Are you experiencing frustrating electrical problems in your GM truck or van? Issues like flickering dash lights, malfunctioning power windows and locks, or a security system that acts up on its own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent symptoms. This replacement BCM is the reliable, straightforward solution to restore your vehicle’s full functionality.
This module is a direct replacement for a wide range of GM vehicles, including the Silverado, Sierra, Express, and Savana models from 2003-2007. To make your repair as simple as possible, we program the module to your vehicle’s specific VIN before it ships. This means it arrives ready for installation, loaded with the latest software from GM, saving you a costly and time-consuming trip to the dealership for programming.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or alarm randomly activating.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ “Service Electrical System” or other warning messages on the dash.
- ✔ Intermittent starting problems or no-crank situations.
- ✔ Communication issues with diagnostic scan tools.

Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require additional steps after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated 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 system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control function.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
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 functions. This includes power windows, locks, interior and exterior lighting, security system, wipers, and various other comfort and convenience features.
Is this part difficult to install?
The physical installation is typically straightforward, involving the removal of a few trim panels and unplugging the old module to plug in the new one. Because we pre-program it to your VIN, you avoid the complex software setup, making the process much easier for a DIY mechanic or local shop.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will then program the module specifically for your vehicle before we ship it out.
What happens if the airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
