From the Technician’s Bench: I’ve seen countless GM trucks and SUVs from this era come into the shop with bizarre electrical issues. The owner has often spent hundreds trying to chase down a wiring problem when the BCM was the root cause all along. The biggest hurdle used to be programming. A new, blank module from the dealer meant the vehicle had to be towed in for programming. A pre-programmed unit like this one is a game-changer for both DIYers and professional shops. It turns a multi-step, expensive repair into a simple, 15-minute component swap. It’s the smartest way to fix these common BCM failures.
This 2003-2006 Avalanche 1500 Body Control Module is the perfect solution for restoring your vehicle’s electrical system. It is also a direct replacement for a wide range of other GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, and Escalade. Please verify fitment using the compatibility list and your part number to ensure a perfect match. Get your vehicle back to 100% with this reliable, pre-programmed BCM.
Frequently Asked Questions
Is this module difficult to install?
No, installation is straightforward for most people with basic tools. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, unplug the electrical connectors from your old module, remove it, and install the new one. The entire process often takes less than 15 minutes.
Do I really not need to go to the dealer for programming?
That’s correct. We handle the programming for you. By providing us with your vehicle’s VIN when you order, we flash the module with the correct software and vehicle-specific information. This makes it a true plug-and-play part, saving you the significant cost and hassle of a dealership visit.
My airbag light is on. Will this fix it?
This module often resolves the underlying communication issues that can trigger an airbag light (like DTC B1001). However, after installation, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool to sync the new BCM with the airbag system and turn off the light. This is a simple procedure for any qualified mechanic.
What does ‘No Core Charge’ mean?
A core charge is a deposit that other companies charge you until you send back your old, broken part. We do not have a core charge. You can keep your old part, dispose of it, or sell it without any need to return it to us, simplifying the process for you.
Will this BCM fit other GM vehicles besides the Avalanche?
Yes, this specific 2003-2006 Avalanche 1500 Body Control Module is interchangeable with many other part numbers and fits a wide range of GM trucks and SUVs from that era, including the Silverado, Sierra, Tahoe, Yukon, Escalade, and Hummer H2. Always check the fitment list on the product page to confirm compatibility with your specific year and model.
