Is your GMC Savana 3500 suffering from frustrating and unpredictable electrical problems? When your work van is down, your business is down. Strange issues like flickering lights, non-responsive door locks, or a climate control system with a mind of its own aren’t just an annoyance—they’re a sign of a failing Body Control Module (BCM). Get your essential vehicle back in service quickly with this expertly VIN-programmed BCM, engineered to restore full functionality and dependability to your van’s electronic systems.

- An illuminated airbag warning light, often with Diagnostic Trouble Codes (DTCs) like B1001.
- Security system malfunctions that can lead to a no-start condition.
- A variety of other body-related DTCs that point to a communication breakdown.

Expert Insight: Why VIN Programming is Non-Negotiable
In GM vehicles of this era, the BCM is the ‘traffic cop’ for dozens of electronic functions. It constantly communicates with the Engine Control Module (ECM), Airbag Module (SDM), and others. When you install a generic, non-programmed BCM, these modules can’t recognize each other, leading to persistent error codes, non-functional features, or even a vehicle that won’t start. Our VIN programming service flashes the module with your van’s exact factory configuration, making the new BCM a perfect digital match. This is the secret to a successful, hassle-free repair that lasts.
Don’t let a faulty BCM keep your business parked. This Programmed 2004-2007 Savana 3500 BCM is the most efficient and reliable way to solve your van’s electrical issues and get back to work with confidence. It is a direct replacement for part numbers 15136225, 15116066, 15198116, and more.
Frequently Asked Questions
What exactly does the Body Control Module do on my Savana?
The BCM is a computer that supervises and controls many of your van’s non-engine related functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC (heating and air conditioning) system. When it fails, you see a wide range of seemingly unrelated electrical issues.
Is this BCM truly ‘plug-and-play’?
Yes. Because we program the module to your vehicle’s VIN before shipping, it is ready for installation right out of the box. In most cases, you simply disconnect the battery, swap the modules, reconnect the battery, and you’re done. No dealership visit is required for programming.
What if my airbag light is on after installation?
In some cases, the new BCM may need to be synchronized with the vehicle’s airbag system (SDM). This is a simple procedure called ‘Setup SDM Primary Key in BCM’ that can be performed with a professional-grade scan tool. This is only necessary if the airbag warning light appears after the BCM is installed.
Do I need to return my old BCM?
No. We do not have a core charge for this part. You can keep, discard, or recycle your old module at your convenience, which simplifies the process for you.
How can I be sure the BCM is the problem?
While a professional diagnosis is always best, a failing BCM is the most common cause for having multiple, unrelated electrical issues at once (e.g., the power locks, radio, and dome light all acting up). If you are experiencing several of the symptoms listed above, the BCM is the most likely culprit.
