Restore Your Vehicle’s Electrical System and Drive with Confidence
Are you battling frustrating electrical gremlins in your GM truck or SUV? Flickering interior lights, unpredictable power windows and locks, a security light that won’t turn off, or a mysterious battery drain that leaves you stranded are all classic signs of a failing Body Control Module (BCM).

- Interior dome lights or dashboard lights staying on or not working at all
- The security or anti-theft system acting erratically or preventing the engine from starting
- A parasitic battery drain that kills your battery overnight

Expert Insight: The BCM as Your Vehicle’s ‘Nervous System’
Think of the BCM as the central nervous system for your truck’s comfort and convenience features. It doesn’t control the engine, but it manages almost everything else you interact with daily—from the chime that reminds you your lights are on to the power locks that keep you secure. When it fails, communication breaks down. That’s why a simple BCM issue can manifest as multiple, unrelated problems. By installing a freshly programmed unit, you’re not just replacing a part; you’re restoring clear, reliable communication between all your vehicle’s electronic systems.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine-related functions. This includes power windows, power door locks, interior and exterior lighting, the anti-theft system, and dashboard warning chimes.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. Our technicians will use this number to flash the module with the correct software for your specific vehicle before shipping it out.
Is this a difficult part to install?
For most of the listed vehicles, the BCM is located under the dashboard and is accessible with basic hand tools. Because our module is pre-programmed, the physical installation is typically a straightforward plug-and-play process. However, we always recommend consulting a service manual or a professional technician if you are unsure.
Do I need to send my old part back?
No. This purchase has no core charge. You can keep your original module without any additional fees or hassle.
What if my airbag light is on after I install the BCM?
In some cases, the new BCM may need to be electronically synced with the airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a repair shop with a professional-grade scan tool.
Will this GM Body Control Module 16257125 fix my specific problem?
This module is a direct solution for failures of the BCM itself. If your vehicle is experiencing the common symptoms listed above, this part is very likely the solution. For a definitive diagnosis, it is always best to have a qualified technician inspect the vehicle.
