Restore Your Van’s Electrical Functions and Reliability
If you’re dealing with bizarre electrical issues in your 2003-2007 Savana 2500 Van—like power windows that won’t roll down, interior lights with a mind of their own, or a security system that randomly prevents your van from starting—you’re likely facing a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a dependable workhorse into a source of constant frustration. This isn’t just an inconvenience; it’s a reliability issue that can cost you time and money. This module is the central command for your vehicle’s body electronics, and when it fails, chaos ensues.
We offer a straightforward, reliable solution. This replacement Body Control Module, part number 15136224, arrives at your door programmed to your vehicle’s specific VIN. We handle the complex part by flashing it with the latest GM software updates before we ship. This means you can bypass the expensive trip to the dealership for programming, saving you hundreds of dollars and significant downtime. Simply provide your VIN at checkout, and we’ll deliver a module that’s ready for installation.
A Technician’s Notebook: The Ghost in the Work Van
I remember a 2006 Savana 2500 that came into my shop. The owner, a plumber, was at his wit’s end. The dome lights would flicker, the radio would cut out, and sometimes the van wouldn’t start, showing a security light. He’d already replaced the battery and checked the grounds. After connecting my scan tool, I saw a flurry of U-codes (communication errors) pointing to the BCM. A quick check under the center dash revealed the problem: a leaky windshield had allowed water to drip directly onto the BCM, causing internal corrosion. We replaced it with a VIN-programmed unit like this one, and all the ghostly electrical problems vanished instantly. It’s a common failure point on these work vans.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (e.g., dome lights staying on, headlights not working).
- ✔ The security system light is on, and the vehicle won’t start (anti-theft system issues).
- ✔ Warning lights for ABS, Airbag, or Traction Control appearing on the dash without a clear cause.
- ✔ Communication error codes (U-codes) when scanned with a diagnostic tool.
- ✔ Inconsistent horn or radio operation.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down.
- ✔ Locate the BCM: On Savana and Express vans, the BCM is typically located in the center of the dashboard, often behind the radio or climate control panel. You will need to remove some dash trim to access it.
- ✔ 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 module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test functions like power windows, locks, and lights.
- ✔ Perform Relearns (If Needed): Start the vehicle. If you see an airbag light or notice brake light issues, you may need to perform the post-installation procedures outlined below with a compatible scan tool.
Important Post-Installation Information
While our VIN programming handles the most critical step, some GM vehicles require a final handshake between modules after installation. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag light is illuminated after installation, a scan tool procedure called “Setup SDM Primary Key in BCM” is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.
Disclaimer: These procedures may require a bi-directional scan tool. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to be installed, saving you a trip to the dealership.
What is a BCM and what does it do?
The BCM, or Body Control Module, is a computer that controls your vehicle’s non-engine-related electronics. This includes power windows, locks, lights, the horn, the security system, and more.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, your insurance card, or on a small plate on the driver’s side of the dashboard, visible through the windshield.
What if my airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag module. A mechanic with a professional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
Is this a new or used part?
This is a high-quality, inspected, and tested recycled OEM part, which we then program with the latest software for your specific vehicle. This ensures OEM fit and function without the new-part price tag.
