Is your GMC Savana or Express van experiencing bizarre electrical issues? The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a wide range of frustrating problems that can be difficult to diagnose. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle. It arrives pre-programmed with the latest GM software, specifically flashed to your vehicle’s VIN, making installation straightforward and eliminating the need for an expensive trip to the dealership.
From the Diagnostic Bay
We had a 2011 Savana 3500 work van come into the shop with a complaint of a dead battery every morning. The owner had already replaced the battery twice and the alternator once, with no luck. A parasitic draw test showed a significant power drain even with the key off. After isolating circuits, we traced the draw back to the BCM. It was keeping several circuits awake internally, long after the van was shut down. Replacing the faulty BCM with a VIN-programmed unit like this one solved the problem instantly. It’s a classic example of how a failing BCM can mimic other, more common component failures.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following symptoms, your BCM is the likely culprit:
- ✔ Power windows or door locks operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ The radio or instrument cluster gauges behaving strangely.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Inconsistent A/C and heater blower fan operation.

Post-Installation Information:
While this BCM is programmed for a straightforward installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed by a professional with a capable scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
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, security system, wipers, and instrument panel displays.
Do I need to program this module?
No. We handle the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready to install.
Where is the BCM located on my Savana or Express van?
On most 2008-2012 Savana and Express vans, the BCM is located in the center dash area. However, location can vary by model, so it’s always best to confirm with a service manual for your specific vehicle.
What happens if I don’t provide my VIN?
We cannot ship your order without the VIN. The programming is essential for the module to communicate correctly with your vehicle’s other systems. We will contact you to obtain the VIN if it is not provided.
Is this a simple DIY installation?
For someone with moderate mechanical skill, replacing the BCM is generally straightforward. However, due to the potential need for post-installation relearn procedures (like for the airbag system), we recommend installation by a qualified technician with the proper diagnostic tools.
My original part number isn’t 10382479, but it’s in the list. Will this work?
Yes. All the part numbers listed are interchangeable. This module serves as a direct replacement for any of the part numbers shown in the description.
