Tired of a Mind of Its Own? Take Back Control of Your SUV.
Is your GMC Envoy, Trailblazer, or Bravada suffering from frustrating electrical issues? Flickering interior lights, power windows that won’t cooperate, door locks acting erratically, or a security light that won’t turn off are all classic signs of a failing Body Control Module (BCM). These problems aren’t just annoying; they can compromise your vehicle’s usability and security. This isn’t just a replacement part; it’s the definitive solution to restore the reliable, predictable performance you depend on every day.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of confusing problems. You might be experiencing one or more of the following:
- Power windows, mirrors, or door locks working intermittently or not at all.
- Interior dome lights or dashboard lights staying on or not turning on correctly.
- Erratic behavior from the radio or climate control systems.
- The security system preventing the vehicle from starting.
- Communication error codes (U-codes) when scanned with a diagnostic tool.
This module is the answer. We take the guesswork and hassle out of the repair by pre-programming this Programmed GMC Envoy BCM to your vehicle’s specific Vehicle Identification Number (VIN) before it ever leaves our facility.

Expert Insight: Why Pre-Programming is a Game-Changer
As a technician with over two decades of experience, I’ve seen countless vehicle owners get stuck after installing a new module. In the past, replacing a BCM on these GM SUVs meant the vehicle was dead in the water until it was towed to a dealer for a costly programming session. Our process eliminates that entire step. By flashing the Programmed GMC Envoy BCM with your VIN data beforehand, we’re essentially performing that critical dealer-level service for you. This transforms a complex electronic repair into a manageable, plug-and-play process for a home mechanic or local garage, saving you hundreds of dollars and significant downtime.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require minor electronic relearn procedures to sync all systems perfectly. These are standard procedures that a qualified technician can perform quickly.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure proper brake light and traction control operation.
This Programmed GMC Envoy BCM is your most reliable path to resolving those persistent electrical gremlins and getting your truck back to 100%. Place your order, send us your VIN, and get ready for a smooth, predictable ride again.
Frequently Asked Questions
What exactly does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, security systems, and wipers. When it fails, these systems can behave erratically.
How do I provide my vehicle’s VIN?
After you complete your purchase, you can send us a message with your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is specific to your exact vehicle.
Is this BCM truly ‘plug and play’?
For most vehicles, yes. Because we pre-program it to your VIN, it eliminates the need for dealer-level programming. However, as noted, some models may require simple relearn procedures for systems like the airbags or brake sensor, which can be done with a capable pro-level scan tool.
My original part number isn’t 15122670, but it’s on the list. Will this work?
Yes. The part numbers listed (15065293, 15114669, 15191621, 9352135) are all interchangeable. We will be sending a compatible module that has been fully tested and programmed for your vehicle.
What tools are needed for installation?
Installation typically requires basic hand tools like a socket set and screwdrivers to access the BCM, which is usually located near the fuse box. No special programming tools are needed on your end.
What if the 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 the airbag’s computer (SDM). A repair shop with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
