Restore Full Electrical Function to Your Cadillac Escalade EXT
Are you dealing with frustrating and unpredictable electrical problems in your 2003-2006 Cadillac Escalade EXT? A faulty Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, unresponsive power locks, erratic HVAC behavior, or even a no-start condition. The BCM acts as the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of problems. This genuine OEM-quality replacement BCM, part number 15137394, is the definitive solution to restore your vehicle’s reliability and functionality.
Diagnosing a Failing Escalade EXT Body Control Module
A failing BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing several of the following symptoms simultaneously, there’s a strong chance your BCM is the root cause. This module is the direct fix for these common issues.
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC and climate control systems that don’t respond or have a blower motor that won’t turn off.
- ✔ Interior or exterior lights that stay on, flicker, or won’t work at all.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, including false alarms or the inability to start the vehicle.
- ✔ Inconsistent windshield wiper operation.

Installation & Post-Install Notes:
The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. While the VIN programming handles the majority of the setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on. This requires a professional-grade scan tool. Additionally, a Brake Pedal Position Relearn may be needed. No core charge is required, so you can keep your old part.

Frequently Asked Questions
What does the Body Control Module do on my 2003-2006 Escalade EXT?
The BCM is a computer that manages and controls your truck’s non-engine related electronic systems. This includes power windows, door locks, interior and exterior lighting, the security system, HVAC controls, and wipers.
Why is VIN programming necessary for this part?
VIN programming loads your vehicle’s specific configuration onto the module. This ensures all features work correctly without requiring a costly and time-consuming visit to a dealership for programming after installation.
Is this part difficult to install?
The physical installation is simple for most DIY mechanics, typically taking less than 15 minutes. It’s located under the steering column and involves unplugging the old module and plugging in the new one. No special tools are needed for the swap itself.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the BCM needs to be synced with the airbag system’s SDM module. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional diagnostic tool.
Do I have to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your original module without any hassle.
