2013 Chevrolet SILVERADO 2500 Body Control Module (BCM) 15943678 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2013 Chevrolet Silverado 2500 suddenly losing power to the windows or the HVAC fan acting up on a hot day? Or maybe you’ve asked yourself, “Why is my Silverado 2500 airbag light on with DTC B1001 after some electrical glitches?” These frustrations often point to a failing body control module, disrupting everything from lights to security systems. Swap it out with this OEM-spec GM BCM, part number 15943678, pre-programmed to your VIN for seamless integration. It fits 2007-2013 GM trucks and SUVs like the Silverado 2500, Sierra 2500, Tahoe, Yukon, and Escalade models, interchangeable with numbers such as 25844480, 25835966, and others. This isn’t just a fixโit’s a restoration of reliable performance, drawing on the latest GM software updates to eliminate persistent codes and grounding woes right away.
Common Issues & How This Fixes Them
In my two decades fixing trucks like the 2013 Silverado 2500, I’ve seen BCM failures mimic a domino effect of electrical chaos. Take intermittent HVAC blower operation: it often stems from degraded internal circuits in the module, causing erratic fan speeds or total loss of climate control during long hauls. This pre-programmed BCM restores steady signals, ensuring your cab stays comfortable without the guesswork.
Another headache is the airbag warning light triggering DTC B1001. This code signals a communication breakdown between the BCM and the supplemental restraint system, potentially from corrosion or voltage spikes. Installing this VIN-matched unit resolves it by syncing perfectly, preventing safety risks on rough roads. Electrical gremlins like dead power windows, unresponsive door locks, or flickering lights? They’re usually tied to faulty relays inside the old moduleโour replacement handles these with enhanced circuitry for consistent operation.
Security system malfunctions can lead to no-starts or stalling, often misdiagnosed as fuel issues. In one case, a Silverado owner chased misfires for weeks before realizing BCM grounding problems were the culprit. This module fixes that by optimizing anti-theft protocols and stabilizing engine communications. Plus, it clears various body-related DTCs, saving you diagnostic fees.
