If your GMC Savana work van is off the road due to bizarre electrical issues, you’re not just inconvenienced—you’re losing money. As a technician with over 20 years of experience, I’ve seen firsthand how a failing Body Control Module (BCM) can sideline a perfectly good vehicle with a cascade of frustrating problems. This isn’t just a part; it’s the central command for your van’s body electronics. This replacement BCM, a direct fit for part number 15194170, is your simple, reliable solution to get back to work.
We take the guesswork and dealer hassle out of the equation. Before this module ships, we program it to your van’s specific Vehicle Identification Number (VIN). This ensures it communicates flawlessly with your existing systems right out of the box. No expensive trips to the dealership for programming are needed. You can restore critical functions like power locks, windows, interior lighting, and HVAC controls, eliminating the gremlins that have been plaguing your workday.
From the Diagnostic Bay: The Contractor’s Van
A local electrician brought in his ’06 Savana 1500, completely stumped. The dome lights wouldn’t turn off, the power locks worked only when they felt like it, and his A/C blower was dead—a nightmare on a hot day. He’d already replaced the battery and checked fuses, wasting valuable time. On my scan tool, I saw a handful of communication codes pointing to the BCM. These modules, especially in hard-working vans, often fail from heat cycles and vibration. We installed a VIN-programmed BCM, and in less than 10 minutes, every single issue was resolved. He was back on the road to his next job site that same afternoon, avoiding a multi-day wait at the dealer.
Is Your Work Van Showing These Electrical Faults?
A faulty BCM is the root cause of many seemingly unrelated electrical problems. If you’re experiencing any of the following, this module is the likely solution for your 2004-2007 Savana 1500 BCM issues:
- ✔ The security light stays on, or the van won’t start (Passlock issues).
- ✔ Power windows, door locks, or mirrors are inoperative or work intermittently.
- ✔ HVAC controls are unresponsive, or the blower motor won’t turn on.
- ✔ The airbag warning light is illuminated, often with a DTC like B1001.
- ✔ Interior or exterior lights behave erratically, staying on or not working at all.
- ✔ Your scan tool shows communication loss or other body-related diagnostic trouble codes.
Get Your Van Back on the Job: Quick Installation Guide
This is a repair you can confidently do yourself, typically in under 10 minutes. For the Savana and Express vans, the BCM is located in the center of the dash.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the BCM: On your Savana van, you’ll find the module behind an access panel in the center dash area. It’s a black box with several multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Remove any mounting screws or clips holding the old module and set it aside.
- Install the New BCM: Mount your new, pre-programmed BCM in place and securely reconnect all the electrical connectors. You’ll hear a click as they lock in.
- Power Up: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all functions—lights, locks, windows, and HVAC—to confirm the repair is complete.

Frequently Asked Questions
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s specific software and options package onto the module before we ship it. This makes the installation plug-and-play, as the BCM will correctly recognize features like your specific lighting, security system, and power accessories without needing a dealer’s computer.
My airbag light is on. Will this fix it?
Yes, a faulty BCM is a common cause of an airbag light with DTC B1001. After installing this module, the light should go off. If it remains on, a simple ‘Setup SDM Primary Key’ procedure may be needed with a bi-directional scan tool to re-sync the systems.
What tools do I need for the installation?
For most installations, you’ll only need basic hand tools to access the module, like a socket wrench to disconnect the battery and possibly a screwdriver or trim removal tool for the dash panel. No special programming tools are required.
Is this part compatible with other GM part numbers?
Yes, this BCM is a direct replacement and interchangeable with numerous part numbers, including 15116066, 15136225, 10383536, and 15194170. It consolidates multiple older parts into one reliable solution.
