2007 – 2011 GMC SIERRA 2500 Body Control Module (BCM) 15940214 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with that frustrating moment when your 2007-2011 GMC Sierra 2500’s power windows refuse to budge, or the interior lights flicker unpredictably during a late-night haul? You’re not alone—many truck owners face these headaches from a failing body control module. Questions like “why is my Sierra 2500 airbag light on after electrical glitches?” or “how to resolve intermittent HVAC issues in a 2008 GMC Sierra 2500?” often lead here. This OEM-spec GM BCM, interchangeable with 15940214 and others like 25844480 or 25835966, comes VIN-programmed for seamless integration. It oversees vital systems such as lights, locks, wipers, security, and climate controls, bringing back reliable performance in your heavy-duty pickup. Drawing from over two decades in auto repairs, I’ve seen how a precise replacement like this prevents cascading failures, saving you from costly towing or downtime on job sites. Compatible across GM trucks including Chevrolet Silverado, Suburban, Tahoe, and Cadillac Escalade models from 2007-2013, it ensures your Sierra runs smoothly without dealership visits.

Common Issues & How This Fixes Them

One frequent problem in 2007-2011 GMC Sierra 2500 trucks is erratic HVAC behavior, like the blower motor cutting out randomly. This often stems from degraded BCM circuitry disrupting power signals, leading to uncomfortable drives in extreme weather. Replacing with our VIN-programmed BCM restores consistent climate control, eliminating those intermittent failures. Another issue hits the security system—think false alarms, engine stalling, or no-start conditions due to faulty anti-theft protocols. In my experience, grounding faults exacerbate this, mimicking misfires that confuse diagnostics. This module corrects those by recalibrating communications, clearing DTCs like B1001 without extra tools. Electrical woes, such as dead power windows or non-responsive door locks, trace back to BCM relay degradation over miles of rugged use. Our part fixes this by managing body electronics precisely, preventing shorts that could drain batteries or trigger warning lights. Airbag indicators persisting post-repair? That’s often a mismatch in the supplemental restraint system—our pre-programming aligns it perfectly. For Sierra owners towing heavy loads, these resolutions mean safer, more dependable operation, backed by real-world testing in high-stress scenarios.
