Is your Silverado, Sierra, or Tahoe plagued by strange electrical issues? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your truck’s body electronics, managing everything from your power windows and door locks to the interior lights and HVAC system. When it begins to fail, it can create a cascade of frustrating and seemingly unrelated problems. This genuine OEM-quality GM Body Control Module, interchangeable with part number 15284816, is the definitive solution to restore full electrical functionality to your vehicle.
We take the guesswork and dealership hassle out of the repair. Each module is expertly programmed to your vehicle’s specific VIN before shipping, ensuring a true plug-and-play installation. This critical step guarantees that the BCM communicates flawlessly with your truck’s other electronic systems, eliminating the need for expensive dealer programming or special tools for basic installation.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ HVAC system malfunctions, such as the blower motor not working or temperature controls being unresponsive.
- ✔ The security system acting up, causing random alarm triggers or preventing the engine from starting.
- ✔ An airbag warning light on the dash, often with a DTC B1001 code stored.
- ✔ Intermittent stalling, misfires, or other performance issues related to poor data communication.
- ✔ A battery that repeatedly dies due to a parasitic electrical draw.

Installation and Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column. The physical replacement is straightforward and can often be completed in under 15 minutes. However, please be aware of potential post-installation procedures that may be required for your specific vehicle:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

How do I know if my BCM is actually bad?

Where is the BCM located on my 2013 Silverado?
