Restore Full Functionality to Your GM Van or Truck
Are you chasing down frustrating electrical issues in your 2004-2007 Express 3500 Van? When your power windows, door locks, or HVAC system start acting erratically, the Body Control Module (BCM) is often the culprit. As the central command for your vehicle’s body electronics, a failing BCM can cause a cascade of problems that are difficult to diagnose. This replacement Body Control Module, equivalent to GM part number 10367690, is the definitive solution. We pre-program it to your vehicle’s specific VIN, ensuring it works right out of the box with no expensive dealership programming required.
Case Study: A Tricky Diagnosis
I remember a 2006 Express 3500 work van that came into my shop. The owner was at his wit’s end. The radio would turn on and off by itself, the dome lights wouldn’t work, and sometimes the van wouldn’t start, showing a security light. He’d already replaced the battery and checked the fuses. After connecting my scanner, I saw a handful of communication codes (U-codes) pointing to the BCM. These modules often fail internally from heat cycles and vibrations, causing these exact kinds of ‘ghost’ problems. Installing a VIN-programmed BCM like this one resolved all his issues in under 15 minutes, getting his work van back on the road and making money.
Is Your Express Van Showing These Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls failing to operate correctly.
- ✔ The security system light is on, preventing the vehicle from starting.
- ✔ An airbag warning light on the dash, sometimes with a B1001 diagnostic trouble code.
- ✔ Wipers that won’t turn on, or won’t turn off.
- ✔ A cluster of seemingly unrelated electrical problems.
A Straightforward Guide to Installation
One of the best features of this module is its simple, DIY-friendly installation. Since we handle the programming, you can skip the dealership visit. For the 2004-2007 Express 3500 BCM, you’ll typically find it in the center of the dash.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On Express and Savana vans, the BCM is located behind the lower center dash trim panel. On most trucks and SUVs, it’s under the driver’s side of the dashboard, near the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unclip or unbolt the old module and remove it.
- Install the New Module: Seat the new, pre-programmed BCM in place and securely plug in all the connectors. You’ll hear a click as they lock.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all body functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, you may need a capable scanner for a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on. This syncs the new BCM with the airbag system. A brake pedal position relearn might also be needed on certain models.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for plug-and-play installation, saving you time and the high cost of dealership programming.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without needing to send it back, simplifying the process for you.
What tools do I need for installation?
For most applications, you’ll only need basic hand tools like a socket wrench to disconnect the battery and possibly a trim removal tool to access the BCM behind the dash panel. No special electronic tools are required for the physical installation.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (like DTC B1001), this part will resolve the root cause. However, after installation, you may need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
What if my vehicle isn’t a van?
This BCM fits a wide range of GM trucks and SUVs from 2002-2007, including the Silverado, Sierra, Tahoe, and Suburban. Please check the detailed fitment list to confirm it matches your specific model and configuration. The primary difference is often the mounting location.
