2011 GMC SIERRA DENALI 2500 Body Control Module (BCM) 15263363 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by flickering lights or unresponsive door locks in your 2011 GMC Sierra Denali 2500? These glitches often point to a failing body control module, disrupting everything from security systems to HVAC operation. In my 20+ years diagnosing GM trucks, I’ve pinpointed over 300 BCM issues tied to electrical shorts from rough off-road use or age-related wear. Replacing with our VIN-programmed 15263363 BCM restores seamless control over lights, windows, locks, wipers, and more. This OEM-spec unit fits 2007-2013 GM models like the Sierra series, Silverado, Tahoe, Yukon, and Escalade, and interchanges with numbers including 25844480, 25835966, and others. It eliminates dealership trips, saving you $200+ in programming fees while preventing recurring DTCs like B1001.
Common Issues & How This Fixes Them
Body control module problems hit hard in heavy-duty trucks like the Sierra Denali 2500, especially during towing or winter drives. Drivers frequently ask, “Why does my airbag light stay on in my 2011 GMC Sierra?” or “How to troubleshoot intermittent HVAC blower in Sierra Denali 2500?” Based on shop data, about 40% of these stem from grounding faults or moisture damage, leading to stalling, misfires, or non-functional accessories.
- Intermittent HVAC or blower failure: The new BCM recalibrates controls, ensuring consistent climate performance without erratic operation.
- Airbag warning with DTC B1001: Pre-programming resolves communication errors, clearing codes that plague older modules.
- Power window/lock malfunctions: Restores reliable electronics, fixing shorts that cause random failures.
- Security system glitches or engine stalling: Enhances anti-theft protocols, preventing no-start issues from faulty signals.
- Various body-related DTCs: Analyzes and corrects underlying electrical anomalies for long-term stability.
From real cases, one Sierra owner towing heavy loads reported total light failure mid-haul—our BCM swap fixed it in minutes, avoiding roadside hazards.

Pro Tip: Pair this with a ground wire inspection to extend module life, especially in high-mileage trucks exposed to salt or mud.
Easy Installation Guide
Swapping the BCM under the steering column takes under five minutes with basic tools. Disconnect the battery first to avoid shorts. After install, if no-start occurs, perform a simple theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds—repeat three times. For persistent airbag lights, use a scan tool for the ‘Setup SDM Primary Key in BCM’ procedure. Some Sierra models need brake pedal recalibration—depress fully 10 times with ignition on. Check grounds to prevent repeats. Consult your manual or a pro if unsure; no core charge means you keep the old part.
Real Customer Story: A contractor with a 2011 Sierra Denali fixed his window issues post-install, noting, “Back to work without downtime—programming was spot-on.”
