Is your GMC Savana 3500 plagued by bizarre electrical issues? Flickering lights, malfunctioning power windows, a security system with a mind of its own, or a dead battery for no reason are classic signs of a failing Body Control Module (BCM). Don’t let these electrical gremlins disrupt your workday and cost you money. This pre-programmed BCM is the definitive, reliable solution to restore your van’s critical functions and get you back to business without a costly trip to the dealership.
Common Symptoms & Your Solution
A faulty BCM acts like a problematic nerve center for your vehicle, leading to a host of frustrating and intermittent issues. If you’re experiencing any of the following, this module is the solution you need:
- Power System Malfunctions: Windows, door locks, or interior lights that work sporadically or not at all.
- Security & Anti-Theft Problems: A security light that stays on, or a vehicle that refuses to start due to a false anti-theft trigger.
- Instrument Cluster Errors: Gauges behaving erratically, warning lights illuminating incorrectly, or a complete loss of the cluster display.
- HVAC Control Issues: Inconsistent or non-functional heating and air conditioning controls.
- Communication Faults: Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001 indicating a loss of communication with the BCM.
Replacing your old unit with our Programmed Savana 3500 Body Control Module directly addresses these problems at their source, restoring the stable, predictable performance your work depends on.

From the Technician’s Bench: We had a contractor with a 2011 Savana 3500 who was about to lose a big job. His van’s security system would randomly engage, preventing it from starting. He’d already replaced the battery and checked the ignition switch. The dealership quoted him over a thousand dollars for a new BCM and programming. He was losing time and money every day. We sent him this pre-programmed module. He installed it in his workshop in under an hour, and the van fired right up. No more security light, no more starting issues. He was back on the job site the next morning. That’s the difference a reliable, ready-to-install part makes.
Frequently Asked Questions
Why is providing my VIN so important?
Your Vehicle Identification Number (VIN) allows us to program the Body Control Module with the exact software and vehicle-specific options (like power windows, keyless entry, etc.) that your Savana 3500 came with from the factory. This step is critical for a true plug-and-play installation and avoids compatibility issues.
Is this part difficult to install?
For someone with moderate mechanical experience, the physical installation is straightforward. The BCM is typically located under the dashboard. The most important part is disconnecting the battery before you begin. While our programming handles the software side, some vehicles may require a simple relearn procedure for certain systems (like the brake pedal position sensor) after installation, which can be done with a capable scan tool.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep, discard, or recycle your original module at your convenience.
What happens if the airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the vehicle’s airbag system (SDM). If the airbag light is on after install, a ‘Setup SDM Primary Key in BCM’ procedure will need to be performed by a qualified technician with a professional-grade diagnostic tool. This is a standard procedure and is not indicative of a faulty part.
How can I be sure the BCM is my problem?
The best way is a professional diagnosis. However, if you are experiencing multiple, unrelated electrical issues across different systems (e.g., power locks, interior lights, and instrument cluster all acting up), the BCM is a very likely culprit as it controls all of these functions.
