2004 – 2007 GMC SAVANA 1500 Body Control Module (BCM) 15137394 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 2004-2007 GMC Savana 1500 during a rainy delivery run, or wondered why your power locks fail unpredictably in cold weather? These frustrations often stem from a failing Body Control Module (BCM), the central hub managing everything from interior lighting to security systems in your van. As a seasoned mechanic who’s diagnosed countless GM vans, I’ve seen how moisture ingress or electrical shorts can corrupt the BCM, triggering diagnostic trouble codes (DTCs) like P1626 or U0140 that leave you stranded. Our pre-programmed BCM, part number 15137394, is your direct solution—flashed with the latest GM updates using your VIN for seamless compatibility. It replaces equivalents like 10383536, 15116066, and others, restoring smooth operation without dealership hassles. This isn’t just a swap; it’s a reliability boost that clears persistent DTC codes and enhances daily driving confidence, especially for tradesmen relying on their Savana for heavy loads. By addressing root causes like voltage spikes, you’ll notice improved electrical stability, preventing issues that could sideline your work van.

Common Issues & How This Fixes Them
Owners of 2004-2007 GMC Savana 1500 vans frequently report symptoms like non-responsive power windows, erratic wiper operation, or unexplained battery drain—often linked to a degraded BCM exposed to years of vibration and environmental stress. For instance, if you’re hauling tools and notice your headlights dimming intermittently, it could be a BCM communication failure causing voltage irregularities, potentially leading to safety risks on night jobs. Another common headache is security system glitches, where the alarm triggers randomly, tied to corrupted theft-deterrent modules within the BCM. In my shop experience, these stem from internal circuit corrosion, especially in high-humidity areas, escalating to DTCs that scanners can’t easily clear. Replacing with our VIN-programmed BCM resolves this by recalibrating the network, restoring proper signal flow and eliminating those pesky codes. Think about a real scenario: a fleet manager I advised swapped theirs after repeated no-start episodes post-rain; the new module not only fixed the issue but improved fuel pump relay consistency, boosting engine start reliability. This fix also tackles brake light malfunctions, ensuring compliance with road safety standards. By going beyond basic repairs, it prevents cascading failures, like accessory power loss during long drives, saving you from costly towing fees and downtime.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2004-2007 Savana 1500—ensuring it’s ready to ship and match your van’s configuration.
- Disconnect the battery to avoid electrical surges; locate the BCM in the center dash area, typically secured with a few bolts for easy access in models with the commercial tradesman package.
- Remove the old BCM by unplugging connectors carefully—note any corrosion on pins, as this could indicate broader wiring issues to inspect.
- Install the new BCM, reconnecting all harnesses securely; double-check for proper seating to prevent loose connections that might trigger new DTCs.
- Reconnect the battery and perform initial tests: Cycle the ignition to verify functions like lights and locks; if a no-start occurs, initiate theft relearn by turning the key to ‘on’ for 10 minutes, off for 30 seconds, repeating three times.
- Complete post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and recalibrate the brake pedal if needed for optimal safety—consult your manual or a tech for variations.
