Restore Full Functionality to Your GM Van or Truck
If you’re battling bizarre electrical problems in your work van or truck—like flickering lights, a dead climate control system, or power windows with a mind of their own—you’ve likely met the culprit: a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and security features, its failure can cause a cascade of frustrating issues. This OEM-quality replacement, part number 15137393, is the definitive solution for your 2004-2007 Savana 1500 BCM and a wide range of other GM vehicles. Best of all, it arrives fully programmed to your vehicle’s VIN, eliminating the need for an expensive trip to the dealership.
From the Diagnostic Bay: The Case of the Contractor’s Van
I remember a contractor bringing in his ’06 Savana 2500. The complaint was intermittent: some days the radio wouldn’t work, other days the interior lights would stay on, draining the battery. He’d already replaced the battery and checked fuses. After hooking up my scanner, I saw a dozen communication codes pointing nowhere specific. This is a classic BCM failure sign. These modules often fail internally, causing unpredictable data corruption on the network. We installed a VIN-programmed BCM, and every single issue vanished. It’s a fix I’ve performed hundreds of times on these GM platforms; it turns a complex electrical mystery into a simple, reliable repair.
Is Your Savana Van Showing These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ The HVAC blower motor works intermittently or not at all.
- ✔ Power door locks or windows operate erratically or have failed completely.
- ✔ The security system triggers randomly or causes a no-start condition.
- ✔ An airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ Your scanner shows multiple communication or body-related diagnostic trouble codes.
Your 5-Minute Path to a Reliable Fix
One of the best features of this module is its simple, plug-and-play installation. No complex wiring, no special tools needed. For a 2004-2007 Savana 1500 BCM, the module is located in the center of the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and help reset system memory.
- Locate the Module: On Savana and Express vans, the BCM is typically found in the center dash area. On trucks and SUVs, it’s usually under the driver’s side dash, near the steering column.
- Swap the Part: Carefully unplug the wiring harness connectors from the old BCM and remove it. Secure the new module in place and firmly reconnect the harnesses.
- Power Up: Reconnect the battery terminal. Start the vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, an airbag light may persist. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure. Similarly, a brake pedal position relearn might be needed on certain models. Always consult a factory service manual for vehicle-specific procedures.

Frequently Asked Questions
What does VIN programming mean for me?
It means this module is a true plug-and-play part. We program it with your vehicle’s specific VIN before shipping, so it communicates perfectly with your van’s other systems right out of the box. This allows you to skip the time and expense of dealership programming.
Is this a difficult part for a DIYer to install?
Not at all. For most people, this is a 5-10 minute job. The BCM is typically easy to access in the center dash of a Savana van, requiring only basic hand tools to swap out.
Do I need to return my old BCM? (Core Charge)
No. We do not require a core return for this part. You can keep your old module without any extra charges or hassle.
Will this fix my airbag light?
If the airbag light is on due to a BCM communication error (like DTC B1001), this module will resolve the root cause. However, you may still need a professional scan tool to perform a quick “SDM Key Setup” to sync the new BCM with the airbag system and clear the light.
