Are you battling frustrating electrical issues in your GM truck or van? Flickering lights, unresponsive power windows, or a security light that won’t turn off are common signs of a failing Body Control Module (BCM).

Expert Insight: Don’t Chase Electrical Gremlins
As a technician, I’ve seen countless hours and dollars wasted trying to diagnose BCM-related issues. A customer might replace a window motor, a door lock actuator, and even a radio, only to find the problem persists. That’s because the BCM is the command center. When it fails, it sends faulty signals, making good parts seem broken. Installing a properly programmed 2003-2007 Savana 3500 BCM doesn’t just replace a part; it restores order to the entire electrical system, providing a lasting fix and preventing you from throwing money at the wrong components.
This module is engineered to be a reliable, long-term solution for your vehicle. By providing us with your VIN, you ensure that the BCM you receive is a perfect electronic match, just like a part from the factory. Get your truck or van back to being the dependable tool you rely on every day.
Frequently Asked Questions
Do I need to program this BCM?
No. This Body Control Module comes pre-programmed for your specific vehicle. All you need to do is provide us with your vehicle’s 17-digit VIN when you place your order, and we handle all the programming before it ships.
Where is the BCM located on my truck or van?
On most compatible GM vans like the Savana and Express, the BCM is located in the center of the dashboard. For Silverado and Sierra pickups, it is typically found under the steering column. Always confirm the location for your specific model before beginning installation.
Will I need special tools after installation?
In some cases, yes. After installing the new BCM, certain systems may need to be re-synced using a professional-grade scan tool. This can include the ‘Setup SDM Primary Key in BCM’ procedure for the airbag system or a ‘Brake Pedal Position Relearn’. These are not always required but are a possibility.
Why do you need my VIN?
The Vehicle Identification Number (VIN) allows us to access the exact factory software and calibration files for your truck’s specific options and features. Programming the BCM with your VIN ensures it communicates perfectly with all other modules in your vehicle, just like the original part.
Is this BCM compatible with part number 15136876?
Yes. This module is a direct replacement for a wide range of original part numbers, including 15194169, 15167329, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. It is designed to fit and function perfectly in place of any of these original units.
