Are you battling frustrating electrical issues in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? A faulty Body Control Module (BCM) is often the culprit behind a cascade of problems, from flickering lights and unresponsive windows to a non-functional HVAC system. The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can make your daily drive unpredictable and unsafe. This genuine quality GM Body Control Module, part number 15263363 (interchangeable with 25844480 and others), is the definitive solution to restore your vehicle’s electronic stability and performance.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures seamless communication with your vehicle’s other electronic systems right out of the box. You can bypass expensive dealership programming fees and lengthy wait times, getting your truck or SUV back to perfect working order with a simple, plug-and-play installation.
Is Your Body Control Module Failing?
A failing BCM can manifest in numerous ways, often mistaken for other component failures. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Strange electrical behavior, such as interior or exterior lights not working, flickering, or staying on.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ HVAC system problems, including a blower motor that won’t turn on or can’t be controlled.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, causing no-start conditions or random alarm activation.
- ✔ Communication errors between various electronic modules on the vehicle’s data network.
Solving Issues with Your Escalade Body Control Module
This pre-programmed module is engineered to resolve the complex issues caused by a faulty factory unit. By installing this part, you are not just replacing a component but restoring the core of your vehicle’s comfort, convenience, and security systems. The VIN-specific programming ensures that all factory-installed options on your Escalade Body Control Module network function exactly as they were designed to, from the heated seats to the remote start system. We load the latest GM software updates, which can often correct underlying firmware bugs that may have existed in your original module.
Installation and Post-Install Procedures
Physically installing the BCM is straightforward for most DIY mechanics. It is typically located under the driver’s side dashboard, near the steering column, and can be swapped in minutes. However, after installation, some vehicles may require additional electronic steps:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control functionality.
We make the process easier with a no-core-charge policy, so you don’t have to worry about the cost or hassle of returning your old part.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s specific VIN and factory options into the module before we ship it. This makes the BCM a true plug-and-play part, as it’s already configured to work with your truck’s unique features, saving you a trip to the dealer for expensive programming.
Will this fix my airbag light with code B1001?
This module will correct the fault that causes the B1001 code. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new module with the airbag system and clear the light.
Where is the BCM located on my 2009 Escalade?
The Body Control Module is located under the driver’s side of the dashboard, typically mounted to the left of the steering column. Access usually requires removing the lower dash panel.
Do I need to send my old BCM back?
No. This part is sold with no core charge. You can keep your original module without any additional fees or hassle.
What if my electrical problems continue after installation?
While a faulty BCM is the most common cause, persistent issues could indicate other problems, such as a poor ground connection or a wiring harness issue. We recommend checking the main BCM ground connections during installation, as this is a frequent secondary problem.
