Restore Control and Reliability to Your GM Vehicle
If you’re dealing with baffling electrical issues in your 2008-2012 GMC Savana 3500 Van—like power windows with a mind of their own, flickering interior lights, or a security system that randomly acts up—you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can impact the daily operation and safety of your work van or personal vehicle.
This replacement Body Control Module is your direct, hassle-free solution. We take the guesswork and expensive dealership trips out of the equation. Simply provide your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your vehicle’s configuration. It arrives at your door ready to install, saving you hundreds in programming fees and valuable time.
Case Study: A Tricky Diagnosis
A local contractor brought in his 2011 Savana 3500 work van with a list of bizarre symptoms. The radio would turn on and off, the dome lights would stay on, and occasionally the power locks wouldn’t respond. He’d already replaced the battery and checked fuses, but the problems persisted. In my shop, we see this often. Intermittent electrical faults that don’t follow a pattern are a classic sign of BCM failure. After confirming stable power and ground to the module, we scanned for codes and found a U0140 – Lost Communication With Body Control Module. Instead of sending him to a dealer for a costly replacement and programming session, we provided a VIN-programmed Savana 3500 Body Control Module. He installed it himself in under an hour, and his van was back to being a reliable workhorse the same day.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Erratic power windows, door locks, or security system alerts.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ Instrument cluster gauges behaving abnormally or warning lights (like the airbag light) illuminating without cause.
- ✔ The radio or infotainment system malfunctioning.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Your vehicle’s horn sounding unexpectedly.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
A Straightforward Guide to BCM Installation
Installing your new Savana 3500 Body Control Module is a manageable job for a confident DIYer or any professional mechanic. For the Savana and Express vans, the BCM is typically located in the center dash area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Access the Module: You will likely need to remove a few dash panels to gain access to the BCM. On Savana/Express vans, it’s often behind the lower center dash trim or glove box area.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, radio, etc.—to confirm proper operation.
- Perform Relearns (If Needed): As noted below, some vehicles may require a post-installation procedure for the airbag system or brake pedal position sensor if related warning lights appear.
Important Post-Installation Information
While this module is programmed for a plug-and-play experience, some vehicle systems may require recalibration after the BCM is replaced. This is a normal part of the process.
- Airbag System Sync: If the airbag (SRS) warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the systems and is not an indication of a faulty part.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
- No Core Charge: You are not required to return your old module. There is no core charge or fee associated with this purchase.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for your specific model for detailed instructions and torque specs.

Frequently Asked Questions
Why do you need my VIN to program the Body Control Module?
Your Vehicle Identification Number (VIN) allows us to load the exact software and vehicle-specific options (like power seats, sunroof, security system, etc.) into the BCM. This ensures it communicates correctly with all other modules in your vehicle for a seamless, plug-and-play installation.
Is this part truly plug-and-play?
Yes, for the vast majority of installations. Because we program it to your VIN, you avoid the need for expensive dealer tools for initial setup. In some cases, as noted in the description, a secondary relearn procedure (like for the airbag or brake sensor) may be needed if a warning light appears, which can be done with most professional scan tools.
Where is the BCM located on a 2010 Savana 3500 Van?
On the 2008-2012 GMC Savana and Chevrolet Express vans, the Body Control Module is typically located in the center of the dashboard, often behind the lower trim panel or integrated into the fuse block assembly. You will need to remove some dash components for access.
What happens if I don’t perform the ‘Airbag System Sync’?
If the airbag warning light comes on after installation and you do not perform the sync procedure, the light will remain on, and more importantly, the airbag system (SRS) may not function correctly in the event of a collision. We strongly recommend having this done by a qualified technician if the light appears.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, saving you the hassle and cost of return shipping.
