Restore Full Function to Your GM SUV
Are you dealing with bizarre and frustrating electrical problems in your GMC Envoy, Chevy Trailblazer, or other GM SUV?

- Erratic or non-functional dashboard gauges.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of non-engine-related functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and dashboard gauges.
How do I know if my BCM is failing?
Common symptoms include erratic behavior of electronic components like lights, locks, and windows; dashboard warning lights coming on; or a no-start condition where the engine won’t crank. These issues often happen intermittently at first and worsen over time.
Is this module difficult to install?
The BCM is typically located in or near the front fuse box. For someone with basic mechanical skills, the physical replacement is straightforward. Since our module comes pre-programmed to your VIN, you eliminate the most difficult part of the jobโthe software configuration. However, please review the potential post-installation procedures listed.
Where do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship your BCM without it. Please double-check it for accuracy to ensure perfect compatibility.
What if my airbag light comes on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by a professional technician with a capable diagnostic tool. This is only necessary if the light appears after the swap.
Will this specific 2002-2005 Envoy XL BCM 15122670 fix my problem?
This module is the direct solution for failures of the BCM itself. While the symptoms listed are strong indicators of a bad BCM, we always recommend proper vehicle diagnostics to confirm the BCM is the root cause before ordering. This ensures you are purchasing the correct part for your repair.
