Restore Your Van’s Electrical System with a Plug-and-Play Solution
Is your 2013-2018 Chevy Express or GMC Savana van acting possessed? Flickering interior lights, power locks with a mind of their own, a security light that won’t turn off, or even a frustrating no-start condition are all classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s body electronics, a faulty BCM can cause a cascade of confusing and disruptive problems. This isn’t just an annoyance; it can impact your work, safety, and peace of mind. Don’t let electrical gremlins sideline your workhorse van.
This is a direct-fit replacement BCM, part number 22820314 (also fits 22915542), that arrives at your door fully programmed to your vehicle’s specific VIN. We handle the complex part, loading the latest GM software before we ship. This means you can bypass the expensive dealership visit, avoid towing fees, and get your van back in service faster. For the professional mechanic, this is a huge time-saver, and for the savvy DIYer, it’s the most straightforward way to solve a complex electronic issue.
A Technician’s Notebook: The Contractor’s Van Conundrum
I remember a 2016 Express 2500 that came into my bay with a truly baffling set of symptoms. The owner, a plumber, said one day the radio wouldn’t work, the next the power locks were dead, and twice it left him stranded with a no-crank, no-start condition. His dashboard was lit up with random warnings. We checked the battery and alternatorâboth fine. A scan showed a slew of U-codes (communication errors) pointing to a network problem. After isolating circuits, we traced the communication breakdown to the BCM. It was failing intermittently, essentially scrambling the messages between modules. Installing a VIN-programmed Express 2500 Van BCM like this one solved every single issue in one go. The customer was back on the job the same day, no dealer required.
Common Signs of a Failing BCM
- â Erratic or non-functional power windows, door locks, and mirrors.
- â Interior or exterior lights flickering, staying on, or not working at all.
- â The security or anti-theft light is illuminated, often causing a no-start condition.
- â Dashboard gauges behaving incorrectly or not working.
- â Warning lights for ABS, Traction Control, or Airbags appearing without a clear cause.
- â Communication Diagnostic Trouble Codes (DTCs) such as U0100, U0140, or other U-series codes.
- â Horn sounding unexpectedly or not working.
A Straightforward Guide to Installation
- â Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- â Locate the BCM: In Express and Savana vans, the BCM is typically located in the center dash area, often behind the lower instrument panel or glove box. Consult a service manual for the exact position.
- â Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module. Keep track of all screws and clips.
- â 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 old module from its mounting bracket.
- â Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses. You should hear a click as they lock into place.
- â Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test all body functions like lights, locks, and windows.
Important Post-Installation Steps
While this Express 2500 Van BCM is pre-programmed, certain vehicle safety systems may require a ‘handshake’ with the new module. Please be aware of the following potential procedures:
- 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 module.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready for installation, saving you a trip to the dealership and their programming fees.
What is a VIN and where do I find it?
The VIN is your 17-digit Vehicle Identification Number. You can find it on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Why is my airbag light on after installing the new BCM?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key’ procedure to sync the modules and turn off the light.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Is this a difficult part to install myself?
The physical replacement is straightforward for someone with basic mechanical skills and tools. It involves removing some dash panels and swapping the module. However, be aware that post-installation procedures like an airbag or brake sensor relearn may require a professional scan tool.
