Restore Full Electronic Functionality to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2003-2006 Cadillac Escalade EXT? Symptoms like flickering lights, unresponsive power windows and locks, erratic HVAC behavior, or a persistent airbag light can often be traced back to a single, failing component: the Body Control Module (BCM). This module acts as the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of confusing issues. This OEM-quality BCM, part number 10367690, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
- ✔ HVAC system malfunctions, including loss of blower control or incorrect temperature blending.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system acting up, leading to no-start conditions or false alarms.
- ✔ A variety of seemingly unrelated electrical issues occurring simultaneously.
- ✔ Diagnostic Trouble Codes (DTCs) related to body systems stored in the vehicle’s memory.

Post-Installation Procedures
While installation is simple, some GM vehicles may require a ‘re-sync’ procedure for certain systems after the new BCM is installed. In most cases, the vehicle will operate perfectly. However, if you notice the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. In some cases, a ‘Brake Pedal Position Relearn’ may also be needed. These are standard procedures for this type of repair.
Frequently Asked Questions
What does the Body Control Module do on my Escalade?
The BCM is a computer that manages and controls your vehicle’s body electronics. This includes power windows, locks, interior and exterior lighting, wipers, the security system, and the HVAC system.
Is this BCM ready to install when I receive it?
Yes! This module is sold with VIN programming. We program it with your vehicle’s VIN before shipping, so it’s ready for a plug-and-play installation without requiring a visit to the dealership.
Where is the BCM located on a 2004 Escalade EXT?
On the 2003-2006 Cadillac Escalade EXT, as well as most compatible GM trucks and SUVs like the Silverado and Tahoe, the BCM is located under the steering column on the driver’s side of the dashboard.
What if my airbag light is on after installing the new BCM?
If the airbag light stays on, the BCM needs to be electronically synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which is convenient if you ever need to reference it.
Will this part fit a 2005 GMC Sierra or a 2006 Chevy Suburban?
