Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your 2003-2006 Chevrolet Tahoe? Flickering lights, a non-responsive HVAC system, or power windows and locks with a mind of their own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing problems. This OEM-quality Body Control Module, part number 15137395, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Symptoms of a Failing 2003-2006 Tahoe BCM
A faulty BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC controls that are unresponsive or a blower motor that won’t turn on.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Security system malfunctions, including anti-theft activation or a no-start condition.
- ✔ Erratic windshield wiper operation.
- ✔ A variety of communication-related DTCs stored in the vehicle’s memory.
The Plug-and-Play Advantage: VIN Programming Included
Don’t waste time and money on a trip to the dealership for expensive programming. We handle the complex part for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash this module with the latest GM software specific to your vehicle. This ensures all factory-installed options work correctly right out of the box. This pre-programming is crucial for integrating the BCM with other modules in your vehicle, like the Powertrain Control Module (PCM) and Sensing and Diagnostic Module (SDM).
Installation & Post-Install Notes
Installation is straightforward for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before swapping the module is recommended. While our VIN programming makes this a plug-and-play part, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on after installation. This syncs the new BCM with the airbag system. There is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming loads your vehicle’s specific software and settings onto the BCM before it ships. This makes the module plug-and-play, avoiding a mandatory and costly trip to the dealership for programming. It ensures all your vehicle’s options work correctly.
Is this a difficult part to install myself?
For most DIYers, this is a simple installation. The BCM is usually located under the driver’s side dash and is held in by a few clips or bolts. The entire process typically takes less than 15 minutes.
My airbag light is on after installing the new BCM. What do I do?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Will this 2003-2006 Tahoe BCM fit other GM vehicles?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Silverado, Sierra, Suburban, Yukon, Escalade, and Hummer H2. Please check the detailed fitment list on this page to confirm compatibility with your exact model.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and shipping costs.
