Are you battling frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, or random warning chimes can often be traced back to a single component: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and unpredictable problems. This replacement Body Control Module, compatible with part number 20839063 and many others, is the definitive solution to restore your vehicle’s functionality and your peace of mind.

This means it arrives ready for installation, loaded with the latest GM software updates to ensure optimal performance and reliability. Simply provide your VIN after purchase, and we’ll handle the complex programming before it ships.

Important Post-Installation Steps
While this module is programmed for your vehicle, some GM security and safety systems may require a ‘handshake’ procedure after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary. This ensures your brake lights and traction control system function correctly with the new module.
Disclaimer: Specific procedures can vary by vehicle model and year. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls non-engine related functions like power windows, locks, lights, the security system, and wipers. It acts as a central hub for these electronic features.
Is this BCM difficult to install?
The physical replacement is typically straightforward, often located under the dash. Since we pre-program the module to your VIN, you avoid a costly trip to the dealership for software flashing. However, some vehicles may require a simple relearn procedure for certain systems, like the airbag or brake pedal sensor, which may need a professional scan tool.
How do I provide my VIN for programming?
After you complete your purchase, please send us a message with your vehicle’s 17-digit VIN. You can also add it as a note during checkout. We cannot ship the module until we have programmed it with your specific VIN.

This BCM corrects the most common electrical failures associated with this part. If you’re experiencing issues like flickering lights, non-working power accessories, or random warning indicators, a failing BCM is the most likely cause. Proper vehicle diagnosis is always recommended to confirm the BCM is the faulty component.
Do I need to return my old BCM?
