2013 GMC SIERRA 3500 Body Control Module (BCM) 15284816 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your 2013 GMC Sierra 3500 suddenly losing power to the windows during a heavy tow haul, or the security system kicking in at the worst moment on a job site? As a seasoned mechanic who’s seen countless heavy-duty trucks like yours battle electrical gremlins, I know how frustrating it can be when body functions fail mid-drive. That’s where this OEM-spec GM BCM, part number 15284816, steps in—pre-programmed to your exact VIN for seamless integration. It restores control over lights, locks, wipers, HVAC, and more, clearing stubborn DTC codes like B1001 without dealership visits. Compatible across 2007-2013 GM lineup, including Silverado, Tahoe, Yukon, and Escalade models, this module ensures your Sierra 3500 handles towing reliability and daily demands effortlessly. Drawing from years of diagnostics, I’ve watched owners regain confidence on rugged terrains after swapping in a unit like this—it’s not just a fix; it’s peace of mind for those long hauls.

Common Issues & How This Fixes Them

One frequent headache in the 2013 GMC Sierra 3500 involves intermittent HVAC blower failures, often triggered by a degraded BCM struggling with voltage fluctuations during extreme weather or heavy loads. This can leave you sweating on summer tows or freezing in winter drives, potentially linked to grounding issues that exacerbate DTCs. Another common sign is the airbag warning light flashing with codes like B1001, stemming from communication breakdowns that compromise safety systems—I’ve diagnosed this in trucks where moisture ingress corroded connections, leading to erratic behavior.

Power windows or door locks refusing to budge? That’s typically a BCM relay fault, causing frustration when accessing your cab after a muddy job. Security malfunctions might even result in no-starts or stalling, mimicking fuel issues but rooted in anti-theft protocols gone haywire. In my shop experience, these stem from aging modules overwhelmed by the Sierra’s robust electrical demands, especially in towing scenarios.

Swapping to this pre-programmed 15284816 BCM resolves these by recalibrating body electronics precisely to your VIN, clearing DTC codes and preventing recurrences. It enhances overall system stability, improving towing reliability by ensuring consistent power distribution—no more surprises on the highway.
