Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet Silverado, GMC Sierra, or Savana van plagued by frustrating electrical problems? A faulty Body Control Module (BCM) is often the culprit behind issues like malfunctioning lights, unresponsive power windows, erratic HVAC controls, or a persistent airbag light. This genuine OEM-quality Body Control Module, part number 15198116, is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a simple, plug-and-play installation.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving its owner crazy. The dome lights would stay on, the driver’s side power window worked only when it wanted to, and the radio would randomly shut off. After checking grounds and wiring harnesses, we connected the scanner and saw a slew of communication error codes pointing to the BCM. Instead of a costly trip to the dealer, we installed one of these VIN-programmed modules. In under 10 minutes, every single electrical gremlin was gone. The customer was thrilled to have his truck’s features working reliably again without a massive repair bill.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and interior/exterior lights.
- ✔ HVAC blower motor not working or climate controls behaving erratically.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system acting up, potentially causing a no-start condition.
- ✔ Unpredictable behavior from windshield wipers or radio.
- ✔ Communication errors between various electronic modules.

Installation and Post-Install Notes
Installation is straightforward for most DIYers. The BCM is typically located under the steering column or behind the center dash panel. Simply disconnect the vehicle’s battery, unplug the electrical connectors from the old module, remove it, and install the new one in its place. Reconnect the connectors and the battery. In some cases, additional steps may be needed:
- Airbag System Sync: If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: Certain models may require a brake pedal position sensor recalibration to ensure correct brake light operation.

Frequently Asked Questions
What is the main function of a Body Control Module?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls.
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play and saves you a trip to the dealership.
How difficult is it to replace this module?
For most individuals with basic tools, the replacement is simple and takes less than 15 minutes. It involves unplugging the old module and plugging in the new one, typically under the dashboard.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM (like with code B1001), this part will resolve the issue. However, if the light stays on after installation, a simple sync procedure with a professional scan tool is required to link the new BCM to the airbag system.
My original part number is 15116066. Will this 15198116 part work?
Yes, this module is a direct interchange for a wide range of GM part numbers, including 15116066, 15136225, and many others listed in the description, ensuring broad compatibility for your 2004-2007 Savana Body Control Module and other GM models.
