Tired of Chasing Electrical Gremlins?
Are you dealing with frustrating, intermittent electrical issues in your GM truck, van, or SUV? Flickering lights, unresponsive power windows, faulty door locks, or a security system that has a mind of its own?

This module is the reliable, cost-effective way to restore full functionality and get your vehicle back to dependable working order.

A failing BCM can wreak havoc on your vehicle’s electronics. If you’re experiencing any of the following, this part is your answer:
- Power windows, mirrors, or door locks working intermittently or not at all.
- Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- The security system or keyless entry failing to operate correctly.
- Erratic instrument cluster behavior or warning lights.
- Communication issues with other modules, often triggering various Diagnostic Trouble Codes (DTCs).

Expert Insight: The Brains of Your Vehicle’s Body
Think of the BCM as the central nervous system for all the non-engine electronics in your truck. It’s the command center that tells your power windows to roll down, your interior lights to turn on, and your doors to lock. When it fails, communication breaks down, leading to the chaotic symptoms you’re seeing. In the past, replacing one meant the vehicle had to be towed to a dealer for programming. Our service of providing a programmed 15063578 BCM is a game-changer for DIY mechanics and independent shops, turning a complex, expensive repair into a manageable, direct replacement.

Important Post-Installation Information
While this module is programmed for your VIN, some vehicles may require one or two simple relearn procedures after installation to sync with other onboard systems. These are standard procedures that can be performed by any competent technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be necessary on some models to ensure proper brake light and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s body and electrical functions that are not related to the engine. This includes power windows, door locks, interior/exterior lighting, the security system, and the instrument panel warnings.
How do I know for sure that my BCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis from a qualified technician using a professional scan tool is always the best practice. A faulty BCM will often set specific diagnostic trouble codes (DTCs) and fail communication tests.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. We cannot ship the module until we have this information. Once we receive your VIN, our technicians will program the BCM with the latest GM software specific to your vehicle and ship it out to you.
Is this part difficult to install?
The physical installation is typically straightforward for someone with moderate mechanical experience. The BCM is usually located under the dashboard or steering column. The main benefit of our programmed 15063578 BCM is that it eliminates the most difficult part—the electronic programming.
Do I need to send my old BCM back?
No. This product comes with no core charge, so you are free to keep or dispose of your original module as you see fit. There is nothing to send back to us.
Will any other keys or remotes need to be reprogrammed?
In most cases for this vehicle generation, the key and remote programming is stored within the BCM. Since this unit is programmed to your VIN, your existing keys and remotes should work without any additional programming required. However, it’s always a good idea to test all keys and remotes after installation.
