Restore Electrical Stability to Your GM Vehicle
Are you dealing with baffling electrical problems in your Buick LaCrosse, Chevy Malibu, or Cadillac SRX? Intermittent power windows, flickering lights, a security system that acts up, or even a no-start condition can often be traced back to a single component: the Body Control Module (BCM). As the central computer for your vehicle’s body electronics, a failing BCM can create a cascade of frustrating and unpredictable issues. This isn’t just an inconvenience; it’s a problem that affects your car’s daily reliability and safety systems.
Instead of facing a costly trip to the dealership that involves towing fees and expensive programming, we offer a straightforward, reliable solution. This listing is for a replacement Body Control Module, fully programmed using the data from your original unit. Our mail-in cloning service transfers all your vehicle’s specific information—including key data and security settings—directly to the replacement module. The result is a true plug-and-play part, ready for installation the moment you receive it back.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 LaCrosse with a list of strange symptoms: the radio would turn off randomly, the driver’s side window wouldn’t respond, and the remote key fob worked only occasionally. They had already replaced the battery and checked fuses with no luck. After connecting my scan tool, I saw a slew of communication error codes (U-codes) pointing to a network issue. In my 20+ years of experience, this pattern almost always points to the BCM. By isolating the BCM on the CAN bus network, we confirmed it was the source of the electrical noise. Our cloning service allowed the customer to avoid a dealership visit, and installing the programmed module resolved all the issues instantly.
Diagnosing a Faulty 2014-2016 LaCrosse BCM
A failing Body Control Module is the culprit behind many hard-to-diagnose electrical gremlins. If you’re experiencing these issues, your BCM is the likely cause. This service provides the definitive fix for your 2014-2016 LaCrosse BCM and other compatible GM models.
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ Horn, wipers, or radio functioning intermittently.
- ✔ Vehicle’s anti-theft or security system preventing the car from starting.
- ✔ False warnings on the dashboard information center.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication failures, such as U0140, U0155, or B1325.
- ✔ Inconsistent operation of the keyless entry system.
Your Straightforward Guide to Installation
Our goal is to make this repair as simple as possible. After you receive the programmed module from us, installation is a direct swap.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most compatible vehicles like the LaCrosse or Regal, the BCM is found behind the kick panel or lower dash on the driver’s side (LH). On others, like the Volt, it may be in the engine compartment. Consult your vehicle’s service manual for the exact location.
- Remove the Original Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the programmed BCM you received from us in the same location and securely reconnect all electrical harnesses.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. Note the post-installation procedures below, as some relearns may be necessary.
Important Post-Installation Steps
While our cloning makes this a plug-and-play repair, some vehicle systems may require a final handshake to sync properly. Please be aware of the following:
- 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: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for specific guidance.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer the data to the replacement unit and ship it back to you, typically within 1-2 business days. You’ll receive tracking information once it’s on its way.
Do I need to get this module programmed by a dealer?
No. Our cloning service makes this a true plug-and-play solution. All the necessary security and vehicle-specific data from your old module is transferred to the new one, so no additional dealer programming is required.
Is there a core charge for my old BCM?
No, there is no core charge. We only need your original module to perform the data cloning service. You can keep your original module after the service is complete.
What tools are needed for installation?
Basic hand tools are typically all that’s required, such as a socket set and a panel removal tool to access the BCM behind the dash or kick panel. No special electronic tools are needed for the physical installation.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire, or if it has no communication whatsoever.
