Ever dealt with your 2013 GMC Sierra 3500 suddenly losing power to the windows or the HVAC blower acting up during a long haul?

Compatible across 2007-2013 GM lineup, including Chevrolet Silverado, Suburban, Tahoe, and GMC Yukon models, it clears persistent DTCs like B1001 and boosts overall electrical stability. Drawing from years in the shop, I’ve seen this swap prevent breakdowns on job sites, saving owners time and money while enhancing safety for daily drives or rugged use.

Common Issues & How This Fixes Them

In a workhorse like the 2013 GMC Sierra 3500, a faulty BCM can trigger a cascade of problems, especially under heavy loads or harsh weather. One frequent headache is intermittent HVAC operation—think blower motors cutting out mid-trip, often due to degraded internal circuits failing to relay signals properly. This not only affects comfort but can lead to foggy windows impairing visibility during rain or snow. Another common sign? The airbag warning light illuminating with DTC B1001, pointing to communication breakdowns between the BCM and supplemental restraint system, potentially compromising safety in collisions. Electrical gremlins, such as unresponsive power windows, door locks, or exterior lights, arise from corrosion or voltage spikes, common in trucks exposed to off-road conditions. Security malfunctions might cause no-starts or erratic stalling, mimicking engine issues but rooted in BCM grounding faults. Replacing with this pre-programmed 15263497 BCM resolves these by reestablishing stable connections, clearing codes automatically, and improving system reliability. From my experience, it also prevents misfires tied to poor grounding, ensuring smoother performance for towing trailers or hauling gear—ultimately reducing diagnostic headaches and extending vehicle life.

Easy Installation Guide

1. Provide your VIN during purchase to ensure precise programming tailored to your 2013 GMC Sierra 3500.
2. Locate the BCM under the steering column—disconnect the battery first for safety to avoid electrical shorts.
3. Remove the old module by unplugging connectors and unbolting it, inspecting for any grounding issues like corroded wires that could cause repeats.
4. Install the new BCM, reconnect everything securely, and reconnect the battery.
5. Perform a quick test of functions like lights and locks; if no-start occurs, initiate theft relearn by cycling the key from off to run (without starting) 3-4 times, waiting 10 minutes each cycle until the security light turns off.
