2002 – 2006 GM AVALANCHE 2500 Body Control Module (BCM) 15116066 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic power windows that refuse to budge on a rainy day in your 2002-2006 GM Avalanche 2500, or wondered why your door locks act up during a long haul? These frustrations often trace back to a failing body control module, disrupting everything from lights to security systems. As a seasoned mechanic who’s fixed countless GM trucks, I’ve seen how a faulty BCM can turn a reliable Avalanche into a headache, especially when towing heavy loads in tough weather. The solution? Our OEM-spec GM 15116066 BCM, pre-programmed to your exact VIN for seamless integration. This plug-and-play unit restores smooth operation across interior/exterior lights, power windows, door locks, wipers, HVAC, and more, clearing persistent DTC codes like B1001 without dealership visits. Compatible with your Avalanche 2500 and extending to models like Chevrolet Silverado, Suburban, Tahoe; GMC Sierra, Yukon; Cadillac Escalade; and Hummer H2 from 2002-2007. It not only fixes immediate issues but enhances overall electrical reliability, improving towing stability by ensuring consistent accessory performance under load.
Common Issues & How This Fixes Them
One frequent headache in 2002-2006 GM Avalanche 2500 trucks is intermittent HVAC blower operation, often caused by degraded BCM circuitry from moisture exposure or age-related wear. This leads to uncomfortable cabins during extreme weather, and it might trigger airbag warning lights with codes like B1001, signaling communication breakdowns. Another common problem: non-functional power windows or door locks, stemming from BCM grounding issues that escalate to security malfunctions or no-start conditions. In my experience, these symptoms worsen in high-mileage vehicles used for towing, where electrical strain amplifies failures. Replacing with our VIN-programmed 15116066 BCM resolves these by recalibrating body electronics, clearing DTCs automatically, and preventing future glitches. For instance, a client with a Sierra 2500 hauling trailers reported resolved no-start issues post-replacement, restoring confidence for daily drives. It also tackles wiper inconsistencies, ensuring visibility in storms, and improves security system reliability to avoid theft-related headaches.
