Are you experiencing a cascade of bizarre electrical problems in your GM truck or van? Issues like flickering lights, malfunctioning power windows, a dead HVAC system, or a persistent airbag light are classic signs of 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 make your vehicle feel unpredictable and unsafe. This VIN-programmed BCM, part number 15198116, is the direct-fit, reliable solution to restore full functionality and peace of mind.
From the Diagnostic Bay
We had a 2006 Silverado 2500 in the shop that the owner described as ‘haunted.’ The radio would change stations on its own, the dome light would stay on, and the power locks had a mind of their own. He’d already replaced the battery and checked grounds with no luck. After connecting our scanner, we saw a dozen communication error codes all pointing back to the BCM. Instead of a complex wiring nightmare, the fix was simple: we installed a VIN-programmed BCM. In under 10 minutes, all the ghostly electrical issues were gone, and the truck was back to being a reliable workhorse.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic HVAC controls and blower motor function.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ An illuminated airbag light, often with diagnostic trouble codes like B1001.
- ✔ Multiple, unrelated electrical system error codes stored in the vehicle’s memory.

Installation & Post-Install Notes
Installation is straightforward. On the Savana and Express vans, the BCM is typically located in the center dash area. For most trucks and SUVs, it’s found under the steering column. Always disconnect the battery before swapping the module. While our VIN programming handles the heavy lifting, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. Additionally, a Brake Pedal Position Relearn may be needed. Best of all, there is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the HVAC system.
Do I need to have this module programmed by a dealer?
No. This BCM comes pre-programmed to your vehicle’s VIN. This makes the installation plug-and-play, saving you a trip to the dealership and additional programming fees.
Is this BCM difficult to install?
For most DIYers, the installation is simple and can take as little as 5-10 minutes. It involves locating the old module (usually under the dash), disconnecting the battery, and swapping the units.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, the vehicle may require an ‘SDM Primary Key Relearn’ procedure. This syncs the new BCM with the airbag system and must be performed with a compatible professional-grade diagnostic tool.
Will this fit vehicles other than a 2004-2007 Savana 3500 Van?
Yes, this BCM is compatible with a wide range of 2002-2007 GM vehicles, including the Chevrolet Silverado, Suburban, Tahoe, GMC Sierra, Yukon, Cadillac Escalade, and Hummer H2. Please verify the part number for your specific vehicle.
