Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical gremlins in your 2008-2012 Chevy Express or GMC Savana van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often traced back to a single, critical component: the Body Control Module (BCM). This module acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module, part number 15948438, is the definitive solution to restore your vehicle’s factory performance and reliability.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-functional power windows, mirrors, or door locks.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The vehicle’s security system or alarm malfunctions or engages randomly.
- ✔ The horn sounds unexpectedly or doesn’t work when pressed.
- ✔ Dashboard warning lights (like the airbag light) illuminate for no reason.
- ✔ Problems with the radio, climate control, or instrument cluster functions.
Why Choose Our Programmed Express 1500 BCM?
Getting your van back on the road shouldn’t be complicated. Our service eliminates the most difficult part of the repair: the programming. A new BCM from a dealership requires expensive, specialized tools to link it to your vehicle. We handle that for you. Simply provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number) during or after checkout, and our technicians will flash the module with the latest GM software specific to your van’s configuration. This ensures a true plug-and-play installation, saving you hundreds in dealership labor and programming fees.
This module is a direct replacement for a wide range of GM part numbers, including 15948438, 25892622, 20815898, and many more, ensuring broad compatibility across various models like the Chevy Express, GMC Savana, Impala, Acadia, and Tahoe. Please verify the fitment list to confirm it matches your vehicle.
Post-Installation Notes
While this module is delivered ready for installation, some vehicles may require simple relearn procedures. For instance, if the airbag (SRS) light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. A Brake Pedal Position Relearn might also be necessary on certain models. These are standard procedures for this type of repair.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and climate controls.
Do I need to get this BCM programmed?
No. This BCM comes fully programmed to your vehicle. You must provide us with your VIN so we can load the correct software and settings before we ship it to you. This makes installation much simpler.
Where is the BCM located on my Express Van?
On the 2008-2012 Express and Savana vans, the BCM is typically located in the center dash area. Always consult a service manual for the exact location and replacement procedure for your specific vehicle.
Why do you need my VIN?
Your VIN allows us to access the specific factory software and option codes for your exact vehicle. Programming the BCM with this data ensures all features work correctly, just as they did from the factory.
Is this a difficult part to replace myself?
For someone with moderate mechanical skill, the physical replacement is straightforward. It’s typically located behind a dash panel and held in by a few bolts and electrical connectors. The main benefit of our product is that the complex programming is already done for you.
What if the airbag light comes on after I install it?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
