2004 – 2007 GMC SAVANA 1500 Body Control Module (BCM) 15137395 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with frustrating electrical glitches in your 2004-2007 GMC Savana 1500, like doors that won’t lock or headlights flickering unexpectedly during a long delivery run? As a seasoned mechanic who’s seen countless vans sidelined by faulty body control modules, I know how these issues can disrupt your workday. Questions like “Why is my Savana 1500 BCM causing power window failures?” or “How to fix intermittent dash lights in a 2004 GMC van?” often lead owners here. This pre-programmed BCM, part number 15137395, is your direct solution—flashed with the latest GM updates using your VIN for seamless integration. It replaces compatible numbers like 10383536, 15116066, and others, ensuring no guesswork. Beyond basic repair, it restores reliable operation, clears persistent DTC codes related to body functions, and enhances overall vehicle stability, especially for tradesmen relying on the commercial package (opt PRP). My analysis from years in the shop shows that ignoring BCM faults can lead to cascading problems, like failed theft deterrent systems, but this unit prevents that with precise programming.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, BCM failures in the 2004-2007 GMC Savana 1500 often stem from water intrusion or electrical shorts, especially in vans used for commercial work. One frequent problem is erratic door locks and power accessories—caused by degraded internal circuits—that leave you vulnerable on job sites. This pre-programmed BCM resolves it by recalibrating signals, ensuring locks engage reliably and preventing theft risks. Another issue: flickering interior lights or non-responsive gauges, often triggering DTC codes like U0140, which can distract during night drives. Replacing with this unit clears those codes and stabilizes voltage, as I’ve seen in diagnostics where old modules failed under load. For tradesman packages, intermittent alarm malfunctions disrupt security; this BCM’s updated firmware fixes that, improving towing reliability by maintaining stable power to trailer connections. Don’t overlook battery drain from faulty relay controls— a common culprit in these years—that drains power overnight. Our analysis shows this replacement cuts diagnostic time, with expert tips like checking harness connections first to avoid repeats. Real scenario: A client with a Savana 1500 hauling tools faced constant no-start due to BCM glitches; post-replacement, it ran flawlessly, saving downtime.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your Savana 1500.
- Disconnect the battery to ensure safety, then locate the BCM in the center dash (for models with opt PRP).
- Remove the old module by unplugging connectors and unbolting it carefully—inspect for corrosion as a pro tip.
- Install the new BCM, reconnecting all harnesses securely to avoid loose connections that could cause DTCs.
- Reconnect the battery and perform any necessary relearns: If no-start occurs, cycle the key (on for 10 minutes, off for 30 seconds, repeat 3 times) for theft system reset.
- Test all body functions like lights and locks; consult a tech for advanced steps if needed.
