2004 – 2007 Chevrolet EXPRESS 1500 BCM (BCM) 15137393 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering during a long delivery run in your 2004-2007 Chevrolet Express 1500, or wondered why your power locks suddenly fail on a rainy workday? These frustrating symptoms often stem from a failing Body Control Module (BCM), disrupting everything from interior lighting to security systems in GM vans and trucks. As a seasoned mechanic who’s diagnosed countless electrical gremlins in workhorses like the Express 1500, I know how a faulty BCM can sideline your vehicle, leading to downtime and safety concerns. Our pre-programmed BCM, part number 15137393, arrives ready-to-install with the latest GM software updates tailored to your VIN, ensuring seamless integration. It replaces various OEM numbers like 10383536, 15116066, and others, restoring reliable operation. This fix not only clears persistent DTC codes related to body electronics but also enhances overall system stability, preventing issues like intermittent wiper failures or alarm malfunctions that plague older GM models during heavy use.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, I’ve seen BCM failures manifest in ways that baffle owners. For instance, in a 2004-2007 Express 1500 used for tradesman duties, you might notice doors not locking remotely, headlights dimming unexpectedly, or the security system triggering false alarms—often due to corroded circuits or outdated software in the original module. These stem from exposure to moisture, vibrations from rough roads, or electrical overloads, which can throw DTC codes like U0140 or B1370, halting operations. Another common headache: intermittent power window operation or radio glitches, especially in humid climates, caused by the BCM’s role in managing body electronics. Replacing with our VIN-specific BCM resolves these by refreshing the control logic, clearing error codes, and restoring smooth communication between systems. Take a real case—a delivery driver whose van’s interior lights stayed on, draining the battery overnight; a new BCM fixed it, improving fuel efficiency and reliability for daily routes. This approach not only addresses root causes but also boosts safety features like proper airbag deployment signals, making it essential for vehicles with high uptime needs.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety, then locate the BCM—typically in the center dash for Express vans with commercial tradesman package (opt PRP).
- Remove the old module by unplugging connectors and unbolting it carefully, avoiding damage to surrounding wiring.
- Install the new BCM in the same position, reconnecting all plugs securely.
- Reconnect the battery and perform any necessary relearns: If a no-start condition occurs, conduct a theft deterrent relearn by cycling the key from off to run (without starting) for 10 minutes, three times.
- Test all functions like lights, locks, and accessories to confirm operation.
