2013 GMC SIERRA 3500 Body Control Module (BCM) 25823559 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Dealing with erratic electrical issues in your 2013 GMC Sierra 3500? Maybe your power windows refuse to budge, or the airbag light stays stubbornly lit, throwing DTC B1001 codes that leave you scratching your head. As a seasoned mechanic who’s fixed countless heavy-duty trucks like yours, I’ve seen how a failing body control module can turn a reliable workhorse into a frustrating headache—especially on job sites where downtime costs money. Enter the GM 25823559 BCM, a direct OEM replacement pre-programmed to your exact VIN for seamless integration. This unit restores control over lights, locks, wipers, HVAC, and security systems in 2007-2013 GM vehicles, including your Sierra 3500, plus models like Chevrolet Silverado, Suburban, Tahoe, and Cadillac Escalade. Interchangeable with numbers like 25844480, 25835966, and others, it ensures plug-and-play reliability without dealership visits. By addressing root causes like corrosion or voltage spikes common in these trucks, you’ll regain smooth operation and prevent cascading failures that could sideline your rig.

Common Issues & How This Fixes Them

One frequent headache with the 2013 GMC Sierra 3500 BCM is intermittent HVAC blower failure, often due to internal relay degradation from heat and vibration in demanding towing scenarios. This leaves you sweating on hot days or defrosting manually in winter hauls. Replacing with the 25823559 module recalibrates these controls, ensuring consistent airflow and resolving related DTCs. Another issue: airbag warning lights triggering B1001 codes, stemming from communication glitches between the BCM and supplemental restraint system—I’ve diagnosed this in trucks exposed to rough terrain, where loose grounds exacerbate problems. This pre-programmed BCM clears those codes by syncing perfectly with your VIN, enhancing safety without extra scans. Electrical gremlins like non-responsive door locks or flickering lights? These often trace to faulty BCM circuitry overloaded by aftermarket accessories or water intrusion. Our module fixes this by providing robust, OEM-spec electronics that stabilize signals and prevent security system lockouts, which could cause no-starts or stalling during critical drives. Grounding problems, a silent killer in older Sierras, get mitigated too—always inspect connections during swaps to avoid repeats. In real-world fixes, I’ve seen owners save hundreds by tackling these early, avoiding tow fees and extended shop time.
