Is Your GM Truck or Van Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or a battery that mysteriously drains overnight, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and seemingly unrelated issues. This replacement BCM, part number 15194169, is the definitive solution to restore full functionality and reliability to your vehicle.
The Plug-and-Play Advantage: Programmed to Your VIN
Forget expensive trips to the dealership for programming. The biggest hurdle in replacing a BCM is ensuring it’s correctly configured for your vehicle’s specific options. We eliminate that problem entirely. Simply provide us with your vehicle’s VIN during checkout, and our experts will flash this module with the latest GM software updates specific to your truck or van. It arrives at your door ready for installation, saving you time, money, and hassle. This is the most straightforward way to replace your faulty 2003-2007 Express 2500 BCM or related GM vehicle module.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, mirrors, or door locks working intermittently or not at all
- ✔ Horn sounding unexpectedly or not working
- ✔ Vehicle security system faults or false alarms
- ✔ Inaccurate gauge readings on the instrument cluster
- ✔ Parasitic battery drain leading to a dead battery
- ✔ Wipers behaving erratically
Installation and Post-Install Procedures
Replacing the BCM is typically a straightforward process. On most trucks like the Silverado and Sierra, it’s located under the steering column. On vans like the Express and Savana, it’s found in the center dash area. Once the new module is installed, your vehicle should start and run. However, depending on your specific model and options, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to have this BCM programmed?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN when you place your order, and the module will arrive ready to install.
What information do you need from me?
All we need is your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the BCM with the correct software and settings for your specific vehicle configuration.
Is it difficult to find and replace the BCM?
On most compatible trucks (Silverado/Sierra), the BCM is located under the driver’s side dashboard, near the steering column. On vans (Express/Savana), it’s typically in the center dash. It’s generally accessible for someone with basic auto repair skills.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
