Restore Full Control and Eliminate Electrical Headaches
If you’re dealing with the maddening electrical issues common in GM trucks and SUVs, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen countless vehicles sidelined by a faulty Body Control Module (BCM). Flickering lights, a dead HVAC system, or a security light that prevents your engine from starting—these aren’t just annoyances; they’re signs that your vehicle’s electronic nerve center is failing. This replacement 2003-2006 Escalade BCM, part number 10367690, is the definitive solution. We pre-program it to your vehicle’s specific VIN, ensuring it works perfectly right out of the box, no expensive dealership trip required.
A Technician’s Notebook: The Case of the Spooky Suburban
A customer brought in a 2005 Suburban, complaining of ‘ghosts in the machine.’ The radio would change stations, the interior lights would pulse, and the door locks would cycle while driving. They’d already replaced the battery and checked the alternator. After hooking up my scanner, I found a slew of communication DTCs pointing to the BCM. These modules are notorious for failing due to internal solder joint cracks or moisture intrusion. We installed a VIN-programmed BCM just like this one, and in under 10 minutes, every single phantom issue was gone. This isn’t just a part; it’s peace of mind and an end to diagnostic dead ends.
Is Your Escalade Showing These Electrical Gremlins?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely this module is the culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ The security or anti-theft light is on, causing a no-start condition.
- ✔ An airbag warning light on the dash, often with a B1001 DTC.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Communication errors with other modules on the vehicle’s network.
Your 5-Minute Path to a Perfect Fix
One of the best features of this module is its simple, DIY-friendly installation. You don’t need to be a master mechanic to get your truck back to 100%.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting. This prevents electrical shorts and helps reset the vehicle’s systems.
- Locate the BCM: On most Escalade, Tahoe, and Silverado models, the BCM is located under the driver’s side dashboard, near the steering column. It’s a black box with several large electrical connectors.
- Swap the Module: Carefully unplug the wiring harnesses from your old BCM. They have release tabs that need to be pressed. Remove the old module (it’s typically held by a couple of small bolts or clips) and install the new one in its place.
- Connect and Test: Securely plug the wiring harnesses into your new, pre-programmed BCM. Reconnect the battery terminal. Start the vehicle and test all functions—lights, windows, HVAC, etc.—to confirm the repair.
Post-Installation Note: In some cases, particularly if the airbag light was on, a ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool to sync the airbag system. Likewise, a Brake Pedal Position relearn might be required. These are straightforward procedures for any competent shop if needed.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and all its specific options into the module before we ship it. This ensures it communicates perfectly with your truck’s other computers, just like the original part from the factory, saving you from a costly programming service at a dealership.
Is this installation difficult for a DIYer?
Not at all. For most of the listed vehicles, the BCM is easily accessible under the driver’s side dash. With basic hand tools, the physical swap takes less than 10 minutes. Since it arrives pre-programmed, it’s a true plug-and-play repair.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can keep your old module, which saves you the time, hassle, and expense of a core charge and return shipping.
My airbag light is on. Will this fix it?
If the airbag light is caused by a communication failure with the BCM (like a B1001 code), this module will resolve the root cause. After installation, the airbag system may need to be re-synced to the new BCM using a capable scan tool to clear the light.
What is your warranty policy?
We stand behind our products with a one-year warranty. This covers any defects in the module, giving you confidence and protection for your repair.
