Are you chasing down bizarre electrical issues in your Cadillac, Chevy, or GMC? One minute the power windows work, the next they don’t. The radio might be acting possessed, or worse, you’re facing a no-start condition due to a security system fault. As a technician with over two decades of experience, I can tell you that these frustrating, seemingly unrelated problems often point to one culprit: a failing Body Control Module (BCM).
The BCM is the central nervous system for your vehicle’s body electronics, managing everything from interior lighting and power locks to the instrument cluster and security system. When it starts to fail, it can create a cascade of baffling issues. Replacing it isn’t as simple as swapping parts; a new module from the dealership requires expensive and complex programming to sync with your vehicle’s unique identity. Our service eliminates that entire headache.
This is a professional cloning service for BCM part number 13594692. You simply send us your original, faulty BCM. We then expertly transfer 100% of its critical data—including VIN, mileage, and key programming—to this fully tested replacement module. The result? You receive a true plug-and-play solution. No dealership visits, no extra programming fees, and no core charges. It’s the most efficient and reliable way to restore your vehicle’s functionality.
Case Study: A Tricky Diagnosis
A customer brought in a 2015 Sierra 1500 with a complaint that made no sense at first: the dome light would flicker randomly, the driver’s side window would occasionally stop working, and the remote start was intermittent. They had already replaced the battery and checked grounds. After hooking up the scan tool, I saw several communication loss codes (U-codes) with various modules. This pattern immediately led me to suspect the BCM. Instead of a costly new module and programming, we used this exact cloning service. The customer shipped us their module, we cloned it, and sent the replacement back. They plugged it in, and every single issue vanished. It’s a testament to how a single component can cause widespread electrical chaos and how a direct data transfer provides a perfect fix.
Common Signs of a Failing GM Body Control Module
If your vehicle is exhibiting any of these symptoms, a faulty BCM could be the root cause. A failing module can often set Body (B-prefix) or Communication (U-prefix) Diagnostic Trouble Codes (DTCs).
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, not working, or flickering.
- ✔ Malfunctioning instrument cluster gauges or warning lights (e.g., security light).
- ✔ Remote keyless entry (RKE) or remote start failure.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Communication errors with other modules, often setting codes like U0140, U0155, or U0100.
- ✔ Vehicle’s security system preventing it from starting.
The Simple Path to a Reliable Fix: Our Cloning Process
We’ve designed our service to be as straightforward as possible for both DIYers and professional shops. After you purchase, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is accurate at checkout. Once we receive your module, our technicians will perform the data transfer to the replacement 2015 Escalade BCM and ship it back to you, typically within 1-2 business days. We provide tracking information so you know exactly when to expect your ready-to-install part.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible trucks and SUVs like the Escalade or Silverado, the BCM is located under the steering column, on the driver’s side of the dashboard. On sedans like the CTS or Impala, it may be in the LH dash area or on the firewall. Consult a service manual for your specific model’s location.
- ✔ Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. 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 replacement BCM we sent you into the bracket and securely reconnect all electrical connectors. You’ll hear a click as they lock into place.
- ✔ Reconnect Power: Reconnect the negative battery terminal.
- ✔ Test Functionality: Start the vehicle and test all the functions that were previously malfunctioning—windows, locks, lights, radio, etc. Everything should now work correctly.
Post-Installation Checks
Because we transfer your vehicle’s original data, additional programming is not typically required. However, in some cases, specific systems may need to be re-synced:
- 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 BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control performance.

Frequently Asked Questions
What does “cloning” or “programming” mean for a BCM?
Cloning is the process of reading the essential vehicle-specific data (like the VIN, security information, and feature configuration) from your original BCM and writing it directly onto the replacement module. This makes the replacement an exact digital copy, allowing it to work in your vehicle without any further programming.
Why is this service better than buying a new BCM from a dealer?
Our cloning service saves you significant time and money. A new BCM from the dealer is just a blank part; you would still need to pay for towing and expensive dealership labor to have it programmed. Our service delivers a part that is ready to install right out of the box, completely bypassing that extra step and cost.
Do I need to send you my keys?
No. Because we transfer the data directly from your original module, all of your existing keys will be recognized and will work just as they did before.
What is the turnaround time?
We pride ourselves on a fast turnaround. Once we receive your original module, the cloning process and shipping of your replacement module typically takes only 1-2 business days. We will provide you with a return tracking number as soon as it ships.
Is there a core charge for my old BCM?
No, there is absolutely no core charge. We need your original module to perform the data transfer service, but you are not required to return it after you receive the programmed replacement.
