Restore Full Functionality to Your GMC Savana 3500 Work Van
Is your 2004-2007 GMC Savana 3500 Van plagued by frustrating electrical problems? Flickering lights, a dead HVAC system, or power windows that have a mind of their own can bring your workday to a grinding halt. The Body Control Module (BCM) is the central command for these systems, and when it fails, it can cause a cascade of baffling issues. This replacement BCM, part number 15137394, is the definitive solution to restore your van’s reliability. We offer an expert Cloning Service, transferring all the essential data from your original module to this replacement. The result is a true plug-and-play component that requires no expensive trip to the dealership for programming, getting you back on the road and back to business faster.
Case Study: The Ghost in the Work Van
A contractor brought in his ’06 Savana 3500, a van that was his mobile office. The complaint was bizarre: the dome lights would stay on, draining the battery overnight, and the power door locks worked only when they wanted to. He’d already replaced the battery twice. A scan showed a handful of communication codes, but nothing pointed to a single component. From my 20+ years of experience with these GM platforms, I recognized the pattern immediately. These intermittent, multi-system electrical faults almost always trace back to a failing BCM. The internal logic board develops micro-fractures, causing unpredictable behavior. We performed our cloning service on a replacement 2004-2007 Savana 3500 BCM, he installed it in under 10 minutes, and every single electrical gremlin vanished. He saved hundreds by avoiding a dealership’s diagnostic guesswork and programming fees.
Is Your Savana Van Showing These Symptoms?
- ✔ The A/C or heater blower motor works intermittently or not at all.
- ✔ Power windows, door locks, or interior lights are behaving erratically.
- ✔ The security system is malfunctioning, causing a no-start condition or false alarms.
- ✔ An airbag warning light is illuminated on the dash, often with a DTC like B1001 (Option Configuration Error).
- ✔ Your scanner is pulling multiple communication or body-related fault codes.
- ✔ You’re experiencing strange grounding issues or battery drain that you can’t trace.
A Straightforward Guide to Installation
Our cloning service makes this repair incredibly simple for any DIYer or professional mechanic. Since we’ve already handled the programming, you just need to swap the modules.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: In the Savana and Express vans, the BCM is typically found in the center of the dash area, often accessible by removing a lower dash panel.
- Swap the Module: Carefully unplug the electrical connectors from your old BCM. The connectors are color-coded and keyed, so they only fit in their correct slots. Remove the old module and install the newly programmed one in its place.
- Reconnect and Test: Reconnect the battery terminal. Start the van and test all body functions—lights, locks, windows, wipers, and HVAC—to confirm the repair was successful.
- Post-Installation Checks: In some cases, a ‘Setup SDM Primary Key in BCM’ procedure may be needed if the airbag light remains on. This requires a professional scan tool. See our FAQ for more details.
