Restore Your Van’s Electrical System with a VIN-Programmed BCM
If you’re dealing with bizarre and frustrating electrical problems in your 2013-2021 Express 2500 Van, you’re not alone. As a technician with over two decades of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable workhorse into a source of constant headaches. From flickering lights to a van that won’t start, the BCM is the central hub for your vehicle’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it’s a hit to your productivity and peace of mind.
This is your direct, no-hassle solution. We are offering a genuine GM Body Control Module (interchangeable with part numbers 22915542 and 22820314) that comes fully programmed to your vehicle’s specific VIN. Just provide us with your VIN at checkout, and we’ll load the latest GM software onto the module before it even leaves our facility. This means no expensive trips to the dealership for programming, no special equipment needed for the initial setup. You get a part that’s ready to install right out of the box, getting you back on the road faster.
A Technician’s Notebook: The Ghost in the Work Van
I remember a 2015 Express 2500 that came into my bay with a list of symptoms that made no sense together. The driver said the radio would randomly shut off, the dome light would stay on, and occasionally, the power door locks would stop responding. He’d already replaced the battery and checked all the fuses. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing to the BCM. A failing BCM often acts like a bad network router for the vehicle, causing data corruption and these ‘ghost’ problems. We installed a VIN-programmed module just like this one, and every single issue vanished instantly. It’s a classic case where shotgunning parts costs more time and money than correctly diagnosing the central controller.
Common Signs of a Failing BCM
A faulty BCM can manifest in numerous ways. If your vehicle is showing any of these signs, this module is the likely solution, especially if you see communication codes like U0140, U0155, or U0164.
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ The security system or alarm going off for no reason, or a ‘Service Theft Deterrent System’ message.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Instrument cluster gauges behaving erratically or warning lights staying on.
- ✔ Wipers or the horn activating on their own or not working when commanded.
Your Straightforward BCM Installation Guide
Installing your new Express 2500 BCM is a manageable job for a confident DIYer or a quick task for any professional. In most Express and Savana vans, the BCM is located in the center dash area, often accessible after removing a few trim panels.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before starting any electrical work.
- Locate the BCM: On Express/Savana vans, it’s typically mounted behind the center dash console. You may need to remove the radio or climate control trim panels for access. On other models like the Impala or Acadia, it’s usually on the driver’s side, under the dash.
- Disconnect and Remove: Carefully unplug all 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 and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test the functions: windows, locks, lights, etc.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. If you encounter either of the following, a simple relearn procedure with a bi-directional scan tool will be needed:
- Airbag Light: If the airbag warning light is on after installation, a technician must perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake System: On some models, a ‘Brake Pedal Position Sensor Relearn’ may be necessary to ensure correct brake light and stability control operation.

Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and vehicle-specific options (like power windows, keyless entry, etc.) that your vehicle came with from the factory. This ensures a seamless installation and proper function.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
Is this a guaranteed fix for my vehicle’s problems?
This module will fix issues directly caused by a faulty BCM. While the symptoms listed are classic indicators of BCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes like wiring or sensor faults.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn require a professional-grade, bi-directional diagnostic scan tool. Most local repair shops have this equipment if you find these procedures are necessary for your vehicle.
Will this Express 2500 BCM work in my Savana 2500?
Yes. As you can see in our verified fitment list, this BCM is used across many GM platforms, including the Chevrolet Express and GMC Savana vans, which are mechanically identical. The VIN programming ensures it works correctly for your specific model.
