Are you battling frustrating electrical gremlins in your GM truck, van, or SUV? Flickering lights, unresponsive power windows, a dead HVAC system, or a security light that prevents your vehicle from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated issues. Restore full functionality and peace of mind with our OEM-quality GM 15116066 Body Control Module, pre-programmed specifically for your vehicle’s VIN.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn on by itself, the driver’s side power window worked intermittently, and the AC blower would quit on hot days. The owner had already replaced the window switch and the blower motor resistor with no luck. After hooking up our scanner, we saw a handful of communication codes pointing to the BCM. A new, VIN-programmed module fixed every single issue in under 10 minutes. It’s often the central component that owners overlook, leading to wasted time and money on other parts.
Common Symptoms of BCM Failure
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC system malfunctions, such as a blower motor that won’t turn on or stays on.
- ✔ Illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Security system errors, including a no-start condition where the engine cranks but won’t fire.
- ✔ Intermittent electrical functions that seem to have no logical cause.
- ✔ Diagnostic Trouble Codes (DTCs) related to body systems and communication networks.

Forget expensive dealership visits and the hassle of programming. We handle the complex part for you. Simply provide your vehicle’s VIN during checkout, and we will program this module with the latest GM software specific to your vehicle’s configuration. This ensures that all onboard systems communicate correctly right out of the box. This module is a direct replacement for a wide range of GM vehicles, including the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, Yukon, and Cadillac Escalade from 2002-2007.
Installation and Post-Install Notes
Installation is straightforward for DIYers and professionals alike. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before swapping the module is recommended. While our programming resolves most issues, some vehicles may require a simple relearn procedure.
- 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 to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
- No Core Charge: You are not required to return your old module, saving you time and shipping costs.

Is this BCM ready to install right out of the box?
Yes! As long as you provide your vehicle’s VIN at checkout, we will program the module so it’s fully compatible with your vehicle’s options. It’s a true plug-and-play solution.
Where is the BCM located on my 2005 GMC Sierra?
On most GM trucks and SUVs from this era, including the Sierra, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
What happens if I don’t provide my VIN?
We cannot ship the module without a VIN. The programming is essential for the module to function correctly with your vehicle’s specific systems, such as power windows, security, and HVAC controls.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (like DTC B1001), this part will resolve the root cause. However, after installation, the system may require an ‘SDM Primary Key Setup’ with a professional scan tool to clear the light.
Do I have to return my old BCM?
No. This product comes with no core charge, so you can keep your old part without any additional fees or hassle.
