2007 – 2011 GM – Body Control Module (BCM) 15263497 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your GMC Sierra 3500’s power windows refusing to budge or the HVAC system acting up unpredictably during a long haul? You’re not alone—many owners of 2007-2011 GM trucks like the Sierra 1500, 2500, or 3500 face these frustrating electrical gremlins when the body control module starts failing. What if replacing it could restore seamless control over lights, locks, and climate without a trip to the dealer? Enter the GM 15263497 BCM, a direct OEM replacement pre-programmed to your exact VIN for effortless plug-and-play fitment. This module oversees vital systems like door locks, wipers, security, and interior lighting in vehicles such as Chevrolet Silverado, Tahoe, Suburban, and Cadillac Escalade models from that era. Interchangeable with numbers like 25844480, 25835966, and others, it ensures compatibility across GM’s lineup. Drawing from over two decades in auto repairs, I’ve seen how a faulty BCM can cascade into bigger issues like security lockouts or erratic blower motors—replacing it not only fixes symptoms but prevents costly downstream failures by stabilizing the vehicle’s electrical network.

Common Issues & How This Fixes Them
A failing BCM in 2007-2011 GM vehicles often shows up as subtle but aggravating problems. For instance, you might notice intermittent HVAC blower operation, where the fan works one minute and quits the next—typically due to degraded internal circuits losing communication with climate controls. Another red flag is the airbag warning light illuminating with codes like DTC B1001, stemming from faulty sensor integration that this pre-programmed replacement recalibrates instantly. Electrical glitches, such as non-responsive power windows or door locks, arise from corroded connections or software glitches, disrupting daily use in trucks like the Silverado 2500. Security system failures can even cause stalling or no-start conditions, often linked to poor grounding; I’ve diagnosed these in Sierra Denali models where moisture infiltration accelerates wear. Various body-related DTCs compound the frustration, leading to misfires or wiper malfunctions. Swapping in the 15263497 BCM addresses these at the source by restoring stable voltage distribution and module communication, preventing escalations like battery drain. From my experience, checking harness integrity during replacement avoids repeats, saving owners time and money on unnecessary scans.
Easy Installation Guide
- Provide your VIN during purchase to ensure the module arrives pre-programmed for your specific 2007-2011 GM vehicle.
- Locate the BCM under the steering column or dashboard—disconnect the battery first for safety to prevent electrical shorts.
- Remove the old module by unplugging connectors and unbolting it; inspect for any grounding issues like corrosion that could cause ongoing problems.
- Install the new 15263497 BCM, reconnecting all plugs securely— the process usually takes less than five minutes with basic tools.
- After installation, if an airbag light persists (e.g., DTC B1001), use a diagnostic scanner to perform the ‘Setup SDM Primary Key in BCM’ procedure under special functions.
- For theft relearn (only if no-start occurs): Cycle the key from off to on 10 times, waiting 10 minutes each cycle if needed; some models may also require brake pedal recalibration for optimal safety—consult your manual or a tech if unsure.
