Restore Full Electronic Function to Your GM Truck or Van
Are you battling strange and frustrating electrical problems in your 2003-2007 GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a no-start condition can often be traced back to a single component: 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 wide range of confusing symptoms. This replacement BCM, part number 15194169, is the reliable solution to get your vehicle back to 100% functionality.
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and the power door locks had a mind of their own. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. We installed a VIN-programmed module just like this one, and instantly, all the electrical gremlins vanished. It’s a common failure, but seeing the relief on the owner’s face when everything just *works* again is why we do this.
Why Choose Our Pre-Programmed 2003-2007 GM BCM?
Replacing a BCM isn’t just about swapping parts. A new module must be programmed specifically to your vehicle’s Vehicle Identification Number (VIN) and its unique options. Our service eliminates the need for an expensive trip to the dealership. We handle the programming for you before we ship. Simply provide us with your VIN during checkout, and you’ll receive a module that is ready for installation, loaded with the latest software updates from GM. This ensures optimal performance and compatibility right out of the box.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ The instrument cluster displaying incorrect information or warning lights.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ The engine won’t crank or start due to security system communication failure.
- ✔ Horn honking unexpectedly or not working at all.
Installation and Post-Install Steps
This BCM is typically located under the steering column on pickup models (Silverado, Sierra) or in the center of the dash on van models (Express, Savana). While the physical installation is straightforward for a skilled DIYer or technician, please be aware of potential post-installation procedures. Depending on your specific vehicle, you may need a professional scan tool to perform an ‘Airbag System Sync’ if the airbag light appears, or a ‘Brake Pedal Position Relearn’ to ensure proper brake light and traction control operation. Always consult a factory service manual for detailed instructions.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for the part to function.
Is this a plug-and-play part?
For most functions, yes. Because we program it to your VIN, it eliminates the need for dealership programming. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake position sensor, which requires a compatible scan tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if the airbag light comes on after installation?
This can happen. It means the new BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Will this fix my specific electrical problem?
This BCM will fix problems directly caused by a faulty module. While the symptoms listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
