Solve Your Van’s Electrical Headaches
If your 2004-2007 Chevrolet Express 1500 Van is suddenly possessed by electrical gremlins—the air conditioning is acting up, the power locks have a mind of their own, or you’re seeing a persistent airbag light—you’re likely dealing with a failing Body Control Module (BCM). As the central command for your van’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable issues. Instead of spending a fortune at the dealership for a new module and programming, our Cloning Service offers a simple, cost-effective, and reliable solution.
We transfer the critical data from your original module directly to this quality replacement unit. This means the replacement BCM arrives at your door ready for plug-and-play installation, with no need for expensive dealer tools or software. This service is the perfect fix for both seasoned mechanics and DIYers looking to restore their vehicle’s functionality quickly and correctly. This service is for part number 15136877 and is interchangeable with several other GM part numbers.
A Technician’s Notebook
I had a 2006 Express work van in my bay last month that was a diagnostic nightmare for the owner. The radio would turn on and off, the dome light would flicker, and occasionally the van wouldn’t start, showing a security light. He’d already replaced the battery and checked grounds. After connecting my scan tool, I saw multiple communication loss codes with the BCM. These intermittent data-line issues are a classic sign of internal BCM failure. We performed our cloning service, and the replacement 2004-2007 Express 1500 BCM solved every single issue. It’s a fix I’ve performed hundreds of times on these GM platforms.
Key Features of Our Cloning Service
By choosing our cloning service for your 2004-2007 Express 1500 BCM, you get a part that is perfectly matched to your vehicle’s specific configuration. This process preserves all original settings, including key fob data and factory options, ensuring a seamless transition and restoring your van to its proper operational state.
A Straightforward Guide to BCM Installation
- ✔ Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the Express Van, the Body Control Module is typically found in the center dash area. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove the bolts or clips holding the module in place.
- ✔ Install the New Module: Seat the new, cloned BCM into the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- ✔ Reconnect and Test: Reattach the negative battery terminal. Start the vehicle and test all body functions—lights, wipers, windows, door locks, and HVAC—to confirm the repair was successful.
Is Your Van Exhibiting These BCM Failure Signs?
- ✔ Intermittent or non-functional HVAC controls, including the blower motor.
- ✔ Power windows, door locks, or interior/exterior lights behaving erratically or not working at all.
- ✔ An illuminated airbag light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Vehicle security system issues, including a no-start condition where the engine cranks but won’t fire.
- ✔ Unexplained battery drain or strange electrical behavior that seems to have no direct cause.
- ✔ Communication loss codes (U-codes) when scanned with a professional diagnostic tool.
Post-Installation Checks
In most cases, this is a plug-and-play repair. However, on some vehicles, additional steps may be required. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. Your original module will be returned to you with the cloned unit; we do not require a core.

Frequently Asked Questions
What is a BCM cloning service?
Cloning is a process where we read the essential vehicle-specific data (like VIN, mileage, and key information) from your original BCM and write it onto the replacement module. This makes the new part a perfect digital copy, eliminating the need for dealership programming.
What if my original BCM is too damaged to be read?
In most cases, even with significant internal failure, we can still extract the necessary data. If your module has severe physical or water damage, please contact us first to discuss options. We’ll do our best to find a solution.
Do I need to send my original module to you?
Yes. For the cloning service to work, we need your original BCM. After you place your order, we will provide instructions for shipping it to our facility. We will return your original module with your newly programmed replacement.
Will I need to perform any relearn procedures after installation?
Typically, no. The goal of cloning is a plug-and-play result. However, in some instances, such as if the airbag light stays on, an ‘SDM Key Setup’ may be needed with a high-level scan tool. This is a simple procedure for most professional shops.
What is the warranty on this BCM?
This Body Control Module comes with a one-year warranty, covering any defects in the part or the programming service, giving you peace of mind with your repair.
