Is your Silverado 2500 plagued by baffling electrical problems?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC behavior, the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can create a cascade of frustrating and hard-to-diagnose issues. This OEM-quality replacement BCM, part number 15940214, is the definitive solution for restoring full electrical functionality to your 2007-2011 Chevrolet Silverado 2500 and a wide range of other GM trucks and SUVs.
Expert Pro Tip
Before replacing your BCM, always perform a thorough check of the main vehicle grounds, especially the ground strap from the engine to the frame and the primary ground point under the driver’s side door. A loose or corroded ground can cause identical symptoms to a faulty BCM and can even damage a new module if not corrected.
Symptoms of a Failing GM Body Control Module
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Unresponsive or intermittently working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, won’t turn on, or flicker randomly.
- ✔ HVAC system failure, including a blower motor that won’t work or climate controls that are inoperative.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system errors, causing no-start conditions, stalling, or misfires.
- ✔ A dashboard lit up with multiple, seemingly unrelated warning lights.

Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the main computer for your truck’s non-engine related functions. It controls power windows, locks, lights, wipers, the security system, and HVAC, ensuring all these comfort and convenience features work as they should.
Is this BCM really plug-and-play?
Yes, it is. We pre-program the module to your vehicle’s VIN, so it’s ready for installation without needing any additional programming from a dealer. This saves you time and money.
Do I need to return my old BCM?
No, there is no core charge or need to return your original part. You can dispose of it or keep it at your convenience.
What if my airbag light stays on after installing the new module?
This can happen on some models. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this part fit other GM vehicles?
Absolutely. This BCM is interchangeable with numerous part numbers and fits a wide range of GM trucks and SUVs from 2007-2013, including the Sierra, Tahoe, Yukon, Suburban, and Escalade. Please check the fitment list to confirm compatibility.
How can I be sure my BCM is the problem?
If you’re experiencing multiple, unrelated electrical issues like those listed in the symptoms section, the BCM is the most likely cause. Confirming with a diagnostic scan for BCM-specific codes is the best way to be certain before ordering.
