Fix Your GM Van’s Electrical Headaches for Good

As a technician with two decades of experience, I’ve seen countless work vans like the 2004-2007 Chevrolet Express 3500 sidelined by baffling electrical problems. One day the power locks work, the next they don’t. The A/C blower motor has a mind of its own, and you’re chasing phantom electrical draws that drain the battery. More often than not, the culprit is a failing Body Control Module (BCM). This isn’t just an inconvenience; for a work vehicle, downtime means lost money. This replacement BCM, part number 10367690, is the definitive solution, arriving pre-programmed to your van’s specific VIN for a true plug-and-play repair.

Is Your GM Vehicle Showing These Symptoms?

• ✔ Strange and unpredictable electrical issues, like wipers or lights turning on by themselves.
• ✔ Power windows, door locks, or mirrors that work intermittently or not at all.
• ✔ HVAC system problems, such as a non-working blower fan or climate controls that are unresponsive.
• ✔ An active security light on the dash, or a no-start condition where the engine cranks but won’t fire.
• ✔ The airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
• ✔ A dashboard lit up with various warning lights and communication error codes when scanned.

A Straightforward Guide to BCM Installation

One of the best features of this module is its simple installation. You don’t need to be a master mechanic to get your van back in service. For most models, the entire process takes less than 10 minutes.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents shorts and helps reset the vehicle’s electronic systems.
2. Locate the BCM: On the 2004-2007 Express 3500 Van, the BCM is typically found in the center of the dash. On other GM trucks and SUVs, it’s usually under the driver’s side dash, near the steering column.
3. Swap the Module: Carefully unplug the wiring harness connectors from your old BCM. They have release tabs that need to be pressed. Remove any retaining bolts or clips holding the old module, then install the new one in its place.
4. Reconnect & Test: Plug the wiring harnesses securely into your new BCM. Reconnect the battery terminal. Start the vehicle and test all body functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
5. Post-Installation Checks: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems. This is a simple software function, not a defect in the part.
