Restore Full Electrical Function to Your GM Vehicle
Are you battling persistent electrical issues in your Chevrolet Express, GMC Savana, or other GM truck/SUV? A failing Body Control Module (BCM) is often the culprit behind a frustrating array of problems, from flickering lights and malfunctioning power windows to a no-start condition. This genuine OEM-quality BCM, equivalent to part number 15194170, is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
Is Your Vehicle Showing Signs of BCM Failure?
The BCM is the central command for your vehicle’s body electronics. When it begins to fail, it can trigger a wide range of confusing symptoms. If you’re experiencing any of the following, a faulty BCM is the likely cause:
- ✔ Intermittent or non-working HVAC and blower motor controls.
- ✔ An illuminated airbag warning light, often accompanied by DTCs like B1001.
- ✔ Unresponsive power windows, door locks, or interior/exterior lighting.
- ✔ Security system malfunctions, including anti-theft system activation that prevents the engine from starting.
- ✔ A host of seemingly unrelated diagnostic trouble codes (DTCs) related to body functions.

Don’t settle for a generic, unprogrammed module that will require additional calibration. We take the guesswork out of the repair. Simply provide your vehicle’s VIN during checkout, and our technicians will program this module with the latest GM software specific to your van. This ensures all factory options and systems communicate correctly from the moment you plug it in, restoring performance and reliability. This module is a direct replacement for a wide range of part numbers, including 15116066, 15136225, 15198116, and 15194170.
Installation and Post-Install Considerations
Physical installation is straightforward. The BCM is typically located under the steering column or in the center dash area. After installation, some vehicles may require additional steps:
- Airbag System Sync: If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Frequently Asked Questions
What does a BCM do on a 2004-2007 Express 2500 Van?
The BCM acts as the central computer for your van’s body electronics. It controls functions like the power windows, door locks, interior and exterior lights, wipers, HVAC system, and the anti-theft security system.
Is this BCM ready to install out of the box?
Yes! This module is sold pre-programmed to your vehicle’s VIN. This means it’s ready for plug-and-play installation with no additional dealership programming required for most functions.
What happens if I install an unprogrammed BCM?
An unprogrammed BCM will not work correctly. It won’t have the correct software for your vehicle’s specific options, which can lead to incorrect function of various systems or even a no-start condition.
Where is the BCM located on my Express van?
On 2004-2007 Express and Savana vans, the BCM is typically found in the center dash area. On most compatible trucks and SUVs like the Silverado or Tahoe, it’s located under the steering column.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any extra fees or hassle.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (e.g., DTC B1001), this part will resolve the issue. However, after installation, the system may require an ‘SDM Primary Key’ relearn procedure with a professional scan tool to turn off the light.
