Solve Your Escalade’s Electrical Gremlins for Good
If you’re dealing with the frustrating and unpredictable electrical problems common in 2003-2006 Cadillac Escalades and other GM trucks, your Body Control Module (BCM) is the likely culprit. As a mechanic with over two decades of experience, I’ve seen firsthand how a failing BCM can wreak havoc, causing everything from flickering lights and malfunctioning power windows to a vehicle that won’t start. This isn’t just an annoyance; it’s a matter of reliability and safety. This module, part number 10367690, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
We make the repair process simple with our professional Cloning Service. You send us your original BCM, and we transfer its unique, vehicle-specific data directly to this replacement unit. This means no expensive trips to the dealership for programming. The module arrives at your door ready for a true plug-and-play installation, pre-configured to your Escalade’s VIN and options. It’s the most efficient way to fix these complex issues right the first time.
From the Diagnostic Bay
I remember a 2005 Escalade ESV that came into the shop with a laundry list of bizarre symptoms. The radio would turn on by itself, the driver’s side window wouldn’t go down, and the security light was flashing, causing an intermittent no-start. The owner had already replaced the battery and checked fuses. After connecting my scanner, I saw a dozen communication codes pointing in different directions. This is a classic sign of a failing BCM. Instead of chasing individual problems, we replaced the BCM with a cloned unit. Within 10 minutes of installation, every single issue was resolved. This is why a quality 2003-2006 Escalade BCM is a cornerstone repair for these vehicles.
Is Your Escalade Showing These Electrical Faults?
- ✔️ Erratic or non-functional interior and exterior lights.
- ✔️ Power windows, door locks, or mirrors that work intermittently or not at all.
- ✔️ HVAC system problems, such as the blower motor not working or temperature controls failing.
- ✔️ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔️ Security system malfunctions, leading to a frustrating no-start or crank-no-start condition.
- ✔️ Unexplained battery drain caused by the BCM not allowing other modules to sleep.
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 Escalade, Tahoe, and Silverado models, the BCM is located under the driver’s side dashboard, to the left of the steering column. It’s a black box with several large electrical connectors.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely plug in all the connectors. You’ll hear a click when they are properly seated.
- ✔ Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all body functions—lights, windows, locks, wipers, and HVAC—to confirm the repair was successful.
After installation, some vehicles may require a post-install procedure. For example, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a Brake Pedal Position Relearn might be necessary. Always refer to a service manual for model-specific requirements.

Frequently Asked Questions
How does the Cloning Service work?
After you place your order, you’ll receive instructions to ship your original BCM to us. We then use specialized equipment to read the vital data (like VIN, mileage, and key information) from your old module and write it onto your new one. We then ship both modules back to you, ensuring a perfect match for your vehicle.
Do I need to send my original BCM?
Yes, for the cloning service, your original module is required to extract the vehicle-specific programming. This guarantees 100% compatibility and avoids any need for dealership involvement.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). A mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. We always return your original module along with the newly programmed replacement, so you can keep it or dispose of it as you see fit.
Why should I choose this over a used BCM from a junkyard?
A used BCM will have the programming from a different vehicle, which will cause compatibility issues, security system lockouts, and incorrect feature operation. Our cloning service ensures the module is a perfect electronic match for your specific Escalade.
