Is Your GM Truck or SUV Plagued by Baffling Electrical Problems?
If you’re dealing with flickering lights, a malfunctioning security system, or power accessories that have a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This OEM-quality BCM, part number 15136877, is the definitive solution for restoring order to your 2003-2007 Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, or other compatible GM vehicles.
Symptoms of a Failing Body Control Module

- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ HVAC and climate control systems that won’t function correctly.
- ✔ An active airbag warning light, often accompanied by diagnostic trouble code B1001.
- ✔ Security system malfunctions, leading to no-start conditions or false alarms.
- ✔ Intermittent operation of windshield wipers.

Frequently Asked Questions
What does a BCM do on a 2003-2007 GM truck?
The Body Control Module acts as the central computer for your truck’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and HVAC blower motor operation.
Is this BCM ready to install out of the box?
Yes! This BCM is pre-programmed to your vehicle’s VIN before shipping. This ensures it works correctly with your specific options and security system, making it a true plug-and-play installation with no dealership visit required.
Where is the BCM located on my Silverado or Sierra?
On most 2003-2007 GM trucks and SUVs like the Silverado, Sierra, Tahoe, and Yukon, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
What if my airbag light is on after installing the new BCM?
If the airbag light is illuminated after installation, it means the new BCM needs to be synchronized with the airbag system’s SDM. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to return my old BCM?
