Is your GMC Savana van experiencing bizarre electrical problems? You’re in the right place.
The Body Control Module, or BCM, is the central command center for your van’s body electronics. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster. When the BCM starts to fail, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose. Instead of paying for expensive diagnostic time and dealership pricing, get a reliable, pre-programmed solution.
This is a direct-fit replacement Body Control Module for your 2008-2012 GMC Savana 3500 and many other GM vehicles. We take the guesswork out of the repair by programming the module to your vehicle’s specific VIN before we ship it. This ensures a smoother installation process, getting your work van or passenger van back on the road with minimal downtime.
From the Diagnostic Bay
We had a 2011 Express van come in that was driving the owner crazy. The dome lights would randomly turn on while driving, the radio would shut off, and sometimes the power locks wouldn’t respond. The battery was also draining overnight. After checking the battery and alternator, we suspected a parasitic draw. Tracing it led us straight to a faulty BCM that wasn’t letting the vehicle’s systems go to ‘sleep’. Swapping in a VIN-programmed BCM like this one solved all the issues in one go. It’s often the simple fix for a very complex-seeming problem.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, or door locks.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Instrument panel gauges behaving erratically or warning lights appearing for no reason.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Unexplained battery drain that leaves you with a dead battery.
Your Plug-and-Play Savana 3500 Body Control Module Solution
Don’t settle for a used module that might have the same issues or a blank one that requires expensive dealer programming. Our service provides a fully functional BCM that is flashed with the latest GM software updates and configured specifically for your van’s options using the VIN you provide. This makes the installation process as straightforward as possible. After installation, some vehicles may require a simple relearn procedure for the brake pedal position sensor or airbag system, which can often be done with a high-end scan tool. Please refer to the post-installation procedure notes for details.
Post-Installation Procedures
While this module is programmed for your vehicle, certain security and safety systems may require recalibration after installation.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration may be needed.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module do on my Savana Van?
The BCM is a computer that manages most of the non-engine related electronic systems in your van. This includes power locks, windows, lights, wipers, the security system, and communication between other modules.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module before shipping it to you.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. On Savana and Express vans, it’s usually located in the center dash area. The most critical part is ensuring any required post-install relearn procedures are performed.
What happens if the airbag or brake relearn procedures are not done?
If the airbag light is on and the sync is not performed, the airbag system may not function correctly in an accident. If the brake pedal relearn is needed and not done, your brake lights or traction control system may not operate as intended.
Is there a core charge for my old BCM?
No, there is no core charge. You can keep your original module.
