2013 Chevrolet SILVERADO 3500 Body Control Module (BCM) 15943678 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with frustrating electrical glitches in your 2013 Chevrolet Silverado 3500 that leave you scratching your head? Like when the power windows refuse to budge, or the airbag light stays stubbornly lit, throwing DTC B1001? As a seasoned mechanic who’s fixed countless heavy-duty trucks, I’ve seen owners lose days troubleshooting what turns out to be a failing body control module. This OEM-spec GM BCM, part number 15943678, comes VIN-programmed for seamless integration, managing everything from lights and locks to HVAC and security. It fits 2007-2013 GM vehicles, including Chevrolet Silverado series, Suburban, Tahoe; GMC Sierra, Yukon; and Cadillac Escalade models. Swapping in this module restores reliable performance, cutting down on diagnostic headaches and getting your rig back on the job site or highway without dealership visits.
Common Issues & How This Fixes Them
One frequent headache with a deteriorating BCM in your 2013 Silverado 3500 is erratic HVAC behaviorโthink blower motors that cut out randomly or controls that ignore your inputs. This often stems from internal circuit failures, exacerbated by moisture or voltage spikes common in work trucks hauling loads through rough weather. Replacing with our pre-programmed 15943678 resolves this by recalibrating the system’s electronics, ensuring consistent climate control.
Another telltale sign? The airbag warning light flashing with codes like DTC B1001, signaling communication breakdowns that could compromise safety. From my experience, this ties back to corrupted module data, especially after battery issues. Our VIN-matched BCM clears these codes instantly, preventing false alarms and restoring peace of mind during long hauls.
Don’t overlook security system woes, such as random stalling or door locks that fail to respond, often linked to grounding problems or misfires. I’ve diagnosed these in fleet vehicles where wear from daily use builds up. This module’s robust design fixes grounding inconsistencies, enhances security protocols, and eliminates intermittent electrical failures like non-functional lights or wipers. By addressing root causes with precise programming, it prevents cascading issues, saving you from expensive tow bills or downtime.
