Is your 2003-2006 Chevy Avalanche or GM truck plagued by bizarre electrical problems?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or an HVAC system with a mind of its own, the culprit is likely a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This VIN-programmed BCM, part number 15137394, is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Symptoms of a Failing GM BCM
- ✔ Unresponsive power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, such as a blower motor that won’t turn on or is stuck on one speed.
- ✔ An illuminated airbag warning light on the dashboard, often with DTC B1001.
- ✔ Vehicle security system malfunctions, leading to a frustrating no-start condition.
- ✔ Erratic behavior from windshield wipers or other electronic accessories.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs) stored in the vehicle’s memory.

Installation and Post-Install Notes
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. While our VIN programming handles the majority of the setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. This syncs the new BCM with the airbag system. In some cases, a Brake Pedal Position relearn may also be necessary. There is absolutely no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the main computer for your vehicle’s non-engine related functions. It controls the power windows, locks, lights, wipers, security system, HVAC, and other comfort and convenience features.
Will I need to take my truck to the dealership for programming?
No. This Body Control Module comes pre-programmed to your vehicle’s VIN. This allows for a simple plug-and-play installation without the need for expensive dealership programming.
Is this BCM difficult to install?
Installation is generally simple, taking under an hour for most DIYers. It involves disconnecting the battery and swapping the module, which is usually located under the driver’s side dash.
What happens if my airbag light is on after installation?
If the airbag light is on, it means the new BCM needs to be synced with the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade scan tool.
