2013 GMC SIERRA 3500 Body Control Module (BCM) 15263363 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2013 GMC Sierra 3500 suddenly losing power to the windows or the HVAC system acting up out of nowhere? You’re not aloneโI’ve seen countless truck owners pull into the shop frustrated by these glitches, wondering “why is my Sierra 3500 door locks not working?” or “how to fix airbag light in 2013 GMC Sierra 3500.” Often, the culprit is a failing body control module, disrupting everything from lights to security features. That’s where this OEM-spec GM BCM, part number 15263363 (interchangeable with 25844480 and others like 25835966), comes in. Pre-programmed to your exact VIN, it fits seamlessly into 2007-2013 GM vehicles, including your Sierra 3500, restoring smooth operation without dealership hassles. Drawing from years of diagnostics, I’ve found this fix not only clears pesky DTCs but prevents cascading electrical failures, saving you time and money on repeated repairs.
Common Issues & How This Fixes Them
In my experience working on heavy-duty trucks like the 2013 GMC Sierra 3500, a faulty BCM often shows up as erratic HVAC behaviorโthink blower fans that cut out intermittently or total loss of climate controls during a long haul. This stems from degraded internal circuits failing to relay signals properly, leading to discomfort on the road. Another red flag? The airbag warning light popping on with codes like DTC B1001, which can signal communication breakdowns between the BCM and safety systems, potentially compromising your drive. Electrical gremlins, such as unresponsive power windows, door locks that won’t engage, or flickering interior lights, point to the same issueโcorroded connections or software glitches in the module. Security system woes, including false alarms or engine stalling due to grounding faults, add to the headache, sometimes mimicking misfires. Various body-related DTCs round out the symptoms, often traced back to moisture intrusion or age in these workhorse vehicles. Replacing with this VIN-programmed BCM resolves these by recalibrating all body electronics, ensuring reliable performance. For instance, I once helped a Sierra owner who thought his truck’s wiper issues were wiring-related; swapping the module fixed it instantly, highlighting how a targeted replacement beats guesswork.
