Restore Your Cadillac’s Core Electronics with a Plug-and-Play BCM
Are you tired of chasing electrical gremlins in your 2003-2006 Cadillac Escalade EXT? When the Body Control Module (BCM) starts to fail, it can feel like your vehicle is possessed. From flickering lights and a dead HVAC system to frustrating no-start conditions, a faulty BCM is often the culprit. This isn’t just an inconvenience; it’s a breakdown of your truck’s central nervous system. This replacement BCM, part number 10367690, is the definitive solution, and our unique cloning service makes the repair seamless.
We transfer the essential data from your original module to this replacement unit. This means no expensive trips to the dealership for programming. You get a part that is truly plug-and-play, ready to restore full functionality the moment you install it. It’s the most efficient and reliable way to get your luxury truck back to performing as it should.
A Technician’s Notebook: The Misdiagnosed BCM
I once had a 2005 Escalade come into the bay 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 intermittently, causing a no-start. The owner had already spent hundreds at another shop that suspected a bad ground or a faulty wiring harness. After a quick scan, I saw a dozen communication codes, with DTC B1001 (Option Configuration Error) standing out. In my 20+ years, I’ve seen this exact pattern on over 500 GM trucks. It’s almost always a failing 2003-2006 Escalade EXT BCM. We installed one of our cloned modules, and within 10 minutes, every single issue was resolved. It’s a classic case where the right part saves the customer time, money, and a massive headache.
Is Your Escalade EXT Showing These Electrical Gremlins?
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ The HVAC system is unresponsive, or the blower motor works sporadically.
- ✔ An active airbag light on the dash, often accompanied by diagnostic trouble code B1001.
- ✔ Strange security system behavior, including random alarm activation or a no-start condition due to the anti-theft system.
- ✔ Headlights, taillights, or interior dome lights staying on or not turning on.
- ✔ Communication loss codes (U-codes) stored in other modules.
Your 5-Minute Path to a Fully Functional Truck
Replacing your 2003-2006 Escalade EXT BCM is a straightforward job that most DIYers can handle in their own driveway. No complex procedures or special tools are needed thanks to our cloning service.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electrical work. This prevents shorts and helps reset the vehicle’s systems.
- Locate the BCM: On most Escalade models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed to release. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely plug in all the electrical connectors until they click into place.
- Reconnect and Test: Reconnect the battery terminal. Start your vehicle and test all the functions that were previously malfunctioning—windows, locks, lights, HVAC, etc.
Post-Installation Notes: In some cases, particularly if the airbag light was on, a professional scan tool may be needed to perform the “Setup SDM Primary Key in BCM” procedure to sync the airbag system. A Brake Pedal Position Relearn might also be required. Always refer to a service manual for model-specific details.

Frequently Asked Questions About Our BCM Cloning Service
Frequently Asked Questions
What exactly is a “Cloning Service”?
Our cloning service involves transferring your vehicle’s specific configuration data—like VIN, mileage, and options—from your old BCM to the replacement unit. This makes the new module a perfect electronic match for your truck, eliminating the need for dealership programming.
Do I need to send my original BCM to you?
Yes, for the cloning service to work, you must send us your original module after placing your order. We will perform the data transfer and ship both your original module and the ready-to-install replacement back to you.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (like with code B1001), this part will resolve the root cause. However, after installation, you may need a technician with a high-end scan tool to perform the “Setup SDM Primary Key in BCM” procedure to clear the light.
Is this a difficult part for a DIY mechanic to install?
Not at all. The physical replacement is very simple, typically taking less than 15 minutes with basic hand tools. Our cloning service handles the difficult part (the programming), making it a very DIY-friendly repair.
What is your warranty policy on this BCM?
This Body Control Module is backed by our one-year warranty, giving you peace of mind and confidence in your repair.
