Tired of Electrical Gremlins in Your GM Truck?
Is your trusty Silverado, Sierra, or S10 suddenly acting possessed? Flickering lights, power windows with a mind of their own, a security light that won’t turn off, or worse, a truck that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command for your truck’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable issues. Stop chasing symptoms and replace the core of the problem with this reliable, pre-programmed BCM.
Common Symptoms & Your Solution
If you’re experiencing any of the following, a failing BCM is the likely cause:
- Intermittent or non-working power windows, door locks, or interior lights.
- The security or anti-theft light stays on, preventing the engine from starting.
- Erratic gauge cluster behavior or warning lights that come and go.
- Communication error codes (U-codes) when scanned with a diagnostic tool.
- Remote keyless entry system not functioning correctly.

We take a quality BCM and program it with the latest official GM software, tailored specifically to your truck’s Vehicle Identification Number (VIN).

Expert Insight: The Brains of Your Truck’s Body
Think of the BCM as the central nervous system for everything in your truck that isn’t directly related to the engine. On these GMT800-platform trucks, it manages a huge number of functions—from the simple chime when you leave your keys in the ignition to the complex logic of the PassLock security system. When it starts to fail, the symptoms can seem random and unrelated, leading many owners down expensive diagnostic rabbit holes, replacing perfectly good switches and motors. By replacing the faulty 1999-2000 Silverado 2500 Body Control Module with a correctly programmed unit, you’re restoring the central hub of communication, ensuring all those components work together as the factory intended.
Don’t let a faulty module dictate when your truck works. Take control with this plug-and-play solution designed for the hardworking owner. By providing us with your VIN at checkout, you ensure that the 1999-2000 Silverado 2500 Body Control Module you receive is prepared for your exact vehicle configuration, making the repair as straightforward as possible.
Frequently Asked Questions
What does the Body Control Module (BCM) actually do?
The BCM is a computer that supervises and controls the functions of your vehicle’s body electronics. This includes power windows, power locks, interior and exterior lighting, the alarm system, keyless entry, and instrument panel warnings.
Is this part truly plug and play?
Because we program it to your VIN, it is as close to plug-and-play as possible and will not require dealer programming. However, in some cases, minor post-installation procedures like an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be necessary. These are standard procedures for this type of repair and can be performed with a capable diagnostic tool.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive your VIN.
Will this fix my specific electrical problem?
This module fixes issues directly caused by a failing BCM. The symptoms listed in our description are the most common indicators. While we cannot diagnose your truck remotely, if you are experiencing multiple of those symptoms, the BCM is the most probable cause.
What if my airbag light is on after installation?
This can happen occasionally. It simply means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool to sync the modules and turn off the light.
Do I have to send my old BCM back?
No. This product has no core charge. You can keep, discard, or recycle your original part at your convenience.
