Tired of Electrical Gremlins in Your GM Truck?
Is your 2003-2007 Sierra, Silverado, or Tahoe acting possessed? One day the A/C works, the next it doesn’t. Power windows have a mind of their own, and mysterious warning lights keep appearing on your dash.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we flash the module with your truck’s unique 17-digit Vehicle Identification Number (VIN) before we ship it. This loads all the correct software and vehicle-specific options, so it communicates perfectly with your truck’s other computers without needing any additional setup from a dealer.
Is this a difficult part to install myself?
For most of the compatible vehicles, the BCM is located under the steering column and is accessible with basic hand tools. The physical swap typically takes less than 10 minutes. The most important step is disconnecting the battery beforehand.
My airbag light is on. Will this fix it?
This module will resolve airbag lights caused by an internal BCM failure (like DTC B1001). However, after installation, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Do I need to send my old BCM back?
No. We do not require you to return your original part. There is no core charge associated with this purchase, which simplifies the process for you.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, the best way to be certain is with a proper diagnosis using a high-end scan tool. A failing BCM will often show a lack of communication with the scanner or have specific internal fault codes. Multiple, unrelated electrical failures happening at once are also a classic sign.
