Restore Full Functionality to Your GM Workhorse
Is your 2004-2007 GMC Savana 2500 Van plagued by baffling electrical problems? One minute the air conditioning works, the next it doesn’t. The power locks have a mind of their own, and a persistent airbag light stays on your dash. These aren’t random glitches; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it fails, it can make your reliable work van feel unpredictable and unsafe. Instead of facing a costly trip to the dealership for a new module and expensive programming, we offer a simple, effective solution.
This OEM-quality module, part number 15137395, is prepared for your vehicle through our professional Cloning Service. You send us your original BCM, and we transfer its exact data—including VIN, security information, and specific options—to this replacement unit. The result is a true plug-and-play module that requires no further programming. Get your Savana, Express, or other compatible GM vehicle back in service quickly and affordably.
Case Study: The Contractor’s Van That Wouldn’t Cooperate
A local contractor brought in his ’06 Savana 2500, and he was at his wit’s end. His van was his office and his tool carrier, but it was becoming unreliable. The radio would cut out, the dome lights would flicker, and worst of all, the anti-theft system would occasionally prevent it from starting, making him late for jobs. He’d replaced the battery and checked grounds, but nothing worked. After hooking up my scanner, I saw a handful of communication loss codes (U-codes) pointing to the BCM. Instead of a new, unprogrammed module, we went with a cloned unit. The process was simple: we swapped the module in under 10 minutes, and every single issue was resolved instantly. No programming, no relearns needed. He was back on the road the same afternoon, a perfect example of how a cloned 2004-2007 Savana 2500 BCM can save a small business time and money.
Is Your GM Vehicle Showing These Electrical Gremlins?
A faulty BCM can manifest in numerous ways. Over my 20+ years in diagnostics, I’ve seen these modules cause some of the most confusing symptoms. Here’s what to look for:
- ✔ Intermittent or non-functional HVAC controls, including a blower motor that won’t turn on or stay on.
- ✔ An illuminated airbag light, often accompanied by Diagnostic Trouble Code (DTC) B1001 (Option Configuration Error).
- ✔ Erratic power accessories: windows that won’t go up or down, door locks that cycle randomly, or exterior/interior lights that don’t work correctly.
- ✔ Security system malfunctions, leading to a no-start condition where the engine cranks but won’t fire.
- ✔ Communication network problems, resulting in various U-codes being stored in other modules.
- ✔ Unexplained battery drain or strange grounding issues that are difficult to trace.
A 5-Minute Fix: Installing Your Cloned BCM
Installation is a straightforward process that most DIYers or any professional technician can complete in minutes. Our cloning service makes this a simple component swap.
- Step 1: Safety First. Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s systems.
- Step 2: Locate the BCM. In most 2004-2007 Savana and Express vans, the BCM is located in the center of the dashboard, often accessible by removing a lower dash panel. In trucks and SUVs, it’s typically found under the driver’s side dash, near the steering column.
- Step 3: Swap the Modules. Carefully disconnect the electrical connectors from your old BCM. The connectors are color-coded and have locking tabs, so they only fit one way. Remove the old module and install your new, cloned BCM in its place.
- Step 4: Reconnect and Test. Reattach the electrical connectors to the new module, ensuring they click securely into place. Reconnect the battery terminal. Start the vehicle and test all functions—lights, locks, windows, wipers, and HVAC—to confirm the repair.
Important Post-Installation Information
While our cloning service makes the 2004-2007 Savana 2500 BCM a plug-and-play part, some vehicle systems may require a final handshake. If your airbag light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a capable scan tool. In some cases, a Brake Pedal Position Relearn may also be needed. We always return your original module with the replacement, so you never have to worry about a core charge.
Verified Fitment Across the GM Lineup
This BCM is a direct replacement for part number 15137395 and is interchangeable with several other part numbers, including 15116066, 15136225, 15198116, and more. It fits a wide range of GM vehicles, including:
- Chevrolet: Avalanche 1500/2500, Silverado 1500/2500/3500 (incl. Classic), Suburban 1500/2500, Tahoe, Express 1500/2500/3500 Van
- GMC: Sierra 1500/2500/3500 (incl. Classic & Denali), Yukon & Yukon XL 1500/2500, Savana 1500/2500/3500 Van
- Cadillac: Escalade, Escalade ESV, Escalade EXT
- Hummer: H2
Note: For Savana/Express vans, this module is typically for models with the commercial tradesman package (RPO code PRP). Always verify your part number for a guaranteed match.
Why is a cloning service better than just programming a new BCM?
Cloning transfers the exact data from your original module. This preserves all vehicle-specific settings and security keys, which avoids the compatibility problems and extra programming fees that often come with a brand-new module from a dealership.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to read the data from it. We will perform the service and ship both your original module and the ready-to-install replacement back to you.
What tools are required for installation?
Typically, you only need basic hand tools like a socket set or a screwdriver to remove the lower dash panel. No special programming tools are required for the installation itself, thanks to our cloning service.
Will this fix my airbag light with code B1001?
A faulty BCM is a very common cause of a B1001 code. Replacing it with this cloned module should resolve the root cause. However, as noted in our post-installation procedures, the airbag system may need a final ‘sync’ procedure with a professional scan tool to clear the light.
Is there a core charge for this part?
No. We do not require a core deposit. Your original module is used for the data transfer and is always returned to you along with the replacement unit, so you can keep it.
