2003 – 2007 Chevrolet SILVERADO 1500 BCM (BCM) 15137393 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with that frustrating moment when your 2005 Chevy Silverado 1500’s interior lights flicker erratically during a rainy drive home, or the power locks refuse to respond, leaving you questioning if it’s a simple fuse or something deeper? As a seasoned mechanic who’s tackled countless BCM failures in GM trucks, I’ve seen how these issues disrupt daily routines—especially for folks relying on their Silverado for work hauls or family trips. The culprit? A faulty Body Control Module (BCM) that’s central to managing electrical systems like windows, doors, and alarms. Our pre-programmed BCM, part number 15137393, directly addresses this by arriving flashed with the latest GM updates tailored to your VIN. It replaces a range of OEM numbers including 10383536, 15116066, 15136225, 15136877, 15137394, 15137395, 15137396, 15198116, 15257043, 15257044, 15257045, 15257046, 10367690, 15064149, and 15194170. Beyond fixing symptoms, it clears persistent DTC codes related to body electronics, restoring smooth operation and even enhancing overall vehicle reliability for tasks like towing heavy loads without random electrical glitches.

Common Issues & How This Fixes Them
In my years fixing GM trucks, I’ve encountered owners frustrated by “why won’t my 2004 Silverado 1500 doors lock properly?” Often, it’s the BCM failing due to moisture ingress or voltage spikes from worn batteries, causing erratic behaviors like non-responsive power windows or random dashboard warnings. Another common headache is intermittent interior lighting that dims unexpectedly, linked to BCM communication breakdowns with the vehicle’s network—exacerbated in harsh weather common to 2003-2007 models. This not only affects comfort but can lead to safety risks, such as malfunctioning turn signals during towing. Replacing with our VIN-matched BCM resolves these by recalibrating the system’s core logic, effectively clearing DTC codes like B1370 or U0140 that signal module faults. For instance, a client with a 2006 Silverado reported improved towing reliability after install, as the new module stabilized power distribution to trailer brakes and lights. Don’t overlook subtle signs like delayed remote start; early BCM replacement prevents escalation to full electrical failures, saving on broader repairs. Through real diagnostics, I’ve found that addressing root causes like corroded connectors alongside the swap yields long-term fixes, empowering you to troubleshoot confidently.
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, then locate the BCM under the steering column in your Silverado 1500 (or center dash in compatible vans).
- Remove the old module by unplugging connectors and unbolting it—note any corrosion for cleaning to prevent future issues.
- Install the new BCM, reconnect everything securely, and reconnect the battery.
- Perform post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is needed for optimal safety.
- If a no-start condition occurs (indicating theft deterrent activation), conduct a simple theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times—consult your manual or a pro if variances apply.
