Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2003-2007 Chevrolet Silverado, GMC Sierra, or other compatible GM vehicle? Flickering lights, a dead instrument cluster, unresponsive power windows, or a security system that prevents your truck from starting are all classic signs of a failing Body Control Module (BCM). This vital component is the central hub for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and seemingly unrelated problems. This VIN-programmed BCM, part number 15137393, is the direct-fit, reliable solution to get your truck’s systems working in harmony again.
Is Your Vehicle Showing Signs of BCM Failure?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, a faulty module is the likely cause:
- ✔ Unresponsive or intermittent power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or behave erratically.
- ✔ HVAC and climate control problems, such as a blower motor that won’t work or switches modes on its own.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, including false alarms or a no-start condition where the engine cranks but won’t fire.
- ✔ Inaccurate or non-functional gauges on your instrument panel.

Installation and Post-Install Notes
Physical installation is simple for most DIY mechanics. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnect the battery, unplug the connectors from the old module, remove it, and install the new one. However, due to the complexity of modern vehicle systems, some post-installation procedures may be necessary:
- Airbag System Sync: If the airbag light is on after installation, 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 relearn may be required to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a Body Control Module do on a Silverado?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and HVAC controls.
Is this part difficult to install?
The physical replacement is very easy, typically taking less than 15 minutes with basic tools. It’s usually located under the steering column and involves unplugging a few electrical connectors.
Do I need to go to the dealer after installing this?
No. We pre-program the module to your vehicle’s VIN, so it’s ready for installation right out of the box. This saves you the time and expense of dealership programming.
What if my airbag light is on after I install the new BCM?
This can happen. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fit other GM trucks besides the Silverado 2500?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Sierra, Tahoe, Suburban, Yukon, Escalade, and Hummer H2. Please check the fitment list to confirm for your specific vehicle.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without any hassle or need to return it.
