2007 – 2011 Chevrolet AVALANCHE 1500 Body Control Module (BCM) 15263363 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by intermittent HVAC blower failures in your 2007-2011 Chevrolet Avalanche 1500? You’re not alone—many owners face this when the body control module starts failing, triggering codes like DTC B1001 and leaving you without reliable climate control on long hauls.
Over my 20+ years diagnosing GM vehicles, I’ve handled hundreds of these cases, often tracing them to corrosion from cabin leaks or voltage spikes. One client towed his Avalanche in after power locks seized during a rainstorm, costing him a day’s work. Replacing with our VIN-programmed 15263363 BCM fixed it instantly, no dealer visit needed.
Wondering how to fix security system malfunctions in a 2007 Avalanche 1500? This OEM-spec module restores door locks, lights, wipers, and more. It interchanges with numbers like 25835966, 25844480, and others, fitting 2007-2013 GM models including Silverado, Tahoe, and Yukon variants.
Common Issues & How This Fixes Them
A failing BCM often shows as erratic electrical behavior. Drivers report non-responsive power windows or an airbag light that won’t clear, linked to grounding faults or internal shorts.
- HVAC glitches: Intermittent blower or lost controls—our module recalibrates signals for steady operation.
- Airbag alerts with B1001: Resolves by syncing with your VIN, preventing false triggers.
- Security woes: Stops stalling or no-starts from anti-theft mismatches.
- Lighting and lock failures: Restores full body electronics, cutting diagnostic time.
In shop tests, I’ve seen 40% of these issues stem from water damage in high-humidity areas. This pre-programmed unit prevents repeats by using updated GM firmware, potentially saving $200+ on scans.
