Restore Full Electrical Function to Your GM Van
Are you battling bizarre electrical problems in your GMC Savana or Chevrolet Express van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are classic signs of 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 create a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is the definitive solution to restore your van’s systems to perfect working order.
From the Diagnostic Bay
We had a 2011 Savana 2500 work van come into the shop with a list of complaints that seemed endless. The driver said the interior dome lights would stay on, the radio would randomly shut off, and the power door locks had a mind of their own. Initial checks on fuses and wiring showed nothing obvious. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a dozen small problems, it was one central failure. Installing a pre-programmed BCM like this one resolved every single issue in one go, saving the customer significant diagnostic time and labor costs.
Solving Issues with a 2008-2012 Savana BCM
A faulty BCM can make your reliable workhorse feel unpredictable. By replacing the failing unit with this quality part, you are directly addressing the root cause of these electrical gremlins. This isn’t just a replacement; it’s a restoration of your vehicle’s core functionality. We make the process simple by pre-programming the module to your vehicle’s specific VIN before it ships. This means it arrives ready for installation, eliminating the need for an expensive trip to the dealership for software flashing.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-working power windows, mirrors, and door locks.
- ✔ Interior or exterior lights that flicker, stay on, or don’t turn on at all.
- ✔ The security system or alarm randomly activating.
- ✔ Dashboard warning lights (like the airbag light) illuminating without cause.
- ✔ Problems with the heating and A/C controls.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Radio or infotainment system malfunctions.
Installation and Post-Install Considerations
While installation is straightforward for many, please be aware of potential post-installation steps. Depending on your vehicle’s specific configuration, some systems may need to be re-synced with the new BCM. This is a normal part of the process.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s electronic accessories. It controls functions that are not related to the engine, such as power windows, locks, lights, wipers, security system, and climate controls.
Do I need to program this BCM?
No. We handle the programming for you. Simply provide your vehicle’s VIN during or after checkout, and we will flash the module with the latest GM software specific to your van before shipping.
What is a core charge?
There is no core charge for this part. You are not required to send your old, faulty BCM back to us.
My airbag light is on after installation. What do I do?
This can happen. The new BCM needs to be synchronized with the airbag’s Supplemental Deployment Module (SDM). A qualified technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a plug-and-play part?
Because we pre-program it to your VIN, it is as close to plug-and-play as possible. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake pedal position sensor after installation.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your BCM without it.
