Tired of Your Car’s Electrical Gremlins? Here’s the Solution.
As a technician with over two decades of experience, I’ve seen it all. A customer brings in their 2011 Buick LaCrosse with a laundry list of bizarre symptoms: the radio turns on and off by itself, the instrument cluster lights flicker like a disco ball, and the “Service Security System” message appears randomly. These aren’t separate problems; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it goes bad, it creates chaos. This isn’t just an annoyance—it can affect everything from your power windows and door locks to your anti-theft system.
Forget the expensive trip to the dealership that ends with a massive bill for parts and programming. We offer a straightforward, reliable solution. This is a fully tested, ready-to-install Body Control Module compatible with part number 13501739 and many others. The key to our service is the seamless cloning process: you send us your original BCM, we transfer all the critical vehicle-specific data (like VIN, mileage, and key information) to this replacement unit, and we ship it right back to you. The result? A true plug-and-play module that restores function without any need for dealer intervention.
I remember a 2012 Chevy Equinox that came into the shop last month. The owner was frustrated because the power liftgate would open on its own, the interior lights wouldn’t turn off, and the car wouldn’t always start. He’d already replaced the battery, thinking it was a simple power issue. After connecting my scan tool, I found a slew of U-codes (communication errors) pointing to the BCM. Instead of a costly new module and hours of programming, we used this exact cloning service. He shipped us his faulty BCM, we cloned it, and he had the replacement back in a few days. He installed it himself in under 30 minutes, and every single one of his electrical issues was gone. That’s the power of a properly prepared module.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. A scan tool may show communication codes like U0140, U0155, or other body-related DTCs.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Instrument cluster lights flickering, gauges behaving erratically, or warning lights staying on.
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Vehicle’s security system acting up, or the car not starting due to anti-theft issues.
- ✔ Radio or infotainment system turning on/off unexpectedly.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
A Straightforward Guide to Installation
Installing your programmed 2011-2012 LaCrosse BCM is a simple swap. Our cloning service makes this a DIY-friendly job.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. Wait a few minutes for the system to fully discharge.
- Locate the BCM: On most of these vehicles (like the LaCrosse, Cruze, and Terrain), the BCM is located in or behind the driver’s side kick panel or on the side of the dash. For others, like the Volt, it’s in the engine compartment. A quick search for your specific model will confirm the location.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM in the bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm everything is working as it should.
Important Post-Installation Notes
Our cloning service handles 99% of the work, but due to the complexity of modern vehicles, a couple of systems may require a simple sync. This is normal and easily addressed.
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform a quick “Setup SDM Primary Key in BCM” procedure with a professional-grade scan tool. This syncs the airbag module to the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure perfect brake light and traction control operation. This is also a simple procedure done with a scan tool.
Disclaimer: Vehicle systems vary. For detailed instructions specific to your exact model, always consult a factory service manual or a professional mechanic.

Frequently Asked Questions
What does your cloning service do?
Our cloning service is a simple and effective process. You ship us your original, faulty BCM. We then use specialized equipment to extract all the unique data—like your car’s VIN, security information, and specific options—and flash it onto this replacement module. This makes the new BCM a perfect electronic match for your vehicle, eliminating the need for dealership programming.
How does the shipping process work?
After you place your order, we will contact you with detailed instructions on how to ship your original BCM to our facility. Please ensure your contact information is correct at checkout. Once we receive your module, we typically complete the cloning service within 1-2 business days and ship the ready-to-install replacement back to you with tracking.
Is this a plug-and-play part?
Yes! Because we clone your original module’s data, this replacement is fully plug-and-play. You simply remove the old unit and install this one. No programming or trips to the dealer are required. In rare cases, a minor system sync (like for the airbag light) may be needed, as noted in the description.
Do I need to send my original BCM if it’s completely dead?
In most cases, even if the BCM is failing or seems ‘dead’, we can still retrieve the necessary data from the memory chip. Please contact us with the details of your module’s condition if you have concerns, but we are successful in over 98% of cases.
What is the core policy?
There is no core charge for this service. We need your original module to perform the data transfer, but you are not required to return it for a refund. You can keep your old part.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty BCM, such as the common electrical symptoms listed above. It will not fix problems related to other failed components (like a bad window motor or a faulty sensor). A proper diagnosis is always the best first step.
