End the Electrical Headaches in Your GM Truck or SUV
Are strange and unpredictable electrical problems making your truck feel unreliable? Flickering lights, unresponsive power windows, or a climate control system with a mind of its own are classic signs of a failing Body Control Module (BCM). This central command unit is the brain behind your vehicle’s essential creature comforts and security features. When it fails, it can cause a cascade of frustrating issues. Restore full functionality and confidence in your vehicle with our expertly programmed GM Body Control Module, a direct-fit solution for your 2007-2011 Chevrolet Avalanche 1500 and many other GM models.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, often leading to confusing diagnostics. If you’re experiencing any of the following, this module is the definitive solution:
- Intermittent or total loss of HVAC and blower motor controls.
- Power windows, door locks, or interior/exterior lights that work sporadically or not at all.
- An active airbag warning light, often accompanied by DTC B1001.
- Security system malfunctions, causing no-start conditions or stalling.
- A variety of seemingly unrelated diagnostic trouble codes (DTCs) pointing to body system failures.
Instead of chasing individual component failures, address the root cause with a reliable, new BCM. This is the correct 2007-2011 Avalanche 1500 Body Control Module to get your truck’s electronics communicating properly again.

Expert Insight: The Groundwork for a Lasting Repair
From over 20 years of hands-on diagnostics, I’ve seen countless technicians and DIYers replace a BCM only to have similar problems return. Why? Often, the original failure was caused or worsened by a poor ground connection. The GMT900 platform (your Avalanche, Silverado, Tahoe, etc.) is known for having ground points that can corrode or loosen over time, especially the main one under the driver’s door on the frame rail. Before installing your new 2007-2011 Avalanche 1500 Body Control Module, take 10 extra minutes to locate, clean, and tighten the main body and chassis grounds. This simple step ensures the new module has a stable connection, preventing voltage spikes and ensuring a permanent, reliable fix.
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. This means it is ready for a plug-and-play installation right out of the box, with no additional programming required.
Where is the Body Control Module located?
On most compatible models, including the Avalanche, the BCM is located under the driver’s side dashboard, near the steering column. Installation typically takes less than 15 minutes with basic tools.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag code like B1001, the new BCM needs to be synced with the airbag system’s SDM (Sensing and Diagnostic Module). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync, not a full programming session.
Is this the correct part for my vehicle?
This module is a direct replacement for a wide range of 2007-2013 GM trucks and SUVs and is interchangeable with numerous part numbers, including 25844480, 25835966, and 15901388. Please verify the fitment list on this page or contact us with your VIN to confirm compatibility.
Will this 2007-2011 Avalanche 1500 Body Control Module fix my specific electrical problem?
The BCM controls a vast array of body functions. If you are experiencing multiple issues listed in the symptoms section (e.g., HVAC, windows, and locks are all acting up), it is highly likely that the BCM is the culprit. This module is designed to be the comprehensive solution for those failures.
