Restore Your Van’s Electrical System with a Reliable, Pre-Programmed BCM
If you’re dealing with frustrating electrical issues in your 2008-2012 Savana 2500 Van—like interior lights that won’t turn off, power windows with a mind of their own, or a security light that prevents your engine from starting—you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it malfunctions, it can create a cascade of bizarre, hard-to-diagnose problems. This isn’t just an annoyance; it can take your work van off the road and impact your bottom line.
This replacement Body Control Module is the definitive solution. It arrives at your door pre-programmed to your vehicle’s specific VIN. This means you can skip the expensive trip to the dealership for programming. We handle the complex part for you: simply provide your VIN after purchase, and we’ll flash the module with the latest GM software updates, ensuring perfect integration and function right out of the box. Get your van’s essential features working reliably again.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Express van with an intermittent no-start and a flickering security light. He’d already replaced the ignition switch and checked the battery, but the problem persisted. On the scan tool, I saw multiple U-codes (communication errors) pointing to the BCM. These communication faults are a classic sign. The BCM wasn’t properly talking to the ignition security system or the powertrain module. We installed one of our pre-programmed BCMs, and the van fired up instantly. The electrical gremlins were gone. It’s a reminder that what looks like multiple separate problems often traces back to one faulty module.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, it’s a strong indicator that your Body Control Module needs replacement:
- ✔ Erratic or non-functional interior and exterior lights (dome lights, headlights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security or anti-theft system light is on, causing a no-start condition.
- ✔ The dashboard warning lights are flickering or staying on without reason.
- ✔ The horn sounds randomly or doesn’t work when pressed.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes (e.g., U0140, U0155).
- ✔ Wipers turning on by themselves or not working properly.
Your Straightforward BCM Installation Guide
Installing your new 2008-2012 Savana 2500 BCM is a manageable job for a DIYer or professional mechanic. Since we pre-program it, you eliminate the most difficult step.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: In most Savana and Express vans, the BCM is located behind the center of the dashboard, often accessible by removing lower dash panels. Consult a service manual for your specific model’s exact location.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the new, pre-programmed BCM in the same location and securely plug in all electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test all body functions: lights, locks, windows, wipers, etc.
- Post-Installation Checks: In some cases, additional steps may be needed. If your airbag light is on, an ‘Airbag System Sync’ may be required. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary for proper brake light and traction control function. These procedures typically require a professional-grade scan tool.

Frequently Asked Questions
Do I need to send my VIN number?
Yes. To ensure 100% correct functionality, we program this BCM using your vehicle’s VIN before we ship it. Please provide your 17-digit VIN during or after checkout.
Is this a plug-and-play part?
Yes, because we program it for you, it is designed to be plug-and-play. However, as noted, some vehicles may require a simple relearn procedure for the brake pedal position or airbag system, which may require a scan tool.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module.
Will this fix my security light issue?
In most cases, yes. A faulty BCM is a very common cause of security system problems and no-start conditions in these GM vehicles. Our programming ensures the security data matches your vehicle’s keys.
What if my original part number isn’t 25847589?
Please check the extensive list of compatible part numbers above. This module replaces many different original part numbers, so as long as your number is on that list, this part will work for you.
