Restore Your Vehicle’s Electrical System with a VIN-Programmed BCM
Are you battling frustrating electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a dead radio, or a security system that acts up on its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your car’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This isn’t just an annoyance; it can affect vehicle security and safety. Stop chasing electrical gremlins and get a definitive solution with our professionally programmed BCM.
Is Your BCM Failing? Common Symptoms:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Warning lights appearing on the dashboard for no apparent reason.
- ✔ The radio or infotainment system turning on or off by itself.
- ✔ Issues with the heating and A/C blower motor controls.
- ✔ A ‘No Communication with BCM’ error code on a diagnostic scan tool.

Installation and Post-Install Notes
Installation is straightforward for those with mechanical experience. However, please be aware of potential post-installation procedures. While our programming handles the majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. Specifically:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
There is no core charge for this part. You can keep your old module without the hassle of returning it.
Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM is a computer that acts as a central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and the radio.
Do I need to get this BCM programmed by a dealer?
No. This is the key benefit of our service. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler and saves you from additional dealership fees.
What information do you need from me?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as it is required for programming.
How do I know if this part will fit my vehicle?
This GM Body Control Module 15837419 fits a very wide range of Chevrolet, GMC, Buick, Cadillac, and Saturn vehicles. Please review the detailed fitment list on this page to confirm it matches your make, model, and year. Matching your original part number to our cross-reference list is also a great way to ensure compatibility.
What if my airbag light turns on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
