An Expert’s Diagnostic Tip
As a technician, I’ve seen countless hours and dollars wasted when owners or shops try to fix BCM-related symptoms one by one. They’ll replace a window switch, then a door lock actuator, then a blower motor resistor, only to find the problem persists or moves elsewhere. The issue isn’t the individual components; it’s the central computer that controls them. A proper diagnosis often reveals communication errors with the BCM. Replacing the BCM, especially a pre-programmed unit like this one, is often the most efficient and cost-effective way to solve the entire cluster of problems at once.
By installing our expertly prepared 2003-2007 Sierra Denali Body Control Module, you’re not just buying a part; you’re investing in a permanent solution that brings back the comfort, convenience, and reliability you depend on.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer after installation?
No. The main benefit of our service is that this Body Control Module arrives at your door pre-programmed to your vehicle’s specific VIN. This makes it a true plug-and-play solution, eliminating the need for any additional programming or calibration at a dealership.
What tools are required for installation?
Installation is typically very straightforward and can be completed in under 10 minutes with basic hand tools. You will likely only need a socket set or nut driver to remove the lower dash panel and the module’s mounting bolts. Always remember to disconnect the vehicle’s battery before starting the replacement.
Will this module fix my airbag warning light?
This BCM will resolve any BCM-related trouble codes (like B1001) that are causing the airbag light. However, in some vehicles, the new BCM and the airbag’s Sensing and Diagnostic Module (SDM) need to be synchronized. If the light remains on after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
Is there a core charge for my old part?
No, there is no core charge associated with this module. You can keep your old part without any hassle or need to return it.
My original part number isn’t an exact match. Will this still work?
Yes, most likely. This module is a direct replacement for a long list of interchangeable GM part numbers, including 15116066, 15136225, 15198116, and others. As long as your vehicle’s year, make, and model are on our compatibility list, this VIN-programmed module is the correct fit.
Where is the BCM located on my 2003-2007 Sierra Denali?
