Are you experiencing frustrating electrical issues with your Chevrolet Express or GMC Savana van? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often traced back to a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement Body Control Module, part number 95151084, is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process simple. Unlike a trip to the dealership, which involves towing, high labor costs, and programming fees, our BCM arrives at your door pre-programmed to your van’s specific VIN. We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This means no additional programming is required for most vehicles, allowing for a straightforward installation.
From the Diagnostic Bay
We had a customer with a 2011 Express 2500 work van that was draining its battery every two days. He had already replaced the battery twice and the alternator once, with no luck. The parasitic draw was intermittent and impossible to track with a standard multimeter. After connecting a professional scan tool, we monitored the BCM data and noticed it was failing to put various subsystems to ‘sleep’ after the key was off. It was randomly waking up the interior lights and radio modules. A new, properly programmed BCM solved the phantom drain, saving the owner from further costly and incorrect repairs.
Diagnosing Your 2008-2012 Express BCM
A faulty BCM can manifest in numerous ways. If you’re noticing several of the following issues, your Body Control Module is the likely culprit. This module is the direct solution for these common failures.
Common Failure Symptoms
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, etc.).
- ✔ Power windows or door locks operating intermittently or not at all.
- ✔ Vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ The radio or climate control system turning on or off by itself.
- ✔ A persistent battery drain that kills the battery overnight (parasitic draw).
- ✔ Communication errors with other vehicle modules (DTC U-codes).
Simple Installation & Post-Install Notes
Installation is typically plug-and-play. Simply locate your old BCM (often in the center dash area on Express/Savana vans), disconnect the battery, swap the modules, and reconnect the battery. However, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional scan tool to sync the modules and is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure correct brake light and traction control operation.
This BCM is a direct replacement for a wide range of part numbers, including: 10382479, 15093910, 15276271, 15299986, 15819552, 20815898, 22860591, 25892622, and many more. Please verify your part number or consult the extensive fitment list to confirm compatibility.
Frequently Asked Questions
What does the BCM do on my 2009 Express Van?
The Body Control Module (BCM) acts as the brain for your van’s electronic accessories. It controls functions like power windows, door locks, interior/exterior lighting, the security system, and the instrument cluster.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. The BCM is typically located in the center dash area. Since we pre-program the module to your VIN, it’s a plug-and-play process that doesn’t require a trip to the dealer for programming.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. We cannot ship the module until we have this information to program it correctly for your specific vehicle.
What if my airbag light comes on after I install the new BCM?
This is uncommon, but if it happens, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix a battery drain problem?
Yes, a failing BCM is a very common cause of parasitic battery drain. If your BCM is not allowing the vehicle’s electronic systems to go into ‘sleep’ mode, it will slowly drain the battery. Replacing it with this programmed unit is a frequent fix for that issue.
