Restore Your Truck’s Electrical System with a VIN-Programmed BCM
Are you battling bizarre electrical issues in your Chevrolet Silverado, GMC Sierra, or other compatible GM truck? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle.
This is a direct-fit replacement Body Control Module, delivered to you pre-programmed to your vehicle’s specific VIN. This crucial programming step ensures that the module communicates perfectly with your truck’s existing systems right out of the box, eliminating the need for an expensive trip to the dealership for software flashing. We install the latest GM software updates, so you’re getting a module that’s ready to perform reliably for years to come. Simply provide your VIN after purchase, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from the interior dome lights or dashboard backlighting.
- ✔ The security system or anti-theft light staying on, preventing the truck from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar”).
- ✔ Wipers operating incorrectly or not parking in the correct position.
- ✔ Communication errors with other modules when read with a diagnostic scanner.
Installation and Post-Install Procedures for your 1999-2000 Silverado BCM
Replacing the BCM is a straightforward process for a seasoned DIYer or any professional technician. The module is typically located under the driver’s side of the dashboard. After disconnecting the battery, you can unplug the electrical connectors, unbolt the old module, and install the new one. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required after installation.
Post-Installation Syncing:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after the new BCM is installed. This is because the BCM needs to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear this light.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure the brake lights and traction control system function correctly. This procedure can also be completed with a compatible diagnostic tool.
Please Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your truck’s non-engine-related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and more.
Why do you need my VIN to program the BCM?
Your vehicle’s VIN (Vehicle Identification Number) allows us to load the exact software and settings your truck was built with. This ensures seamless communication with other modules and enables all the specific features and options for your trim level, preventing compatibility issues.
Is this part difficult to install?
The physical installation is relatively simple, involving unplugging and unbolting the old unit and putting the new one in its place. However, as noted, some vehicles may require post-installation electronic procedures with a professional scan tool to sync the airbag or brake systems.
What happens if the airbag light comes on after installation?
If the airbag light is on, it means the new BCM needs to be electronically introduced to the vehicle’s airbag computer (SDM). A repair shop with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
How can I be sure this fits my vehicle?
This BCM fits a wide range of GM models listed in the description, including the 1999-2000 Silverado, Sierra, S10, Blazer, and more. Please match your original part number to one of the compatible numbers listed (e.g., 16257125, 8093668010) to confirm fitment.
