2013 GMC SIERRA DENALI 2500 Body Control Module (BCM) 15263497 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with that frustrating moment when your 2013 GMC Sierra Denali 2500’s power windows refuse to budge, or the door locks act up right before a long haul? You’re not alone—I’ve seen countless truck owners pull into the shop with these electrical gremlins, often tracing back to a failing body control module. Questions like “why is my Sierra’s HVAC blower intermittent?” or “how to clear DTC B1001 on a 2013 GMC Sierra Denali 2500” flood forums, pointing to BCM woes that disrupt everything from lights to security systems. Enter the solution: our OEM-spec GM BCM, interchangeable with 15263497 and others like 25844480 or 25835966, pre-programmed to your VIN for seamless fit in 2007-2013 GM vehicles. This module oversees interior/exterior lighting, wipers, HVAC, and more, restoring reliability for towing or daily drives. Compatible across Chevrolet Silverado, Suburban, Tahoe; GMC Yukon, Sierra models including your Denali 2500; and Cadillac Escalade variants, it clears persistent DTC codes and boosts overall electrical stability without dealership visits.

Common Issues & How This Fixes Them

A malfunctioning BCM in your 2013 GMC Sierra Denali 2500 can turn a reliable workhorse into a headache. Take intermittent HVAC blower operation—often caused by degraded internal circuits failing to relay signals, leaving you sweating on hot days or freezing in winter hauls. This pre-programmed BCM resolves it by reinstating precise control over climate systems, ensuring consistent airflow and temperature regulation. Then there’s the airbag warning light with DTC B1001, triggered by communication breakdowns between modules; ignoring it risks safety during off-road adventures or heavy towing. Our unit clears these codes instantly upon install, thanks to VIN-specific programming that aligns with GM’s latest updates. Electrical glitches like non-responsive power windows, door locks, or lights stem from grounding issues or worn relays—common in high-mileage trucks exposed to rough conditions. Replacing with this BCM eliminates them, preventing stalling or security malfunctions that could strand you. In real scenarios, like a fleet owner I advised whose Sierra misfired during deliveries, this fix not only restored functions but improved towing reliability by stabilizing electronics. It also addresses various body-related DTCs, reducing diagnostic time and avoiding costly repeats—empowering you to troubleshoot effectively with a scanner for long-term peace of mind.

2. Locate the module under the steering column or dash—disconnect the battery first for safety to avoid electrical shorts.
3. Remove the old BCM by unplugging connectors and unbolting it; inspect for grounding problems like corrosion that could cause recurring issues.
4. Install the new unit, reconnect everything securely, and reconnect the battery—expect a quick 5-minute process for most DIYers.
5. After installation, if the airbag warning persists, use a diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to reset it and ensure safety features align.
6. For theft relearn (only if no-start occurs): Cycle the key from off to on 10 times, waiting 10 minutes per cycle if needed; some may require brake pedal recalibration for optimal braking—consult your manual or a pro if unsure.
