Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your GMC Sierra, Chevy Silverado, or other GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind a host of problems, from malfunctioning lights and power windows to a no-start condition. This OEM-quality BCM, interchangeable with part numbers 15198116 and 15116066, is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership programming and ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop with a classic case of ‘gremlins.’ The radio would cut out, the driver’s side window worked intermittently, and the security light was on. The owner had already replaced the battery and checked all the fuses. The initial scan pointed towards the BCM, but a quick check of the main BCM ground point under the driver’s side kick panel revealed significant corrosion. After cleaning the ground, some issues were resolved, but the security light remained. This confirmed the BCM itself had an internal failure, likely stressed by the poor ground over time. Replacing the BCM with a VIN-programmed unit like this one finally cleared all the codes and restored 100% functionality. Always check your grounds first, but don’t be surprised if the BCM is the final piece of the puzzle.
Common Symptoms of a Failing GM BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ HVAC system failures, including an inoperative blower motor or incorrect temperature control.
- ✔ An active security light on the dash, potentially causing a no-start or crank-no-start condition.
- ✔ The airbag warning light is illuminated, often with diagnostic trouble codes like B1001.
- ✔ Intermittent loss of communication between various vehicle modules.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, door locks, interior/exterior lighting, wipers, and the security system. It acts as a central command for these functions.
Is this part difficult to install?
No, installation is typically very simple. The BCM is usually located under the driver’s side dashboard near the steering column. It involves disconnecting the battery, unplugging the electrical connectors from the old module, removing it, and installing the new one. The entire process often takes less than 10 minutes.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific configuration and software into the BCM. This ensures all features work correctly and that the BCM can communicate properly with other modules like the ECU and airbag system. Without it, you would have to take the vehicle to a dealer for expensive programming.
Will this fix my airbag light?
A faulty BCM can cause the airbag light to come on. Replacing it with this programmed module often resolves the issue. However, if the light remains on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed with a professional scan tool to sync the systems.
Is there a core charge for my old part?
No, there is no core charge for this part. You can keep your old module without any need to return it, saving you time and hassle.
