2004 – 2007 GM EXPRESS 3500 Body Control Module (BCM) 15137395 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2004-2007 Chevrolet Express 3500 van refusing to start due to quirky security glitches, or noticed the power windows acting up during a busy delivery run? As a seasoned mechanic who’s fixed countless vans like yours, I know how frustrating it can be when body electronics fail, especially in commercial setups with the tradesman package. Questions like “why is my Express 3500 HVAC blower intermittent?” or “how to resolve airbag DTC B1001 in a 2005 GM van?” often point straight to a faulty BCM. Enter our OEM-spec GM 15137395 Body Control Module, pre-programmed to your exact VIN for seamless plug-and-play. This unit oversees key systems like lights, locks, wipers, HVAC, and security, restoring reliability without dealership visits. It’s interchangeable with numbers like 15137395, 15116066, and others, fitting models including Express 3500 vans with opt PRP. Beyond basics, this BCM clears persistent DTC codes and boosts overall electrical stability, drawing from GM’s latest updates for long-term dependability in demanding work environments.
Common Issues & How This Fixes Them
In my two decades of diagnosing GM vans, I’ve seen failing BCMs cause havoc, especially in high-mileage Express 3500 models from 2004-2007. A common headache is loss of HVAC controls—think erratic blower speeds that leave you sweating on hot delivery days or freezing in winter hauls. This often stems from degraded internal circuits, triggering DTCs that disrupt climate functions. Replacing with our VIN-programmed 15137395 resolves this by recalibrating signals, ensuring consistent operation and clearing related codes like those for blower motors. Another frequent issue: airbag warning lights flashing with codes such as B1001, which can stem from communication breakdowns between the BCM and safety modules. Ignoring it risks safety compliance, but this module integrates flawlessly, often resetting lights post-install via a quick SDM key setup. Electrical gremlins like non-responsive power windows, door locks, or exterior lights? These arise from grounding faults or water intrusion in the center dash location—common in work vans exposed to elements. Our BCM fixes them by providing robust, updated controls that prevent intermittent failures, improving towing reliability for loaded Express models. Security malfunctions leading to no-start conditions? That’s usually a BCM glitch in the anti-theft system; the pre-programming here eliminates that, avoiding tow truck calls. Finally, various body-related DTCs can pile up, confusing diagnostics— this part clears them efficiently, reducing downtime and repair costs based on real shop scenarios I’ve handled.

Easy Installation Guide
- Provide your vehicle’s VIN during purchase to ensure precise pre-programming for your 2004-2007 Express 3500 with commercial tradesman package (opt PRP).
- Locate the BCM in the center dash area—disconnect the battery first to safely reset any stored codes and avoid shocks.
- Remove the old unit by unplugging connectors and mounting screws; installation typically takes under 5 minutes with basic tools.
- Install the new 15137395 BCM, reconnect everything, and reconnect the battery to power up the system.
- For relearn: If no-start occurs post-install (rare with pre-programming), perform a theft deterrent relearn—insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times. Use an advanced scanner for SDM primary key setup to reset airbag lights.
- Some models may need brake pedal recalibration for optimal safety—consult your manual or a tech if braking feels off. Clear any remaining DTCs with a diagnostic tool to confirm full functionality.
