Restore Your Vehicle’s Brain without the Dealership Headache
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or worse—a truck that won’t start? These are classic signs of a failing Body Control Module (BCM). Before you resign yourself to a costly and time-consuming visit to the dealership, we have a straightforward, reliable solution. This is a replacement BCM, compatible with part numbers including 13594692 and 13591519, that arrives at your door ready for installation, thanks to our professional cloning service.
The BCM is the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of frustrating and unpredictable problems. Our service eliminates the biggest hurdle in BCM replacement: programming. By sending us your original module, we meticulously transfer all of its critical data—including VIN, key information, and specific options—to this replacement unit. The result? A true plug-and-play module that restores full functionality without requiring any additional programming or expensive scan tools. It’s the smart fix for both savvy DIYers and professional technicians looking to save time and money.
A Technician’s Notebook: The Intermittent Gremlin
I remember a 2015 Sierra 2500 that came into the shop with a laundry list of complaints from the owner. The radio would turn off randomly, the dome light would flicker while driving, and occasionally, the truck would refuse to crank. He’d been to two other shops that couldn’t find the issue because it was so intermittent. After connecting our diagnostic tool, we found a slew of communication error codes (U-codes) pointing to the BCM. Instead of risking a new, unprogrammed module from the dealer, we used a cloned BCM. The customer mailed in his original, we transferred the data, and sent the replacement back. He installed it in his driveway in under 30 minutes. The truck has been flawless ever since. It’s a perfect example of how cloning provides a definitive, hassle-free repair.
Common Signs of a Failing GM BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ The horn honks unexpectedly or the alarm goes off randomly.
- ✔ Wipers operate on their own or don’t work at all.
- ✔ Multiple communication error codes stored, such as U0140, U0155, or other U-series codes.
- ✔ A dashboard that lights up like a Christmas tree with unrelated warning lights.
Your Straightforward BCM Swap Guide
- ✔ Place Your Order: Purchase this BCM cloning service. We will then contact you with shipping instructions for your original module.
- ✔ Remove Your Original BCM: On most GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. Disconnect the negative battery terminal first, then carefully unplug the electrical connectors and remove the module.
- ✔ Ship Us Your Module: Securely package your original BCM and ship it to our facility using the provided address.
- ✔ We Handle the Rest: Upon receipt, our technicians will clone all necessary data to the replacement module within 1-2 business days and ship it back to you.
- ✔ Install and Verify: Install the newly programmed BCM, reconnect the battery, and start your vehicle. Test all body functions (lights, windows, locks) to confirm the repair.
Important Post-Installation Checks
While our cloning service makes this a nearly plug-and-play process, some GM vehicles may require minor system initializations after the BCM is replaced. These are not always necessary but are good to be aware of:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This re-establishes communication between the airbag system and the new BCM.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and stability control function.
Disclaimer: Always consult a factory service manual for procedures specific to your vehicle’s year and model. No core charge is required; you can keep your old module.

Frequently Asked Questions
How exactly does the mail-in cloning service work?
After you purchase, we provide you with an address to ship your original BCM. Once we receive it, we use specialized equipment to read the unique programming and security data from your module and write it directly onto the replacement unit. This makes the new module an exact electronic copy of your old one.
What is the total turnaround time?
We typically clone and ship the replacement module within 24-48 hours of receiving your original BCM. The total time depends on your shipping speed to and from our facility.
Do I need to do any programming myself?
No. The entire point of our service is to handle the programming for you. The BCM you receive back will be ready to install and function immediately, saving you a trip to the dealer.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is causing major issues, the core data on the memory chip is still readable. Please contact us before ordering if your module is severely damaged (e.g., by water or fire) so we can assess the likelihood of a successful data transfer.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your original part back to us after the repair, though we need it initially for the cloning process.
