2013 GMC Sierra Denali 3500 Body Control Module (BCM) 22860591 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your 2013 GMC Sierra Denali 3500 suddenly losing power to the windows or lights flickering unpredictably on a long haul? Maybe you’ve asked yourself, “Why is my truck’s security system acting up, triggering random alarms or preventing starts?” These frustrations often trace back to a failing body control module, disrupting everything from HVAC to door locks. As a seasoned mechanic who’s fixed countless GM trucks, I’ve seen how a bad BCM can turn a reliable workhorse into a headache. Enter the GM 22860591 BCM, a direct OEM replacement pre-programmed to your exact VIN for seamless integration. This unit restores control over interior lighting, wipers, security features, and more, fitting 2007-2013 GM models like the Sierra series, Silverado pickups, Yukon SUVs, and Escalade variants. Boldly interchangeable with numbers such as 22860591, 25835966, and others, it ensures compatibility without guesswork. Beyond basic fixes, this module enhances overall electrical stability, preventing cascading failures in demanding conditions like towing or off-road use.

Common Issues & How This Fixes Them

In my years diagnosing GM vehicles, common BCM failures in a 2013 GMC Sierra Denali 3500 often show as erratic HVAC behavior, where the blower fan cuts out intermittently or controls refuse to respond—usually due to corroded circuits or software glitches from age and exposure. Another red flag is the airbag warning light illuminating with codes like DTC B1001, stemming from communication breakdowns between modules. Electrical gremlins, such as power windows that won’t budge or door locks failing to engage, point to internal relay issues, while security malfunctions can cause no-starts, stalling, or even misfires tied to grounding faults. These problems not only strand you but also risk safety on the road. Replacing with our VIN-programmed 22860591 BCM resolves them by recalibrating body electronics precisely to your truck’s specs, clearing codes and restoring smooth operation. For instance, in a real shop scenario, a client with a Sierra hauling heavy loads fixed persistent lighting issues post-replacement, avoiding costly downtime. Expert tip: Scan for underlying wiring damage first to prevent repeats, as moisture ingress often accelerates BCM wear in trucks like yours.
