Is Your GM Truck or Van Plagued with Electrical Gremlins?
If your 2004-2007 Chevrolet Express, Silverado, or other GM vehicle is experiencing bizarre electrical issues like flickering lights, unresponsive power windows, a dead HVAC blower, or a persistent airbag warning light, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let a faulty module sideline your vehicle. This OEM-quality replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2005 GMC Sierra in the shop that was driving the owner crazy. The radio would cut out randomly, the dome lights wouldn’t work, and the security light would flash, sometimes preventing the truck from starting. After checking grounds and fuses, we traced the problem to an internal failure in the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of these VIN-programmed units. The entire swap took less than 10 minutes, and every single electrical issue was resolved instantly. The customer was back on the road the same day, problem solved.
Identifying a Failing 2004-2007 Express BCM
A failing Body Control Module can manifest in numerous ways, often mimicking other problems. This module is the solution if you’re experiencing multiple electronic accessory failures.

Simple Installation and Post-Install Notes
Installation is straightforward for DIYers and professionals alike. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the vehicle’s battery, remove the old module, plug in the new one, and reconnect the battery. In most cases, that’s all it takes.
Important: In some vehicles, additional steps may be required after installation. If the airbag warning light illuminates, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. A brake pedal position sensor relearn may also be necessary on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific instructions.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, door locks, lighting, wipers, and the security system.
Is this module difficult to install?
No, the physical installation is very simple and typically takes just a few minutes. It involves unplugging the old module and plugging in the new one. No special tools are required for the swap itself.
Do I need to take my vehicle to the dealer after installing this?
No. This module comes pre-programmed to your vehicle’s VIN, so you can skip the expensive trip to the dealership for programming. It’s designed to be a plug-and-play solution.
What happens if my airbag light comes on after installation?
If the airbag light appears, it means the new BCM needs to be synchronized with the airbag system’s SDM module. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
How do I know for sure if my BCM is failing?
Common symptoms include multiple, unrelated electrical failures (e.g., windows and radio stop working at the same time), security system malfunctions, intermittent HVAC operation, and specific diagnostic trouble codes pointing to the BCM.
Will this fit my 2006 GMC Sierra even though the title mentions an Express Van?
Yes, this BCM fits a very wide range of GM trucks and SUVs from this era, including the 2006 GMC Sierra. We use a primary fitment in the title for clarity, but please check the full fitment list or your original part number to confirm.
