2004 – 2007 Chevrolet EXPRESS 1500 BCM (BCM) 15194170 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic power windows in your 2004-2007 Chevrolet Express 1500 that refuse to roll down on a sweltering delivery day, or dashboard lights flickering like a faulty holiday display during rush hour? You’re not alone—I’ve seen countless van owners frustrated by these glitches, often tracing back to a failing Body Control Module. Questions like “Why won’t my Express 1500’s locks engage properly?” or “How do I fix intermittent wiper issues in my 2004 Chevy van?” flood repair forums. The solution? Our pre-programmed BCM, part number 15194170, flashed with the latest GM updates using your VIN for seamless compatibility. It replaces various OEM numbers including 10383536, 15116066, and more, ensuring it fits models like the Express 1500 Van with commercial tradesman package (opt PRP). This isn’t just a swap; it’s a targeted fix that clears DTC codes related to body electronics, restores reliable operation for daily hauls, and enhances overall vehicle stability—drawing from my two decades in diagnostics to prevent recurring headaches.

Common Issues & How This Fixes Them
In my shop experience, a faulty BCM in 2004-2007 Chevrolet Express 1500 vans often manifests as unpredictable electrical behaviors. For instance, you might notice doors not locking automatically, leading to security concerns on job sites—typically caused by degraded internal circuits from moisture exposure or voltage spikes. Another common headache is malfunctioning interior lights that stay on, draining the battery overnight; this stems from corrupted module programming, especially in high-mileage work vans. Then there’s the intermittent horn failure, which could tie into broader communication breakdowns with other modules, risking safety during evasive maneuvers. Replacing with our VIN-specific BCM directly addresses these by restoring proper signal relay, effectively clearing associated DTC codes like those for body control faults. I’ve advised clients facing “no communication with BCM” errors on scanners—swapping to this updated unit not only fixes the immediate problem but also prevents cascading issues, such as erratic climate control in humid weather. For towing enthusiasts using their Express for heavy loads, this module improves reliability by ensuring stable power distribution, reducing downtime. Beyond basics, consider how environmental factors like road salt corrosion accelerate BCM wear; our solution, with fresh GM updates, adds resilience, potentially extending service life in tough commercial use.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—locate the BCM in the center dash for Express models with opt PRP.
- Remove the old module by unplugging connectors and unscrewing mounts; compare part numbers to confirm fit.
- Install the new BCM, reconnecting all wiring securely, then reconnect the battery.
- Perform any necessary relearns: If a no-start occurs, initiate theft deterrent relearn by cycling the key from off to run (without starting) for 10 minutes, three times. Additionally, use a diagnostic tool for ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light.
- Test all functions like lights, locks, and wipers; recalibrate the brake pedal if your vehicle requires it for optimal safety—consult your manual or a pro if unsure.
