Is Your GM Vehicle Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, unresponsive power windows or locks, or strange warning messages on your dash, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable problems. This is especially true for hardworking vehicles like the 2008-2012 GMC Savana 1500 Van.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ False warnings appearing on the instrument cluster (e.g., “Service Theft System”).
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Radio or climate control systems behaving unpredictably.

Don’t let a faulty BCM keep your vehicle off the road. This is a direct-fit replacement Body Control Module for a wide range of GM vehicles, including the Savana, Express, Tahoe, Impala, and more. The most critical feature is our complimentary programming service. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software specific to your vehicle’s options. This ensures that when the part arrives, it’s ready for installation without requiring an expensive trip to the dealership for programming.
Post-Installation Requirements
While our goal is to make this repair as simple as possible, some vehicle systems may require a recalibration or ‘relearn’ procedure after the new BCM is installed. This is a normal part of the repair process.
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
This versatile Body Control Module is a direct replacement for a wide array of GM cars, trucks, and SUVs. Please verify your original part number against our extensive cross-reference list or use the fitment chart to confirm compatibility with your specific model.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions like power windows, locks, interior and exterior lighting, the security system, and wipers, among other things.
Why do you need my VIN?
Your vehicle’s VIN allows us to program the BCM with the exact software and settings for the specific options your vehicle was built with. This makes the installation process much smoother and avoids a mandatory trip to the dealer.
Is this part difficult to install?
The BCM is typically located under the dashboard and is accessible with basic hand tools. The physical replacement is straightforward for a DIYer with moderate experience. Our pre-programming service eliminates the most difficult step, which is the software setup.
Will this fix my “Service Airbag” light?
If the light is caused by a faulty BCM, this part will resolve the issue. However, after installation, you will likely need to have the “Setup SDM Primary Key in BCM” procedure performed with a compatible scan tool to sync the modules and turn off the light.
What if I install it and some things still don’t work?
First, check if any post-install procedures, like the brake pedal position relearn, are needed for your model. If issues persist, it’s possible there is another fault in the system, such as a bad switch or wiring, that the BCM was being incorrectly blamed for.
Do I have to send my old part back?
No. This part is sold without a core charge, so you can keep your original module. There is no need to return anything to us.
