If you’re dealing with bizarre electrical issues in your 2013-2014 Chevy Express or GMC Savana van, you know how frustrating it can be. One minute the power locks work, the next they don’t. The radio acts possessed, or worse, the van won’t start reliably. As a technician with over two decades of experience, I’ve seen these exact problems hundreds of times, and the culprit is often a failing Body Control Module (BCM). This isn’t just a part; it’s the central hub for your vehicle’s body electronics, and when it goes bad, it creates chaos.
We’re offering a direct-fit, reliable solution: a replacement BCM that comes fully programmed to your van’s specific Vehicle Identification Number (VIN). This isn’t a generic, one-size-fits-all part. We load it with the latest GM software updates before it even leaves our facility. This means you can skip the expensive trip to the dealership for programming and get your workhorse back on the road faster. This is the definitive fix for the electrical gremlins plaguing your van.
A Technician’s Notebook
I remember a 2014 Express 2500 that came into the shop a few years back. The owner, a plumber, was at his wit’s end. His interior lights would stay on, draining the battery overnight, and his turn signals worked intermittently. He’d already replaced the battery and checked all the fuses. After connecting my diagnostic tool, I saw a slew of communication error codes (U-codes) all pointing back to one source. The BCM was failing to communicate properly with other modules. We installed a VIN-programmed BCM, and within an hour, every single issue was resolved. It’s a perfect example of how one component can cause a cascade of seemingly unrelated problems.
Key Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ The security system light stays illuminated, preventing the engine from starting.
- ✔ Intermittent dashboard warning lights (ABS, Airbag, Check Engine) with no other apparent cause.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140.
- ✔ Horn or radio operating unexpectedly.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: In the 2013-2014 Express and Savana vans, the BCM is located in the center of the dashboard, typically accessible after removing some dash trim panels.
- ✔ 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 and remove it from the vehicle.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Reconnect the negative battery terminal.
- ✔ Perform Final Checks: Start the vehicle and test all body functions: lights, locks, windows, radio, etc. Note the post-installation procedures below, as they may be required.
Important Post-Installation Steps
While this BCM is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new module. Please be aware of the following:
- Airbag System Sync: If your airbag warning 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: On some models, a brake pedal position sensor recalibration may be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do you need my VIN?
We require your VIN to program the BCM with the exact software and settings for your van’s specific options. This ensures everything works correctly right out of the box and prevents the need for a dealership visit.
Is this a plug-and-play part?
Yes, for the most part. The initial programming is done by us. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor, which can be done with a capable diagnostic tool.
My original part number is 22915542. Will this work?
Absolutely. This BCM, part number 22820314, is a direct replacement for part number 22915542 and several others, offering the same or improved functionality with the latest software.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens if the airbag light comes on after I install it?
This indicates the new BCM needs to be synchronized with the airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed by a mechanic with a professional-grade scan tool to resolve this.
