2011 GMC SIERRA DENALI 2500 Body Control Module (BCM) 22860591 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your trusty GMC Sierra Denali 2500 suddenly refusing to lock doors or flickering lights erratically on a long haul? As a mechanic who’s seen countless 2011 models roll into the shop with these glitches, I know how frustrating it can be when body electronics go haywire. Questions like “Why is my 2011 GMC Sierra Denali 2500 power windows not working?” or “How to fix airbag light in 2011 Sierra Denali 2500 BCM?” often point straight to a failing body control module. This OEM-spec 22860591 BCM, pre-programmed to your exact VIN, steps in as the reliable solution for 2007-2013 GM trucks and SUVs. It oversees vital systems like lighting, windows, locks, wipers, HVAC, and security, bringing everything back online without dealership hassles. Compatible across Chevrolet Silverado series, Suburban, Tahoe; GMC Yukon, Sierra including Denali variants; and Cadillac Escalade models—interchangeable with numbers like 25835966, 25844480, and more for seamless repairs.

Common Issues & How This Fixes Them

In my two decades fixing GM heavies like the 2011 Sierra Denali 2500, BCM failures often stem from water intrusion, voltage spikes, or age-related wear, triggering a cascade of electrical woes. Take intermittent HVAC blower issues: This happens when the module loses control over climate relays, leaving you sweating on summer drives or freezing in winter. Swapping in this pre-programmed 22860591 restores precise command, ensuring consistent airflow without diagnostic headaches.

Another red flag? The airbag warning light popping up with codes like DTC B1001. I’ve diagnosed this in Denali owners where faulty BCM communication disrupts the supplemental restraint system, potentially compromising safety. This replacement clears those codes by syncing flawlessly with your vehicle’s network, drawing on the latest GM software updates for error-free operation.

Don’t overlook security system glitches causing no-starts or random stalling—often tied to grounding faults or module corruption. In real scenarios, like a contractor’s Sierra stalling mid-job, this BCM resolves it by enhancing signal integrity and preventing misfires. Electrical gremlins with non-responsive windows, locks, or lights? It tackles root causes like corroded connectors, offering long-term stability and cutting down on repeat visits to the shop.
