If you’re dealing with bizarre electrical problems in your 2013-2014 Savana 1500 Van, you know how frustrating it can be. One minute the power locks work, the next they don’t. The security light is flashing for no reason, or worse, the van won’t start at all. As a technician with over two decades of experience, I’ve seen these exact issues hundreds of times, and they almost always point to a failing Body Control Module (BCM).
The BCM is the central command center for your van’s body electronics. When it fails, it creates a cascade of confusing and intermittent problems that can be a nightmare to diagnose. This isn’t just an inconvenience; for a work van, it means downtime and lost income. That’s why we offer this direct-replacement BCM, fully programmed to your vehicle’s specific VIN with the latest GM software updates. This eliminates the need for an expensive trip to the dealership for programming, getting you back on the road and back to work faster.
A Technician’s Notebook: The Phantom No-Start
I had a fleet customer bring in a 2013 Express Van—nearly identical to the Savana—with an intermittent no-start. The battery was good, the starter was fine, but sometimes it just wouldn’t crank. He’d already replaced parts chasing the problem. After hooking up my pro-level scan tool, I noticed a slew of communication error codes (U-codes) pointing to the BCM. The module was intermittently failing to recognize the key’s security chip. We replaced it with one of our pre-programmed BCMs, and the van started reliably every time. It’s a classic failure mode, and having a ready-to-install solution saved my customer a full day of vehicle downtime.
Is Your Van Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Intermittent no-start or security system light flashing
- ✔ Power windows, door locks, or mirrors working erratically or not at all
- ✔ Interior or exterior lights flickering, staying on, or not turning on
- ✔ Horn honking randomly or not working when pressed
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (e.g., U0140, U0155) or specific body functions
- ✔ Inaccurate gauge readings on the instrument cluster
Your Straightforward BCM Installation Guide
Installing your new 2013-2014 Savana 1500 BCM is a manageable job for a confident DIYer or any professional mechanic. On these 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: Carefully remove the necessary dash trim panels to gain access to the BCM. It’s often mounted to a bracket behind the radio or climate controls.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the exact same position as the old one. Securely reconnect all electrical connectors, making sure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, etc.—to confirm the repair.
Important Post-Installation Steps
Because this BCM is pre-programmed, most functions will work immediately. However, depending on your vehicle’s specific configuration, a couple of quick sync procedures may be needed. Please note:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is required 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 correct brake light and traction control operation. This also requires a capable diagnostic tool.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the exact software and settings for your Savana’s specific options. This ensures it works correctly right out of the box, saving you a trip to the dealer.
Is this a plug-and-play part?
Yes, for the most part. Because it comes pre-programmed to your VIN, it is designed to be a direct installation. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor, which needs a professional scan tool.
What tools are needed for installation?
Basic hand tools are all that’s required for the physical replacement: a socket set and some panel removal tools are usually sufficient. A professional-grade scan tool is only needed if a post-install relearn procedure is necessary.
Will this fix my van’s no-start problem?
If the no-start is caused by the BCM failing to recognize the key or communicate with other modules (a very common issue), then yes, this part is the correct fix. It directly addresses security system and communication failures originating from the BCM.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
