanent fix.
Common Signs of a Failing GM BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security system light stays on, or the vehicle won’t recognize the key fob.
- ✔ Instrument cluster warning lights appearing for no reason.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or other U-codes.
- ✔ A no-start condition where the starter doesn’t engage, even with a good battery.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2013 Regal, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel or kick panel. Consult a service manual for your specific model if unsure.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly until they click into place.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM systems may require a ‘handshake’ after installation. Be aware of the following:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple. After you place your order, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will transfer all the necessary data to the replacement module and ship it back to you, typically within 1-2 business days.
Is this BCM truly plug-and-play?
Yes. Because we clone the data from your original module, the replacement BCM is ready for installation right out of the box. It will recognize your keys and vehicle options, eliminating the need for dealer programming.
What if my original BCM is badly damaged or won’t communicate?
In most cases, even with significant physical or water damage, we can still extract the necessary data. If we determine the data is unrecoverable, we will contact you immediately to discuss options and provide a full refund if needed.
How long does the entire process take?
We program and ship your replacement module within 24-48 hours of receiving your original part. The total time depends on shipping transit times to and from our location.
Is there a core charge or do I need to send my old part back?
There is absolutely no core charge for this item. The mail-in service is for programming only. You can keep your original module after the service is complete.
