2011 GMC Sierra Denali 1500 Body Control Module (BCM) 15284816 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2011 GMC Sierra Denali 1500 suddenly losing power to the windows during a rainy drive, or the airbag light flashing unexpectedly on a long haul? These frustrating electrical hiccups often stem from a failing body control module, disrupting everything from door locks to HVAC systems. As a seasoned mechanic who’s fixed countless GM trucks, I’ve seen how a faulty BCM can turn a reliable luxury pickup into a headache, especially when towing heavy loads in tough conditions. The solution? Our OEM-spec GM 15284816 BCM, pre-programmed to your exact VIN for seamless integration. This unit restores smooth operation across interior lights, security features, wipers, and more, clearing persistent DTC codes like B1001 without dealership visits. Interchangeable with numbers such as 25844480, 25835966, and others, it fits 2007-2013 GM models including Silverado, Tahoe, Yukon, and Escalade variants. By addressing grounding issues early, you’ll prevent misfires and improve overall towing reliability in your Sierra Denali.
Common Issues & How This Fixes Them
One frequent problem in the 2011 GMC Sierra Denali 1500 involves intermittent HVAC blower failures, where the fan cuts out mid-trip, leaving you sweating or freezing. This often traces back to a degraded BCM struggling with voltage regulation, exacerbated by moisture or wear in high-mileage trucks. Replacing it with our VIN-programmed 15284816 clears related DTCs instantly, ensuring consistent climate control for those extended drives.
Another headache is the airbag warning light triggering DTC B1001, which can sideline your vehicle during inspections. From my experience, this stems from communication breakdowns between the BCM and safety systems, sometimes linked to poor grounds. Our module resolves this by syncing perfectly with your truck’s electronics, preventing false alarms and enhancing safety for family hauls or work sites.
Power windows or door locks failing sporadically? Security malfunctions causing no-starts or stalling? These are classic BCM symptoms, often from internal circuit failures that worsen in cold weather. The 15284816 fixes them by managing body functions reliably, reducing diagnostic headaches and improving daily drivability. I’ve helped owners avoid costly tows by swapping these in under minutes, restoring full functionality and peace of mind.
Grounding problems can mimic BCM faults, leading to misfires or erratic lights. Always inspect connections during replacement to avoid repeatsโour unit’s robust design minimizes these risks, promoting long-term electrical stability.
