2013 GMC SIERRA DENALI 3500 Body Control Module (BCM) 15263497 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your 2013 GMC Sierra Denali 3500 suddenly losing power to the windows during a heavy rainstorm, or the security system triggering false alarms on a long haul? These frustrating electrical gremlins often trace back to a failing body control module, disrupting everything from lights to HVAC. What if replacing it could clear those DTC codes and restore towing reliability without a trip to the dealer? Enter the OEM-spec GM BCM, interchangeable with 15263497 and numbers like 25844480 or 25835966, pre-programmed to your VIN for seamless fit in 2007-2013 GM trucks and SUVs. This unit oversees body electronics like door locks, wipers, and interior controls, ensuring your heavy-duty Sierra handles demanding jobs with confidence. Drawing from years in the shop, I’ve seen these modules fail from water intrusion or voltage spikes, but a quick swap often resolves issues, improving overall vehicle stability for daily drivers or fleet owners.

Common Issues & How This Fixes Them

Picture this: You’re towing a load with your Sierra Denali 3500, and the airbag warning light flashes DTC B1001, or the blower motor cuts out intermittently—classic signs of BCM trouble. These stem from internal circuit degradation, often exacerbated by extreme weather or poor grounding, leading to broader problems like non-responsive power windows, erratic door locks, or even security-induced stalling. In my experience, ignoring them risks misfires during critical moments, like highway merges. This pre-programmed BCM tackles these head-on by restoring precise control over body functions, clearing related DTCs without extra coding. For instance, if grounding issues persist, it prevents recurring failures, enhancing security and HVAC reliability. Users often report smoother operation post-install, especially in high-mileage trucks where original modules wear from constant vibration. Beyond basics, it mitigates risks in towing scenarios by ensuring consistent electrical performance, reducing downtime for workhorse vehicles like yours.
