Is your GMC Savana 3500 plagued by bizarre electrical issues? Flickering lights, malfunctioning power windows, a dead radio, or warning lights that come and go without reason are all classic signs of a failing Body Control Module (BCM).

Don’t let electrical gremlins keep your work van off the road. This direct-fit replacement Body Control Module is the reliable solution you need to restore full functionality to your vehicle.

Simply provide us with your vehicle’s VIN (Vehicle Identification Number) after your purchase, and our technicians will flash the module with the latest GM software updates and your vehicle’s exact configuration. This means no expensive trips to the dealer for programming, no special tools required—just a straightforward installation process to get you back in business.

From the Diagnostic Bay
We had a 2011 Savana 3500 work van come into the shop that was driving the owner crazy. The dome lights would stay on intermittently, the power locks would work one minute and not the next, and the battery would drain overnight. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a costly and time-consuming dealer visit, we installed one of our pre-programmed modules. The installation took less than an hour, and instantly, all the strange electrical issues were gone. The van was back on the job the same day, saving the owner significant downtime and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning radio or instrument cluster gauges.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ False warning lights appearing on the dashboard (e.g., ABS, Airbag, Check Engine).
- ✔ Wipers or climate control operating incorrectly.
Your Plug-and-Play Solution for the 2008-2012 Savana 3500 BCM
This module is a direct replacement for a wide range of original GM part numbers, ensuring broad compatibility. By programming the unit to your VIN, we ensure that all the specific options and features your vehicle came with from the factory will work correctly right out of the box. There is no core charge, so you can keep your old part. After installation, some vehicles may require simple relearn procedures, which are detailed below.
Post-Installation Procedures
While this module is designed for a simple installation, some vehicle systems may need to be re-synchronized after the BCM is replaced. These are standard procedures that can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on certain models to ensure proper brake light operation and to prevent issues with the traction control system.
Please note: Specific relearn procedures can vary by exact year and model. Always consult a factory service manual or a qualified technician for detailed guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, wipers, the security system, and the instrument panel, among other things.
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready for installation, loaded with the latest GM software for your specific vehicle.
Where is the BCM located on a GMC Savana?
On most 2008-2012 GMC Savana and Chevrolet Express vans, the Body Control Module is located in the center of the dashboard, often accessible by removing lower dash panels. Always consult a repair manual for the exact location and removal procedure for your specific vehicle.
What happens if the airbag light comes on after I install the new BCM?
This is a normal security feature. The new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with a professional-grade diagnostic tool.
Is this a new or used part?
This is a high-quality, tested component guaranteed to restore your vehicle’s function. We ensure each module meets strict performance standards and is programmed with the most current software available from the manufacturer for your VIN.
