2007 – 2010 GMC Sierra Denali Body Control Module (BCM) 15284816 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever hit the road in your 2007-2010 GMC Sierra Denali for a towing job, only to deal with flickering lights or a security system that locks you out? As a seasoned mechanic who’s fixed countless trucks like yours, I’ve seen how a failing body control module can turn a reliable hauler into a headache, especially during heavy-duty tasks. Questions like “why is my Sierra Denali’s airbag light on after starting?” or “how to resolve intermittent HVAC issues in a 2008 GMC truck?” often point straight to the BCM. Our OEM-spec GM BCM, featuring part number 15284816 (interchangeable with 25844480, 25835966, and others), arrives pre-programmed to your VIN for seamless integration. It restores control over lights, locks, windows, wipers, and climate systems in models like the Sierra Denali, Silverado, Tahoe, and Escalade from 2007-2013. This fix not only clears DTC codes but boosts overall electrical stability, enhancing towing reliability in demanding conditions.
Common Issues & How This Fixes Them
From my years in the shop, BCM failures in 2007-2010 Sierra Denali trucks often stem from moisture ingress, voltage spikes, or worn connectorsโcommon in vehicles tackling rough terrain or winter roads. One frequent problem is the airbag warning light triggering DTC B1001, which can sideline your truck due to safety system faults. This module resolves it by recalibrating the serial data module key, preventing false alerts and ensuring compliance during inspections.
Another issue hits HVAC controls, causing erratic blower speeds or total loss of climate functionโimagine sweating through a summer tow or freezing on a cold morning drive. The pre-programmed BCM restores precise management, eliminating intermittent operation tied to faulty grounding. Electrical gremlins like unresponsive power windows, door locks, or exterior lights also plague these models, often linked to security malfunctions that cause stalling or misfires. By addressing these at the source, this replacement clears related DTCs, improves system grounding, and prevents cascading failures, saving you from costly diagnostics.
Security system glitches, including no-start conditions from anti-theft errors, are notorious in Denali trucks used for work. Our BCM integrates the latest GM updates to fix these, offering smoother starts and enhanced theft deterrence without dealership visits.
