Restore Full Functionality to Your GM Van or Truck
Are you chasing down bizarre electrical problems in your Chevy Express or GMC Savana? One day the power locks don’t work, the next the A/C blower quits, and the airbag light is on for no apparent reason. As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times, and they almost always point to a failing Body Control Module (BCM). This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. This BCM, compatible with part number 15137395, is the central command center for your vehicle’s body electronics, and when it fails, chaos ensues.
Our professional cloning service makes this repair straightforward. You send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. The result is a true plug-and-play module that requires no expensive trip to the dealership for programming. This is the most efficient way to get a reliable fix for your 2004-2007 Express 1500 BCM and get your work van or family hauler back in service.
A Technician’s Notebook: The Commercial Van Conundrum
I remember a 2006 Express 2500 from a local plumbing company that came into the shop. The complaint was ‘the truck is possessed.’ The driver reported the radio would change stations on its own, the dome light would flicker, and sometimes the van wouldn’t start, displaying a ‘Service Security System’ message. They had already replaced the battery and checked the grounds. After hooking up my scan tool, I saw a dozen communication codes pointing toward the BCM. A failing BCM in a work van means lost time and lost money. We used a cloned BCM to solve the problem. By transferring the data, we ensured all the specific options for their commercial tradesman package worked perfectly upon installation. The van was back on the road making money that same afternoon.
Is Your GM Vehicle Showing These BCM Failure Signs?
- ✔ The HVAC blower motor works intermittently or not at all.
- ✔ Power windows, door locks, or interior/exterior lights behave erratically.
- ✔ The anti-theft or security system prevents the engine from starting.
- ✔ An airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Communication is lost with other modules, triggering various U-codes (e.g., U0140).
- ✔ The instrument cluster displays strange warnings or gauges act erratically.
Your Step-by-Step BCM Installation Guide
Installing your cloned 2004-2007 Express 1500 BCM is a simple process that most DIYers can complete in minutes. For Express and Savana vans, the BCM is typically located in the center of the dash.
- Step 1: Disconnect the Battery. Always begin by disconnecting the negative battery terminal to prevent electrical shorts and help reset the vehicle’s systems.
- Step 2: Locate the BCM. On most Express/Savana vans, you’ll find it behind a panel in the center dash area. On trucks and SUVs, it’s usually under the steering column.
- Step 3: Unplug and Remove. Carefully disconnect the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unclip or unbolt the old module and remove it.
- Step 4: Install the New Module. Seat the replacement BCM in the mounting bracket and securely reconnect all electrical harnesses. You’ll hear a click as they lock in place.
- Step 5: Reconnect and Test. Reconnect the negative battery terminal. Start the vehicle and test all body functions: lights, locks, windows, wipers, and HVAC to confirm the repair is successful.
Post-Installation Note: In some cases, a procedure like an ‘SDM Key Setup’ or ‘Brake Pedal Position Relearn’ may be needed if you see a related warning light. This requires a bi-directional scan tool. However, our cloning service minimizes the need for these extra steps.

Frequently Asked Questions about the 2004-2007 Express 1500 BCM
How does the cloning service work?
After you place your order, you’ll receive instructions to ship your original BCM to us. We extract the vehicle-specific data and flash it onto your replacement module. This makes it a plug-and-play part, saving you from dealer programming fees. We then ship both your original and the newly programmed module back to you.
Do I need to do any programming myself?
No. Our cloning service handles all the necessary programming. The module will arrive ready for installation, already configured to your vehicle’s VIN and specific options.
What if my old BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or water), data recovery may not be possible. Please contact us to discuss your specific situation.
Why is my airbag light still on after installation?
This can happen if the BCM and the SDM (airbag module) lose their synchronization. A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to re-establish communication and turn off the light.
Is there a core charge for this part?
No. We require your original module for the cloning service, but there is no separate core charge. We always return your original part along with the programmed replacement.
