Are You Tired of Chasing Electrical Gremlins?
Is your 2002-2006 Avalanche 2500 or other GM truck suffering from bizarre electrical issues? One moment the power windows work, the next they don’t. The HVAC blower motor has a mind of its own, and mysterious warning lights appear on your dash. These frustrating problems often point to one central culprit: a failing Body Control Module (BCM). Instead of paying for expensive diagnostic time and dealership programming fees, take control with this VIN-programmed BCM, designed to restore your vehicle’s full functionality right out of the box.

From the Mechanic’s Bay: A customer brought in a 2005 Silverado 2500 with a frustrating list of complaints: the radio would cut out, the dome light wouldn’t work, and the driver’s power window was dead. They had already replaced the window switch and checked fuses with no luck. The issue was a failing BCM creating communication errors across the vehicle’s network. Installing a programmed 15136225 BCM didn’t just fix the window—it solved all three problems at once. This single component restored the vehicle’s entire electrical harmony, saving the owner from further diagnostic costs and parts swapping.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and climate control systems.
Is this module difficult to install?
Installation is typically straightforward for those with basic mechanical skills. The BCM is usually located under the steering column or behind the center dash. The process involves disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. Most installations take less than 15 minutes.
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and its specific equipment configuration onto the module before we ship it. This ensures it communicates perfectly with your vehicle’s other computers, just like the original part, for a true plug-and-play experience.
Will I need to go to the dealership after installing this?
In most cases, no dealership visit is required. Our VIN programming handles the primary setup. In some vehicles, if the airbag light appears after installation, a simple ‘Setup SDM Primary Key’ procedure may be needed with a professional scan tool to sync the airbag system.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, the best way to be 100% certain is a professional diagnosis with a high-level scan tool that can read BCM-specific trouble codes (DTCs). Common signs include multiple, unrelated electrical failures occurring at the same time.
Does this part fit vehicles other than the Avalanche 2500?
Yes. This programmed 15136225 BCM is compatible with a wide range of 2002-2007 GM trucks, vans, and SUVs, including the Chevrolet Silverado, Suburban, Tahoe, Express; GMC Sierra, Yukon, Savana; Cadillac Escalade; and Hummer H2. Please verify the part number or use our fitment tool to confirm compatibility.
