Restore Your Vehicle’s Electrical System with a Perfectly Matched BCM
Are you battling a storm of bizarre electrical problems in your car? Flickering lights, malfunctioning power windows, a security system that acts up, or even a vehicle that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can create chaos. This isn’t just an inconvenience; it can be a major source of frustration and diagnostic headaches. Forget the dealership’s high costs and complex programming appointments. We offer a straightforward, reliable solution.
This listing is for a comprehensive programming service for a replacement BCM compatible with part number 13577924. The process is simple: you purchase this service, send us your original BCM, and we transfer all of its critical data—including VIN, mileage, and vehicle-specific options—to a replacement unit. We then ship the fully programmed, plug-and-play module back to you. This ensures a seamless installation and restores your car’s functions precisely as the factory intended.
From the Diagnostic Bay: The Case of the Haunted LaCrosse
A few months back, a 2012 LaCrosse came into my shop with a list of symptoms 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 wouldn’t recognize the key fob. The owner had already replaced the battery and checked all the fuses. After connecting my scanner, I saw a slew of communication error codes, primarily a U0140 (Lost Communication With Body Control Module). In my 20+ years of experience, this pattern almost always points to an internal BCM failure. Instead of a costly new module and hours of dealer programming, we opted for a cloned BCM. We had the customer’s original module cloned, and upon installation, every single phantom issue vanished. It’s a perfect example of how a precisely programmed module is the most effective fix.
Common Signs of a Failing GM Body Control Module
If your vehicle is exhibiting any of these symptoms, a failing BCM is the likely cause. A failing module can store diagnostic trouble codes (DTCs) like U0140, U0155, or various B-codes related to specific body functions.
- ✔ Unpredictable power window or door lock operation
- ✔ Interior or exterior lights flickering, staying on, or not working at all
- ✔ The anti-theft or security light flashing, preventing the car from starting
- ✔ Horn honking unexpectedly or not working when pressed
- ✔ Wipers activating on their own or not responding
- ✔ Instrument cluster gauges behaving erratically or going dark
- ✔ Communication errors with diagnostic scan tools
Your Straightforward Installation Guide
Installing your programmed BCM is a direct replacement process. While the exact location varies by model, the steps are generally consistent.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On a 2011 Regal, the BCM is typically found in the left-hand (driver’s side) dash area. For other models, it may be in the kick panel, under the center console, or in the engine compartment. Consult your owner’s manual or a service guide if you’re unsure.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be pressed to release. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location and reconnect all the electrical harnesses securely. Ensure each connector clicks into place.
- Reconnect Power: Reattach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body electronics: windows, locks, lights, wipers, and radio to confirm proper operation.
Important Post-Installation Information
Our cloning service makes this as close to plug-and-play as possible. However, in some GM vehicles, a couple of quick relearn procedures may be needed after installation. This is normal and ensures all related systems communicate correctly.
- Airbag System Sync: If you see an airbag warning light on your dash after installation, the Sensing and Diagnostic Module (SDM) needs to be re-synced with the new BCM. This is done via a ‘Setup SDM Primary Key in BCM’ procedure using a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control system function correctly, a brake pedal position sensor recalibration might be necessary on certain models.
Disclaimer: Vehicle systems can be complex. We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the process.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your car that controls most of the non-engine related electronic functions. Think of it as the brain for your power windows, locks, lights, security system, wipers, and other interior accessories.
Why is your cloning service better than buying a new BCM?
A new BCM from the dealership is a blank slate. It requires expensive, specialized tools and software to be programmed to your car’s specific VIN and options. Our cloning service transfers all this data from your original module, making the replacement plug-and-play and saving you hundreds in dealer fees.
How does the mail-in process work?
It’s simple. After you place your order, we will contact you with shipping instructions. You mail your original BCM to us. Once we receive it, we perform the cloning service within 1-2 business days and ship the newly programmed replacement BCM back to you with tracking.
Do I have to send my keys or any other parts?
No, we only need your original Body Control Module. All the necessary key data and security information is stored within the module itself, which we will transfer to the replacement unit.
What if the airbag light comes on after I install it?
This is a possibility on some GM models. It simply means the airbag system (SDM) 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 in a few minutes to resolve this.
Is there a core charge for this part?
No, there is no core charge. We only need your original module to perform the programming service. You can keep your original, non-working module after the service is complete.
