Restore Full Functionality to Your GM Van or Truck
Are you dealing with baffling electrical issues in your 2004-2007 Chevrolet Express 2500? One moment the power windows work, the next they don’t. Maybe your HVAC controls have a mind of their own, or you’re staring at a persistent airbag light. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). This module is the central command for your vehicle’s body electronics, and when it goes, it can cause a cascade of frustrating problems. This OEM-quality replacement, part number 10367690, is the reliable, straightforward solution you need.
A Technician’s Notebook: The Contractor’s Van
A customer brought in his 2006 Express 2500 work van last month with a list of strange symptoms. The dome light would stay on, the power door locks were intermittent, and twice it had left him stranded with a no-start condition. He suspected a bad ground, which is a common culprit. After spending an hour checking main grounds and finding nothing, we hooked up the scanner. It was flooded with communication and body-related DTCs, including a B1001. In my 20+ years of experience, a flood of seemingly unrelated electrical codes almost always points to the BCM. We swapped in a pre-programmed module, and every single issue was resolved instantly. This is why a quality Express 2500 Body Control Module is the go-to fix for these exact scenarios.
Is Your Vehicle Showing These Common BCM Failure Symptoms?
- ✔ Intermittent or completely dead HVAC controls and blower fan.
- ✔ Power windows, door locks, or exterior lights not working correctly.
- ✔ An active airbag warning light on the dash, often with a B1001 code.
- ✔ Security system faults, leading to a no-start or crank-no-start situation.
- ✔ A variety of seemingly random diagnostic trouble codes (DTCs) related to body systems.
Why Choose a VIN-Programmed Module?
The single biggest advantage of this Express 2500 Body Control Module is that it arrives at your door pre-programmed for your specific vehicle. We use your VIN to load the latest GM software, ensuring it communicates perfectly with your van’s other systems right out of the box. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. It’s built to strict OEM standards and backed by a one-year warranty, giving you peace of mind that you’re installing a durable, reliable part.
A Straightforward Guide to Installation
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electrical work.
- Locate the BCM: In most Express and Savana vans, the BCM is located in the center of the dash. In trucks and SUVs, it’s typically found under the steering column.
- Remove the Old Module: Carefully unplug the electrical connectors and remove any mounting screws or clips holding the old BCM in place.
- Install the New BCM: Seat the new module in the same position, reconnect the electrical harnesses securely, and fasten it in place.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
- Post-Installation Checks: For some vehicles, you may need a capable scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the airbag light. A brake pedal position recalibration may also be necessary.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It controls non-engine related functions like your interior and exterior lights, power windows and locks, wipers, security system, and HVAC blower controls.
Is this part truly plug-and-play?
Yes. Because we program it to your vehicle’s VIN before shipping, it is ready for installation without needing any additional programming from a dealership. This makes it a perfect solution for both DIYers and professional shops.
Do I need special tools for the installation?
Basic hand tools are all that’s required for the physical installation, which typically takes just a few minutes. However, to clear a persistent airbag light after installation, a professional-grade scan tool capable of performing the ‘Setup SDM Primary Key’ function is required.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of a B1001 code. Replacing the module will likely resolve the root cause, but you will still need to perform the SDM key relearn procedure with a scan tool to turn off the warning light.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without the hassle of needing to return it.
