Is Your Envoy XUV Plagued by Bizarre Electrical Problems?
If you’re dealing with flickering lights, power windows with a mind of their own, or dashboard warnings that come and go, you’re likely facing a failing Body Control Module (BCM). In your GMC Envoy, Chevy Trailblazer, or other GM SUV from this era, the BCM is the central command for dozens of electronic functions. When it fails, it can make your reliable vehicle feel unpredictable and unsafe. This isn’t just an inconvenience; it’s a critical failure that needs a reliable solution.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways. You might be experiencing:
- Power windows or door locks not working correctly or at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- Erratic windshield wiper behavior.
- Instrument cluster warning lights illuminating randomly.
- Communication issues leading to Diagnostic Trouble Codes (DTCs) like U-series codes.
The solution is a dependable, correctly configured BCM. This unit is a direct-fit replacement, but with one crucial advantage: we program it to your vehicle’s specific VIN before it ships.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I’ve seen countless people try to save a few dollars by installing a used BCM from a junkyard. It almost never ends well. These modules are not interchangeable. They are coded with the specific options and security information of the vehicle they came from. Installing a mismatched BCM can cause even more problems, from non-starting issues to disabling critical safety systems. Our VIN-programming service isn’t just a convenience; it’s the only way to ensure the replacement part communicates correctly with all other modules in your vehicle, providing a lasting and reliable repair. This is the correct way to fix your vehicle with a programmed 2004-2005 Envoy XUV BCM 15114669.
Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicles may require additional steps to sync all systems perfectly. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag module.
- Brake Pedal Position Relearn: In some cases, a recalibration of the brake pedal position sensor may be required to ensure proper brake light and traction control operation.
We provide this programmed 2004-2005 Envoy XUV BCM 15114669 as the core component of your repair, but always recommend consulting a factory service manual or a qualified technician if you are unsure about these final steps.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function.
Is this BCM difficult to install myself?
For someone with moderate mechanical experience, the physical replacement is straightforward. The BCM is typically located on or near the fuse box. The most critical part, the programming, is already done for you. However, be aware of the potential post-installation procedures that may require a professional scan tool.
Will this definitely fix my car’s electrical problems?
This BCM is the solution for failures within the module itself, which cause the symptoms listed above. While it is the most common point of failure for these issues, you should always ensure your vehicle has been properly diagnosed. Check for wiring issues or faulty grounds as part of a complete diagnosis.
What happens if the airbag light comes on after I install it?
This is a known possibility and is related to the vehicle’s security system. The BCM and the airbag module (SDM) need to be electronically re-introduced. A repair shop with a high-end diagnostic tool (like a GM Tech 2 or equivalent) can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do all the part numbers listed on the sticker need to match mine?
No. As long as your original part number is included in our compatible list (15122670, 15065293, 15114669, 15191621, 9352135), this module will serve as a correct replacement once it is programmed to your VIN.
