Are you battling bizarre and frustrating electrical issues in your GM SUV? One minute the power windows work, the next they don’t.

Expert Insight: The Pre-Programming Advantage
Many owners consider buying a used BCM from a salvage yard to save money, but this is often a mistake. A used BCM is locked to the donor vehicle’s VIN and options. It will not function correctlyโor at allโin your truck without being professionally reprogrammed. This requires expensive, specialized scan tools and a trip to a dealer or high-end shop, wiping out any initial savings. Our service eliminates this entire ordeal. By programming the 2005-2006 Envoy XL BCM specifically for your vehicle before it even leaves our facility, we provide a part that works correctly the moment you install it.

Important Post-Installation Information
While this module is programmed for plug-and-play installation, some vehicles may require simple relearn procedures after the BCM is installed. These are standard procedures when modules are replaced.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the airbag module to the new BCM.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. Getting the right 2005-2006 Envoy XL BCM is the first step to a successful repair.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function.
Is this a difficult part to install myself?
For someone with moderate mechanical experience, the installation is straightforward. The BCM is typically located in or near the under-hood fuse box. The main challenge is accessing it. However, since our unit is pre-programmed, you avoid the most complex part of the jobโthe software configuration.
What if an airbag light comes on after I install it?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A repair shop with a professional-grade scan tool (like a Snap-on or Autel) can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my specific electrical problem?
This BCM corrects a wide range of common electrical issues controlled by the module, such as power accessories, lighting, and communication between other modules. While it is the solution for the vast majority of these symptoms, we always recommend proper vehicle diagnostics to confirm the BCM is the source of the fault before ordering.
Do I need to send my old BCM back?
No, there is no core charge or requirement to return your original module. You can keep it or dispose of it as you see fit.
