End Frustrating Electrical Problems in Your GM Truck or SUV
Are strange electrical issues making your trusted GM vehicle feel unreliable? Flickering lights, power windows with a mind of their own, a security system that acts up, or random warning chimes are classic signs of a failing Body Control Module (BCM). This central computer is the brain behind your vehicle’s body electronics, and when it falters, it can cause a cascade of confusing problems. Stop chasing electrical gremlins and restore your vehicle’s proper function with this direct-fit, professionally programmed BCM.

- Intermittent or non-working power windows, door locks, or mirrors
- Interior dome lights or dashboard lights staying on or not working at all
- Erratic windshield wiper or turn signal operation

Expert Insight from a 20-Year Technician
“I’ve seen countless DIY mechanics and even professional shops waste hours trying to diagnose these exact symptoms. They’ll replace switches, check grounds, and chase wires, all because they suspect something other than the BCM. The reality is, on these early 2000s GM platforms, the BCM is a very common point of failure. The real magic of this solution is the VIN programming. Getting a Programmed 15063578 BCM delivered to your door turns a potentially complex electronic repair into a manageable parts swap. It’s the smartest, most efficient way to get your truck or SUV back to 100%.”
Important Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control function.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors many of the electronic accessories not related to the engine, such as power windows, locks, interior and exterior lighting, security systems, and wipers. It’s the command center for your vehicle’s comfort and convenience features.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN, as we use it to load the correct, vehicle-specific software onto your new BCM.
Is this part difficult to install?
For someone with basic mechanical skills, the installation is typically straightforward. The BCM is usually located under the dashboard, often near the steering column or center console. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. The most critical part is that our service pre-programs the module, which is the step that usually requires a dealership.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module, which saves you the hassle and expense of return shipping.
What if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A qualified technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this Programmed 15063578 BCM fix my specific problem?
This module is the definitive solution for failures within the BCM itself, which cause the many symptoms listed above. While it fixes a very common set of electrical issues on these GM trucks and SUVs, proper vehicle diagnosis is always recommended to rule out other potential causes like wiring or switch failures.
