If you’re dealing with bizarre electrical issues in your 2013-2021 Chevrolet Express 3500 Van, you know how frustrating it can be. One minute the power locks work, the next they don’t. The dome light might stay on, or your dash could light up with random warnings. As a technician with over two decades of experience, I’ve seen these exact problems hundreds of times, and they almost always point to a failing Body Control Module (BCM). This isn’t just an annoyance; for a work vehicle like the Express Van, downtime means lost income. The BCM is the central hub for your van’s body electronics, and when it goes bad, it creates chaos.
We offer a straightforward, reliable solution. This is a genuine OEM Body Control Module, part number 22915542 (also interchangeable with 22820314), that comes fully programmed to your van’s specific Vehicle Identification Number (VIN). This means you skip the expensive trip to the dealership for programming. Simply provide us with your VIN after purchase, and we’ll handle the software flashing with the latest GM updates before it even ships. It’s the most efficient way to restore your van’s functionality and get back on the road.
Case Study: A Tricky Diagnosis
A local contractor brought in his 2016 Express 3500 with a list of complaints that sounded like a poltergeist had taken up residence. The radio would turn on by itself, the wipers would activate randomly, and the security light was always on, sometimes preventing the van from starting. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of U-codes (communication errors) pointing to the BCM. A failing BCM can flood the vehicle’s data network with bad information, causing other modules to act erratically. We installed a pre-programmed BCM, and every single issue vanished. It’s a classic example of how one central component can cause a cascade of seemingly unrelated problems.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing no-start conditions (Security light on).
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0100, U0140, or other U-series codes.
- ✔ Parasitic battery drain that you can’t trace to any other source.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: In most Express and Savana vans, the BCM is located in the center dash area, often behind the lower instrument panel or glove box. You may need to remove some trim panels 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, unbolt or unclip the old module and remove it from the vehicle.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- ✔ Perform Post-Install Procedures: As noted below, some vehicles may require additional steps. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key’ procedure. A Brake Pedal Position relearn might also be necessary for proper traction control function.
Important Note on Post-Installation Steps: While this module is programmed to your VIN, certain security and safety systems may require a final handshake with the new BCM. If the airbag light appears, the ‘Setup SDM Primary Key in BCM’ procedure is necessary. Additionally, a Brake Pedal Position Relearn might be required. These procedures need a bi-directional scan tool and are typically performed by a professional mechanic. Always consult a factory service manual for your specific vehicle.

Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you a trip to the dealer.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship the part until we receive this information.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
What if my airbag light is on after installation?
This can happen. It means the new BCM needs to be synced with the airbag system’s SDM. A professional technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
What is a BCM?
The Body Control Module (BCM) is a computer in your vehicle that controls electronic accessories like power windows, lights, door locks, the security system, and more. It acts as a central hub for these functions.
