Expert Insight from Our Technicians
“On these early 2000s GM trucks and vans, the BCM is the central hub for nearly every function you interact with inside the cab. When it fails, you get chaos. The biggest mistake we see is people buying a used, unprogrammed module. It simply won’t work. The vehicle’s security system will reject it, and you’ll be left with a no-start situation. Our VIN programming service isn’t just a convenience—it’s the critical step that makes this a successful, 5-minute repair instead of a week-long headache.”- Veteran Automotive Electronics Specialist

Frequently Asked Questions
What does the BCM do on my Savana van?
The Body Control Module acts as the central computer for your vehicle’s body electronics. It manages non-engine related functions like your lights, power windows and locks, wipers, security system, and HVAC climate controls.
Is this module really plug-and-play?
Yes. Because we program it to your vehicle’s specific VIN number before shipping, it will integrate seamlessly with your truck’s existing systems. In most cases, you simply disconnect the battery, swap the module, and reconnect the battery.
What if my airbag light stays on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). This is a simple procedure called “Setup SDM Primary Key in BCM” that can be performed by a repair shop with a professional-grade 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 your old module without any extra charges or hassle.
Will this fit other GM trucks besides the Savana?
Absolutely. This BCM is compatible with a wide range of GM trucks, vans, and SUVs from 2002-2007, including the Silverado, Sierra, Tahoe, Yukon, Escalade, and more. Please check the compatibility list to confirm your specific model.
How do I know for sure my BCM is the problem?
While the symptoms listed are strong indicators, the best way to be 100% certain is a professional diagnosis. However, if you are experiencing multiple, unrelated electrical issues with things like your lights, locks, and climate control, a failing 2004-2007 GMC Savana 3500 Body Control Module is the most common cause.
