Is Your Tahoe Plagued by Bizarre Electrical Gremlins?
Are you dealing with flickering lights, a malfunctioning security system, or power windows with a mind of their own?

This pre-programmed BCM is the definitive, hassle-free solution to restore order and get your vehicle operating exactly as it should.

An Expert’s Note on VIN Programming
“Many people don’t realize that a BCM isn’t a one-size-fits-all part. Your truck has a unique combination of options—from the type of transmission to whether it has power-folding mirrors. Our VIN programming process ensures the new BCM knows exactly how your specific vehicle was configured at the factory. Installing a non-programmed module is a recipe for more problems, as it won’t know how to communicate with your other systems correctly. This pre-programming is the key to a successful, lasting repair that truly restores your vehicle’s electronic integrity.”
By installing this professionally programmed 2003-2006 Tahoe Body Control Module, you’re not just replacing a part; you’re restoring the reliability and peace of mind you expect from your vehicle. Stop chasing electrical ghosts and implement the correct, permanent fix today.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping it to you. This means it is ready for installation right out of the box, with no additional programming or dealer visits required.
What tools are needed for installation?
Installation is typically straightforward and requires basic hand tools, such as a socket set or nut driver, to access the module located under the steering column or in the center dash area. The entire process often takes less than 15 minutes.
My airbag light is on. Will this fix it?
This BCM will fix airbag light issues caused by BCM failure (like DTC B1001). However, after installation, if the light remains on, a simple ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the airbag system to the new BCM.
Is this the correct part for my Silverado or Yukon?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Suburban, Avalanche, and Express, as well as the GMC Sierra, Yukon, and Savana. Please check the detailed fitment list on this page to confirm compatibility with your exact model and year.
What does a Body Control Module actually do?
The BCM acts as a central computer for your vehicle’s non-engine related functions. It manages and controls systems like your power windows, door locks, security alarm, interior and exterior lighting, wipers, and climate control, ensuring they all work together seamlessly.
