Is Your GM Vehicle Plagued by Bizarre Electrical Issues?
If you’re dealing with flickering lights, power windows that have a mind of their own, malfunctioning door locks, or strange warning lights on your dash, a failing Body Control Module (BCM) is often the culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Stop chasing electrical gremlins and get the definitive, hassle-free solution.
The Plug-and-Play Solution: Pre-Programmed for Your Vehicle
This isn’t just a replacement part; it’s a complete service designed to get you back on the road quickly. We take the guesswork and expense out of the equation by pre-programming this Programmed GM Body Control Module 20864768 to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This critical step ensures that the BCM communicates perfectly with your vehicle’s other electronic systems right out of the box, eliminating the need for a costly trip to the dealership for programming.
Expert Insight: Why VIN Programming is Non-Negotiable
Think of the BCM as an air traffic controller for your car’s features. It manages everything from your interior lights and power locks to the security system and instrument cluster. Every GM vehicle has a unique electronic fingerprint based on its specific options and features, all tied to the VIN. A generic, unprogrammed module is like an air traffic controller who doesn’t know the flight plan—it leads to chaos. Our VIN-specific flashing ensures every system speaks the same language, restoring function and preventing the conflicts that can arise from using a non-programmed part.

Important Post-Installation Information
While this Programmed GM Body Control Module 20864768 is designed for a simple installation, some vehicles may require additional electronic ‘relearn’ or synchronization procedures after the new module is installed. These are standard procedures that can be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync (If Needed): If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems and turn off the light.
- Brake Pedal Position Relearn (May Be Needed): On certain models, a brake pedal position sensor recalibration might be required to ensure correct brake light operation and traction control performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for programming the module correctly for your specific vehicle.
Will this fix my specific electrical problem?
This module corrects issues directly caused by a faulty BCM. Common symptoms include problems with power windows, locks, interior/exterior lighting, security system faults, and communication errors with other modules. While it solves the most common electrical issues, proper vehicle diagnostics are always recommended to confirm the BCM is the source of your problem.
Is this a difficult part to install?
The physical installation is typically straightforward for someone with moderate mechanical experience. The BCM is usually located under the dashboard. The main benefit of our service is that the complex electronic programming is already done for you, making the process much simpler than installing a blank module from a dealer.
What if my airbag light is on after installation?
This is a known possibility. It does not mean the BCM is faulty. Your vehicle’s airbag system (SDM) needs to be electronically ‘introduced’ to the new BCM. A technician with a high-level scan tool can 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 old module, which can be helpful if you ever need to reference its original part number.
