Restore Your SUV’s Electrical System with a Plug-and-Play Solution
Are you dealing with frustrating electrical issues in your Trailblazer, Envoy, or Saab 9-7X? Flickering lights, unresponsive power windows, or a vehicle that refuses to start can often be traced back to a failing Body Control Module (BCM). This vital component acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. We offer a straightforward, reliable solution: a replacement BCM, part number 15122670, that arrives at your door fully programmed to your vehicle’s specific VIN.
Common Symptoms & Your Solution
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, this module is the definitive fix you need:
- Power windows, door locks, or interior lights operating erratically or not at all.
- Warning lights on the dashboard that have no clear cause.
- Problems with the radio or climate control systems.
- Intermittent no-start conditions where the engine cranks but won’t fire up.

Expert Insight: The GMT360 Platform BCM
As a technician who has worked on countless GM trucks from this era, I can tell you that BCM failure on the GMT360 platform (Trailblazer, Envoy, etc.) is a very common issue. These modules control dozens of functions, and over time, internal components can degrade. The biggest hurdle for most DIY mechanics or even independent shops has always been the required programming. A new BCM from the dealer is just a blank box; it requires a special scan tool and a subscription to GM’s service to make it work. Our pre-programming service completely removes that barrier, turning a complicated electronic repair into a manageable component swap. This is the exact service I would recommend to a friend to save them time, money, and a trip to the dealer.
Installation Note
After installing this Programmed 15122670 BCM, a couple of simple relearn procedures may be necessary depending on your vehicle. If the airbag light is on, a “Setup SDM Primary Key in BCM” procedure is needed to sync the systems. Additionally, a “Brake Pedal Position Relearn” might be required for proper brake light and traction control function. These procedures can be performed by most professional scan tools.
Frequently Asked Questions
Is this BCM truly plug-and-play?
For most functions, yes. Because we program it to your VIN, it will operate the main systems immediately. However, as noted, you may need a professional scan tool to perform a quick relearn procedure for the airbag (SDM) system and the brake pedal position sensor to ensure all systems are 100% synchronized.
