Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange warning lights on your dash, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a wide range of frustrating and unpredictable issues. This replacement GM BCM 15063578 is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific VIN before it ships, loading it with the latest software updates from GM. This critical step ensures compatibility and saves you from expensive programming fees at a dealership or repair shop. Simply provide your VIN after purchase, and we’ll handle the rest.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security system light flashing, or the vehicle failing to start (Passlock issues).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers operating intermittently or at the wrong speed.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ Communication loss with other vehicle modules, triggering multiple diagnostic trouble codes (DTCs).

Important Post-Installation Information
While our VIN programming handles the majority of the setup, some vehicles may require minor post-installation procedures. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and can be performed by a technician with a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians will then use this VIN to flash the BCM with the correct factory software and vehicle-specific settings before we ship it to you.
Is this BCM truly plug-and-play?
For most vehicles, yes. Our VIN programming makes it ready for installation without needing a trip to the dealer. However, as noted, some models may require an airbag sync or brake pedal relearn procedure if specific warning lights appear after installation.
Will this fix my specific electrical problem?
This BCM is the solution for the most common electrical faults listed in the symptoms section. If your vehicle is experiencing one or more of those issues, there is a very high probability this part will resolve them. However, we always recommend a proper diagnosis to confirm the BCM is the point of failure.
