Restore Full Functionality to Your GM Vehicle
If your 2008-2012 Savana 2500 is plagued by bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating problems, from flickering lights and malfunctioning power windows to intermittent starting and false security alarms. Don’t let these electrical gremlins keep your work van or family hauler off the road. This replacement Body Control Module is the reliable, straightforward solution you need.

Unlike a generic part from a big-box store, each module we ship is professionally programmed with the latest GM software updates specifically for your vehicle. Simply provide us with your VIN during checkout, and we handle the complex flashing process. This means when the part arrives, it’s ready for installation, saving you a costly trip to the dealership and hours of diagnostic headaches. Get your vehicle’s essential systems—like lighting, security, and power accessories—working like new again with a dependable, VIN-matched Savana 2500 Body Control Module.
Case Study: A Tricky Diagnosis
A customer’s 2011 Savana 2500 work van came into the shop last month with a list of strange symptoms. The dome lights would stay on, the power locks worked only half the time, and the radio would randomly shut off. The driver was convinced he had multiple wiring shorts. After checking the main power and ground connections, which were solid, my diagnostic scanner pointed to a communication breakdown with the BCM. These modules are notorious for failing due to heat cycles and internal solder joint cracks. We installed one of our pre-programmed units, and within an hour, every single electrical issue was resolved. It’s a classic case where replacing one central component, the Savana 2500 Body Control Module, saves hours of chasing phantom electrical problems.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system engaging randomly or the horn honking unexpectedly.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Warning lights on the dash, particularly for the airbag or security system.
- ✔ Problems with the radio, climate control, or other dash-mounted accessories.
A Straightforward Guide to Installation
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most Savana and Express vans, the BCM is located behind the center dash panel. You may need to remove trim pieces to gain access.
- Disconnect and Remove: Carefully unplug the wiring harness connectors from the old module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM and remove it from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all wiring harnesses, ensuring each plug clicks firmly into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Perform Relearn Procedures: Start the vehicle. You will need to perform the necessary post-installation procedures as outlined below to ensure full system functionality.
Important Post-Installation Steps
After installing your new Savana 2500 Body Control Module, a few final steps are required to sync the new part with your vehicle’s other systems. These procedures are critical for safety and performance.
- Airbag System Reset: To clear the airbag warning light, a technician must perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible high-level diagnostic scan tool. This ensures the airbag system is properly communicating with the new BCM.
- Brake Pedal Position Sensor Relearn: Some models may require a recalibration of the brake pedal position sensor. This is essential for the proper function of the anti-lock brake and stability control systems.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation, saving you time and money.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information.
Is this a simple plug-and-play installation?
The physical installation is plug-and-play. However, as with any BCM replacement, post-installation procedures like an airbag system reset and potentially a brake pedal relearn are required using a professional scan tool for full functionality.
What if my original part number is not 95151084?
This module replaces dozens of older GM part numbers. Please check the comprehensive list in our description. If your number is on that list, this part will work for you.
Will this fix my power window and lock problems?
In most cases, yes. The BCM directly controls these functions, and its failure is a very common cause of these specific symptoms in GM vehicles of this era.
