Fix Your Van’s Electrical Issues with a Plug-and-Play BCM
If your 2004-2007 GMC Savana 2500 Van is plagued by baffling electrical problems, a failing Body Control Module (BCM) is the likely culprit. As the central command for your van’s comfort and security features, a faulty BCM can make your workday incredibly frustrating. This replacement module, part number 10383536, is the reliable, long-term solution you need. With our expert cloning service, we transfer your original module’s data—including VIN, mileage, and key information—directly to this unit. The result is a true plug-and-play part that requires no expensive trip to the dealership for programming.
From the Diagnostic Bay
I remember a fleet manager bringing in a 2006 Savana 2500 work van that was driving his crew crazy. The radio would turn on by itself, the power locks worked only half the time, and the airbag light was on, flashing a DTC B1001. They had already replaced the battery and checked grounds, but the gremlins persisted. After a quick scan, it was clear the BCM was failing internally. Instead of a costly new module and dealer programming, we used our cloning service. We transferred the data from his old, faulty BCM to our replacement unit. He had the van back on the road the same day, fully functional, saving him hundreds in parts and labor. This is the exact, hassle-free solution we offer you.
Is Your Savana Exhibiting These Electrical Gremlins?
A failing BCM doesn’t always cause a total shutdown. More often, it presents as a set of strange, intermittent issues. Here’s what to look for:
- ✔ Power windows or door locks not working or operating erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ HVAC and climate control functions are unresponsive or blower motor is intermittent.
- ✔ The security system acts up, preventing the van from starting (no-start condition).
- ✔ An active airbag warning light on the dash, often with a B1001 trouble code.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) stored in the system.
A Straightforward Guide to Installation
For the GMC Savana and Chevrolet Express vans, this is one of the easier module swaps you can do. You don’t need a vehicle lift or complex tools.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In the 2004-2007 Savana/Express vans, the BCM is located in the center of the dashboard, typically accessible after removing a lower dash panel.
- Disconnect and Remove: Carefully unclip the wiring harness connectors from the old module. They have locking tabs, so don’t force them. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely reconnect all wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the battery terminal. Start the van and test all body functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Important Post-Installation Notes
Our cloning service makes this repair as simple as possible, but in some GM vehicles, a couple of quick sync procedures may be needed. If your airbag light remains on, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. Some models may also require a Brake Pedal Position sensor relearn. These are not always necessary but are important to be aware of for a complete repair.

Frequently Asked Questions
How does the cloning service work?
After you place your order, you’ll ship your original BCM to us. Our technicians will extract the unique data from your module and flash it onto the replacement unit. We then ship both your original module and the ready-to-install replacement back to you.
Do I need to get my keys reprogrammed?
No. Because we clone your original module’s data, the new BCM will recognize your existing keys, saving you a significant amount of time and money.
What if my original module is lost or completely destroyed?
In cases where the original module cannot be read, we can often program a replacement using your vehicle’s VIN. However, this may require additional programming for keys or other systems upon installation. Please contact us first if you cannot provide your original BCM.
Is there a core charge for this part?
No. We require your original module for the cloning service, but we always return it to you along with the replacement part. There are no core charges or fees.
