Is Your Avalanche 2500 Plagued by Electrical Gremlins?
When your dependable Chevy Avalanche starts acting up with strange electrical issuesโthe A/C quits, the power locks have a mind of their own, or warning lights appear for no reasonโitโs more than just an annoyance. It undermines the reliability you count on. These frustrating, intermittent problems often point to a single culprit: a failing Body Control Module (BCM). This VIN-programmed BCM is the definitive, hassle-free solution to restore complete and reliable control over your truck’s essential electronic functions.
Common Symptoms & Your Solution
A failing BCM can cause a cascade of confusing issues. If you’re experiencing any of the following, this module is the targeted repair you need:
- Intermittent or non-functional 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 Diagnostic Trouble Codes (DTCs) like B1001.
- Security system malfunctions that can lead to a no-start condition.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer in your vehicle that manages and controls a wide range of electronic accessories not related to the engine. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and the HVAC system.
Why is VIN programming so important?
VIN programming loads your truck’s specific software and security information onto the BCM. Without it, the module won’t be able to communicate correctly with other computers in your vehicle, like the Engine Control Module (ECM) or the airbag system. Our pre-programming makes the installation plug-and-play.
Is this a difficult part to install?
For most DIYers with basic tools, this is a very manageable job. The BCM is typically located under the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. It often takes less than 30 minutes.
What if my airbag light is on after installation?
In some cases, the new BCM needs to be electronically introduced to the airbag system (SDM). If the airbag light stays on, a professional scan tool is required to perform a ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any well-equipped repair shop.
Do I need to return my old BCM?
No. There is no core charge for this 2002-2006 Avalanche 2500 body control module 15136877. You can keep or dispose of your old part at your convenience.
