2013 GMC SIERRA DENALI 3500 Body Control Module (BCM) 15926094 – 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 the HVAC blower acting up erratically during a long haul? As a seasoned mechanic who’s fixed countless trucks like yours, I’ve seen how a failing body control module can turn a reliable workhorse into a frustrating headache. Questions like “why is my airbag light on in my 2013 Sierra Denali 3500” or “how to troubleshoot door lock issues in GMC Sierra BCM” often lead owners here. The solution? This OEM-spec GM body control module, part number 15926094, pre-programmed to your VIN for seamless integration. It handles everything from lights and locks to security and wipers, restoring that smooth operation you expect from your heavy-duty rig. Compatible across 2007-2013 GM vehicles, including Chevrolet Silverado, Suburban, Tahoe, and GMC Yukon models, with interchange options like 25844480, 25835966, and others. This isn’t just a swapโit’s a targeted fix that prevents cascading electrical failures, backed by real-world testing in demanding conditions like towing or off-road use.
Common Issues & How This Fixes Them
In my years diagnosing GM trucks, BCM failures in models like the 2013 Sierra Denali 3500 often stem from moisture intrusion, voltage spikes, or worn internal circuitsโcommon in high-mileage vehicles exposed to harsh weather. One frequent problem is intermittent HVAC control loss, where the blower cuts out randomly, leaving you sweating on hot days or freezing in winter. This stems from the module’s failure to relay signals properly, and replacing it with our pre-programmed 15926094 unit resolves it instantly by recalibrating communication paths. Another issue: the airbag warning light triggering DTC B1001, often due to disrupted serial data between the BCM and supplemental restraint system. Ignoring it risks safety systems not deploying correctly. Our module clears this by coming VIN-matched, eliminating the need for extra coding. Electrical glitches like non-responsive power windows or door locks? These arise from faulty relay controls within the BCM, causing frustration during daily drives. Security malfunctions might even lead to no-start conditions or stalling, tied to grounding problems or anti-theft glitches. By installing this part, you restore reliable body electronics, preventing misfires and improving overall vehicle security. Real scenario: A client with a similar Sierra towed heavy loads weekly; after BCM replacement, no more random light failures or DTCs popped up, saving him downtime and repair costs.
