If your 2013-2019 Savana 2500 Van is acting possessed with strange electrical issues, you’ve likely come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable workhorse into a frustrating puzzle. From power windows with a mind of their own to a security light that won’t turn off, the BCM is the central command for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; for a work van, it’s downtime that costs you money.
This is the definitive solution. We offer a genuine GM Body Control Module, part number 22915542, that arrives at your door pre-programmed to your van’s specific Vehicle Identification Number (VIN). Simply provide us with your VIN after purchase, and our experts will flash the module with the latest factory software from GM. This critical step means you can bypass the expensive and time-consuming trip to a dealership for programming. You get a reliable part that’s ready for installation, getting your Savana back in service faster.
From the Diagnostic Bay: The Ghost in the Work Van
I remember a plumbing contractor bringing in his 2016 Savana 2500. The complaint was a mess of intermittent problems: the radio would shut off randomly, the dome light would flicker, and sometimes the power door locks wouldn’t respond. He’d already replaced the battery and checked the grounds. After connecting my scan tool, I saw a slew of U-codes (communication errors), all pointing to the BCM. Instead of a costly dealer visit, we installed a VIN-programmed module just like this one. The install took less than an hour, and all the electrical gremlins were gone. He was back on the road to his next job that same afternoon, a testament to how the right part can save a business valuable time.
Common Signs Your Savana’s BCM is Failing
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security or anti-theft light stays illuminated, potentially causing a no-start condition.
- ✔ Wipers or horn activating unexpectedly or not working when needed.
- ✔ False warnings on the instrument cluster (e.g., “Door Ajar”).
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
Your Straightforward BCM Installation Guide
Installing your new BCM is a manageable job for a DIYer with basic tools. In the Savana and Express vans, the BCM is typically located in the center dash area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting work.
- Access the Module: You will need to remove trim panels around the center dash or radio to gain access to the BCM. Its exact position can be confirmed with a service manual, but it’s generally mounted in a junction block.
- Swap the BCM: Carefully disconnect the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Unclip or unbolt the old module and remove it.
- Install the New Module: Seat the new, pre-programmed BCM in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, wipers, etc.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Always consult a factory service manual or a qualified technician if you are unsure about any step. Procedures can vary slightly by year and specific options.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s comfort and convenience features. It controls functions that aren’t related to the engine, like power windows, lights, door locks, the security system, and wipers.
Is this installation truly plug-and-play?
Because we program the module to your VIN before shipping, it is as close to plug-and-play as possible. It eliminates the need for dealer programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor after installation.
Do I have to return my old BCM?
No. There is no core charge for this part. You can keep your original module, which saves you the time and expense of shipping a core back.
How do I give you my VIN for programming?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information to ensure correct programming.
What if my airbag light is on after I install the new BCM?
This can happen. It means the BCM needs to be electronically synced with the airbag module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. A local repair shop can typically perform this service for you.
