Fix Your Van’s Electrical Issues with Our BCM Cloning Service
Are you battling strange electrical problems in your 2004-2007 Chevrolet Express 3500 Van? A faulty Body Control Module (BCM) is often the culprit behind issues like flickering lights, malfunctioning power locks, or an unresponsive HVAC system. This is more than an annoyance; for a work van, it’s downtime that costs you money. This replacement BCM, part number 15136877, is the definitive solution, offered with our expert cloning service to get your vehicle back in service with minimal hassle.
Unlike off-the-shelf modules that require expensive dealership programming, our cloning service makes this a plug-and-play repair. You simply send us your original BCM, and we transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement unit. When you receive it back, it’s a direct swap. This process ensures seamless integration with your van’s existing electronic systems, like the ECU and security module, eliminating compatibility errors and the need for complex relearn procedures. This is the most reliable way to fix a failing 2004-2007 Express 3500 Van BCM without a trip to the dealer.
Case Study: A Technician’s Notebook
I had a 2006 Express 3500 work van come into my bay that was driving the owner crazy. The complaint was intermittent: the radio would cut out, the dome lights would flicker, and occasionally the power door locks wouldn’t work. They had already replaced the battery and checked the main grounds. After hooking up my scanner, I found a slew of U-codes (communication errors) pointing to the BCM. A quick tap test on the BCM under the dash confirmed it—the lights went haywire. A failing BCM can act like a bad ground, causing chaos across the entire vehicle network. We used a cloned module to preserve all the van’s commercial package settings, and it was back on the road making money the next day.
Is Your Express Van Showing These Electrical Faults?
A failing BCM can manifest in numerous ways. If your van is experiencing any of the following, it’s a strong indicator that your module needs attention. Diagnosing this correctly is the first step to a lasting repair for your 2004-2007 Express 3500 Van BCM.
- ✔ Intermittent or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ HVAC system problems, such as the blower motor not working or temperature controls failing.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ An airbag light that stays on, often with a B1001 diagnostic trouble code.
- ✔ A dashboard full of warning lights and communication error codes (U-codes).
A Straightforward Guide to Installation
This process is designed to be simple for any DIYer or professional technician. The key is our cloning service, which handles all the complex programming work for you. Here’s how it works:
- Step 1: Place your order and securely package your original BCM. We’ll provide shipping instructions.
- Step 2: Once we receive your module, our technicians will perform a full data transfer to the replacement unit.
- Step 3: We ship both your original module and the ready-to-install cloned BCM back to you.
- Step 4: Safety First: Before starting the physical swap, disconnect your van’s negative battery terminal to prevent electrical shorts.
- Step 5: Locate and Replace: The BCM in the Express Van is typically found in the center dash area. Carefully unplug the wire harness connectors from the old module and remove it. Install the cloned module in its place and reconnect the harnesses.
- Step 6: Final Steps: Reconnect the battery terminal. Start the vehicle to confirm that all functions are restored. In some cases, a post-install procedure like an Airbag System Sync may be needed if the airbag light appears.

How does the BCM cloning service work?
You purchase the service and send us your original Body Control Module. Our technicians extract the vehicle-specific data (VIN, security info, options) from your module and flash it onto the replacement unit. We then send both modules back to you. The replacement is then ready for plug-and-play installation with no further programming needed.
Will I need a dealership to program this module?
No. The entire point of our cloning service is to eliminate the need for dealership programming. Because we transfer the data from your original part, the new module is a perfect electronic match for your vehicle right out of the box.
What happens to my original BCM?
Your original module is always returned to you along with the newly programmed replacement. We do not keep customer cores, so you can keep it for your records or dispose of it as you see fit.
What if my airbag light is on after installation?
In some cases, the BCM and the Sensing and Diagnostic Module (SDM) for the airbag system may need to be re-synced. This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade scan tool.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a straightforward installation. The BCM is typically located in the center dash on Express vans and is accessible after removing a few trim panels. The main challenge is unplugging and replugging the connectors in a tight space. No special tools are required for the physical swap.
