Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the central computer for your truck’s body electronics. It manages non-engine related functions like power windows, power door locks, interior and exterior lighting, the security system, wipers, and even parts of the HVAC system. When it fails, you experience a wide range of electrical problems.
Is this BCM truly “plug-and-play”?
Yes. We program the module to your vehicle’s VIN before shipping it. This ensures it communicates correctly with your truck’s other computers right out of the box, eliminating the need for additional programming by a dealer.
Where is the BCM located on my 2005 Silverado?
On most 2003-2007 Silverado, Sierra, Tahoe, and Suburban models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s typically a black plastic box with several large electrical connectors.
Will this fix my airbag light?
This module can resolve BCM-related DTCs that may trigger the airbag light. However, if the light remains on after installation, a simple “Setup SDM Primary Key in BCM” procedure may need to be performed with a professional scan tool to sync the new BCM with the airbag system. This is a common final step for this repair.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which simplifies the repair process for you.
How do I know if my BCM is bad?
Common signs of a failing BCM include multiple, unrelated electrical problems happening at once, such as flickering lights, malfunctioning power accessories, and security system alerts. A professional diagnosis with a high-end scan tool can confirm the failure by checking for communication errors and specific BCM-related trouble codes.
