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? A failing Body Control Module (BCM) is often the culprit behind a host of baffling issues, from flickering lights and malfunctioning power windows to a dead instrument cluster or even a no-start condition. This OEM-quality replacement BCM, part number 15198116, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation.
Diagnosing a Faulty Body Control Module
The BCM is the central command center for your vehicle’s body electronics. When it begins to fail, it can create a chain reaction of problems that may seem unrelated. If you’re experiencing any of the following symptoms, a failing BCM is the likely cause.
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC system failures, including a blower motor that won’t turn on or works intermittently.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, leading to the vehicle not starting or the alarm sounding randomly.
- ✔ Inaccurate or non-functional gauges on the instrument panel.
- ✔ Communication errors with other vehicle modules, causing a variety of DTCs.
Why Choose Our Pre-Programmed 2003-2007 Silverado BCM?
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program each module to your vehicle’s specific VIN before shipping. This critical step ensures 100% compatibility and communication with your truck’s existing systems, eliminating the need for expensive and time-consuming programming at a dealership. Simply plug it in, and you’re ready to go. Built to strict OEM standards, this module provides a reliable, long-lasting repair for your vehicle’s electrical system.
Installation and Post-Install Considerations
Installation is a straightforward process for any DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before you begin is recommended. While the module is plug-and-play, some vehicles may require a simple post-installation procedure. If your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. In some cases, a Brake Pedal Position sensor relearn may also be necessary. Best of all, there is no core charge, so you don’t have to worry about the hassle and expense of returning your old part.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
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, the security system, and HVAC controls.
Is this module ready to install right out of the box?
Yes. We program the module to your vehicle’s VIN before it ships. This makes it a true plug-and-play solution, saving you a trip to the dealership for programming.
What if my airbag light stays on after I install the new BCM?
If the airbag light is on, the vehicle requires an ‘SDM Primary Key Setup’ procedure. This syncs the new BCM with the airbag system and must be done with a professional-grade diagnostic scan tool.
Do I need to send my old part back?
No. We do not require a core return for this part. You can keep or dispose of your old module without any additional charges.
Will this fit my 2007 Silverado or Sierra ‘Classic’ model?
Yes, this BCM is compatible with the ‘Classic’ body style for 2007 models, which have the creased door skin. It is a direct-fit replacement for those specific trucks.
