Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet Express, Silverado, or GMC Sierra plagued by mysterious electrical problems? A faulty Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, unresponsive power locks, erratic HVAC behavior, or even a no-start condition. This OEM-quality BCM, interchangeable with part number 15116066 and others, is the definitive solution for a wide range of 2002-2007 GM trucks and vans. As the central command center for your vehicle’s body electronics, replacing a failing BCM is critical to restoring dependability and safety.
Common Symptoms of a Failing GM BCM
- ✔ Unresponsive or intermittent power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ HVAC system failures, such as a blower motor that won’t work or climate controls that are inoperative.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, leading to the engine not starting or the alarm sounding unexpectedly.
- ✔ Communication errors between various electronic modules on the vehicle’s data network.
Solving Electrical Problems with a 2004-2007 Express 2500 BCM
This module is the correct component for your workhorse van. When the 2004-2007 Express 2500 BCM begins to fail, it can disrupt daily operations. Our VIN-programmed module ensures that once installed, your van’s specific options and features work exactly as they did from the factory. There is no need for an expensive trip to the dealership for programming—we handle it for you before it ships. This makes the repair process faster and more affordable, getting your van back on the road and back to work.
Plug-and-Play Installation
Our most significant benefit is the pre-shipment VIN programming. When you place your order, provide your vehicle’s 17-digit VIN. We will flash the module with the latest software from General Motors, ensuring it is perfectly matched to your vehicle’s configuration. This eliminates the need for expensive scan tools or dealership intervention, making the installation a true plug-and-play process. While installation is straightforward, please note that in some cases, a ‘Setup SDM Primary Key in BCM’ procedure may be needed if the airbag light appears, which requires a professional scan tool.
Frequently Asked Questions
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
Is this part difficult to install?
Installation is typically simple and can be done in minutes. The BCM is usually located under the steering column or in the center dash area. Disconnecting the battery before you begin is recommended.
What does ‘VIN Programmed’ mean?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and factory options into the module before we ship it. This makes it ready for installation without any additional programming required by a dealer.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A qualified technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Which part numbers does this BCM replace?
This module is a direct replacement and is interchangeable with a wide range of part numbers, including 15116066, 10367690, 15136225, 15198116, 15257043, and many more.
