Restore Full Functionality to Your GM Vehicle
Is your van or SUV plagued by bizarre electrical problems? Flickering lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable issues. This replacement Body Control Module, part number 95151084, is the reliable, straightforward solution to get your vehicle back in order without the exorbitant costs and scheduling hassles of a dealership visit.
A Technician’s Notebook: The Case of the Haunted Work Van
I remember a 2011 Express 1500 work van that came into my bay with a list of complaints that sounded like something out of a ghost story. The driver said the dome lights would randomly turn on while driving, the power locks would cycle on their own, and sometimes, the van just wouldn’t crank. A scan tool showed a slew of U-codes, indicating a loss of communication with various modules. Instead of chasing individual components, my experience pointed straight to the BCM. After swapping in a new module programmed to the van’s VIN, every single phantom issue vanished. It’s a common failure point, and a properly programmed module is the only true fix.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a failing BCM is the likely culprit. Replacing it can resolve numerous problems at once.
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light stays on, preventing the engine from starting.
- ✔ The horn sounds randomly or doesn’t work at all.
- ✔ Wipers operate intermittently or get stuck in one position.
- ✔ Multiple unrelated warning lights illuminated on the dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or U0164.
The Critical Advantage: VIN-Specific Programming
Ordering a BCM off the shelf won’t work. Modern vehicles require the BCM to be programmed specifically to their Vehicle Identification Number (VIN) to communicate with other onboard computers. We handle this critical step for you. Before we ship your part, our technicians will flash this module with the latest GM-certified software for your exact vehicle. This ensures it works correctly right out of the box, integrating seamlessly with your van’s existing systems. This is the same service a dealer performs, but without the extra appointment and labor fees. All you need to do is provide your VIN during checkout, and we’ll take care of the rest.
A Straightforward Guide to Installation
For the 2008-2012 Express 1500 Van, the BCM is typically located in the center of the dash. While professional installation is always an option, a confident DIYer can perform this replacement.
- 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: On the Express/Savana vans, you’ll generally find the BCM behind the lower center dash trim panel. Access may require removing a few trim pieces or the glove box.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Avoid pulling on the wires. Once disconnected, unbolt or unclip the old BCM and remove it.
- Install the New Module: Seat the new, pre-programmed BCM in the mounting location and secure it. Reconnect all electrical harnesses, ensuring each one clicks firmly into place.
- Final Steps: Reassemble your dash panels and reconnect the negative battery terminal. Start the vehicle to confirm that the primary functions are restored.
Important Post-Installation Information
After installing your new 2008-2012 Express 1500 BCM, some vehicles may require additional electronic ‘relearn’ or synchronization procedures. These are often simple but may require a bi-directional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the airbag system. This is a safety-critical step that requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to satisfy the traction control system.
- No Core Charge: You can keep your old part; there is no core charge or need to return the original module.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and climate controls. It’s the ‘brain’ for your vehicle’s body and cabin electronics.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and settings for your specific vehicle’s options and features. This ensures it communicates properly with the other modules and functions correctly upon installation.
Is this a plug-and-play part?
Because we program it to your VIN before shipping, it is as close to plug-and-play as possible. However, as noted, some vehicles may require an additional ‘relearn’ procedure for the airbag or brake systems, which may need a professional scan tool.
What if my original part number is not on your list?
The part numbers listed are the most common ones this module replaces. If your number is different, please contact us with your VIN. We can verify compatibility to ensure you receive the correct part for your vehicle.
Can I install this myself?
If you are comfortable with basic hand tools and removing interior dash panels, you can likely perform the installation. The key is to be careful with the plastic trim and electrical connectors. Following our guide and consulting a repair manual is recommended.
