Restore Full Electronic Functionality to Your GM Vehicle
Is your 2006-2011 Buick Lucerne or other compatible GM vehicle suffering from bizarre and frustrating electrical problems? Flickering lights, malfunctioning power windows, a dead instrument cluster, or security system faults are often not isolated issues but symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of seemingly unrelated problems. This replacement Body Control Module, part number 25826125, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We once had a 2010 Chevy Impala in the shop where the owner had spent hundreds replacing the power window motor and switch, yet the window still wouldn’t work. They were convinced the wiring was bad. After a quick scan, we found communication faults pointing directly to the BCM. The BCM wasn’t sending the correct signal to the window circuit. We installed a VIN-programmed BCM, and not only did the window start working perfectly, but the intermittent dome light and radio issues the owner hadn’t even mentioned were also resolved. It’s a classic case of the BCM being the hidden root cause of multiple electrical gremlins.
Is Your 2006-2011 Lucerne Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following issues, a failing Body Control Module is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Malfunctioning instrument panel gauges or warning lights.
- ✔ Problems with the security system, keyless entry, or remote start.
- ✔ Intermittent issues with the radio or climate control systems.
- ✔ A ‘Service Theft System’ or other warning messages on the dash.
- ✔ The vehicle fails to start despite a good battery and starter.
The Plug-and-Play Solution: Programmed to Your VIN
Replacing a BCM isn’t just about swapping hardware. A new module must be programmed with your vehicle’s specific Vehicle Identification Number (VIN) and factory options to function correctly. Our service eliminates the need for an expensive trip to the dealership. Simply provide us with your VIN during checkout, and our technicians will flash this module with the latest GM software updates specific to your vehicle. This ensures a seamless, plug-and-play installation process right out of the box.
This module is a direct replacement for a wide range of part numbers, including: 10382479, 15093910, 15276271, 15819552, 20815898, 22860591, 25826125, 25892622, and many more.
Installation and Post-Install Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly after the new BCM is installed.
- Airbag System Sync: If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed by a technician with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn procedure may be necessary to ensure proper brake light operation and to keep the traction control system functioning as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific installation guidance.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors most of the non-engine-related electronic functions in your vehicle. This includes power windows, locks, lights, security systems, wipers, and the instrument cluster.
Do I need to program this module?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you order, and the module will arrive ready to install, flashed with the latest official GM software for your specific vehicle.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It is usually located under the dashboard. However, as noted, some vehicles may require a simple relearn procedure for certain systems like the airbag or brake sensor, which may require a professional scan tool.
What is the process after I place my order?
After you complete your purchase, you must provide us with your 17-digit VIN. Our technicians will use this to program the BCM specifically for your vehicle’s configuration and software requirements before we ship it to you.
What if my airbag light comes on after installation?
This is a common occurrence on some GM models. It means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fit vehicles other than the Buick Lucerne?
Yes. This BCM is compatible with a vast range of GM vehicles, including the Chevy Impala, Equinox, Tahoe, Express Van, GMC Acadia, Yukon, Savana Van, Cadillac DTS, CTS, and many others. Please check the extensive fitment list on this page to confirm compatibility.
