Is Your Savana 2500 Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a haywire security system, or other strange electrical behavior in your 2013-2019 GMC Savana 2500, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your van’s body electronics, coordinating everything from your interior lights and door locks to your instrument cluster and security system. When it starts to fail, it can cause a cascade of frustrating and unpredictable problems.
Don’t let a faulty BCM keep your work van off the road. This is a direct-fit replacement Body Control Module, part number 22820314 (also compatible with 22915542), that arrives at your door fully programmed to your vehicle’s specific VIN. This means no expensive trips to the dealership for programming—it’s a true plug-and-play solution designed to get you back in business quickly and affordably.
Common Symptoms of a Failing Savana 2500 Body Control Module
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on at all).
- ✔ The security system or keyless entry system works sporadically or not at all.
- ✔ False warnings or error messages appearing on the instrument cluster.
- ✔ The horn honking unexpectedly or not working when pressed.
- ✔ Issues with the heating and A/C blower motor controls.
- ✔ Battery drain issues caused by the BCM not allowing other modules to go to sleep.

Installation and Post-Install Procedures
For the Savana and Express vans, the BCM is typically located in the center dash area. Installation is a matter of disconnecting the battery, accessing the module, swapping the electrical connectors, and securing the new unit. While the module is plug-and-play, some vehicles may require a couple of simple relearn procedures after installation:
- Airbag System Sync: In some cases, the new BCM may cause the airbag warning light to illuminate. This is because it needs to be synced with the airbag’s SDM (Sensing and Diagnostic Module). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration might be necessary. This can also be performed with a compatible diagnostic tool.
There is no core charge for this part. You can keep your original module.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It’s the brain for your vehicle’s body electronics.
Do I need to take my van to the dealer for programming?
No. The main benefit of this part is that we program it for you before shipping. Simply provide your VIN during checkout, and the module will arrive ready to install, saving you time and money.
Where is the BCM located on my Savana 2500?
On most 2013-2019 GMC Savana and Chevrolet Express vans, the BCM is located behind the dashboard, typically in the center console area. Always consult a service manual for the exact location on your specific vehicle.
What is a VIN and why do you need it?
VIN stands for Vehicle Identification Number. It’s a unique 17-digit code for your specific vehicle. We use it to load the correct software and settings for your van’s options, ensuring the new BCM works perfectly.
What if my airbag light is on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Is this part compatible with other vehicles?
Yes, this BCM fits a wide range of GM vehicles including the Chevrolet Express, Impala, Traverse, and Cadillac CTS, among others. Please verify that your original part number is 22820314 or 22915542 to ensure proper fitment.
