2003 – 2006 Cadillac Escalade Body Control Module (BCM) 15116066 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2003-2006 Cadillac Escalade refusing to start on a rainy morning, or the power windows acting up during a family road trip? These frustrating electrical glitches often trace back to a failing body control module, leaving you stranded or dealing with erratic lights and locks. As a seasoned auto repair advisor who’s fixed countless GM vehicles, I’ve seen how a faulty BCM disrupts everything from HVAC to security systems. The solution? Our OEM-quality GM 15116066 BCM, pre-programmed to your exact VIN for seamless plug-and-play installation. This unit restores smooth operation in models like the Escalade, ESV, and EXT, plus Chevrolet Silverado, Tahoe, Suburban; GMC Sierra, Yukon; and even Hummer H2 from 2002-2007. No more dealership visits—get back to reliable driving fast. With this replacement, you’ll clear persistent DTC codes and prevent no-start conditions, enhancing overall vehicle reliability for daily commutes or towing tasks.
Common Issues & How This Fixes Them
Many Escalade owners face intermittent HVAC blower failures, especially in humid conditions common to the 2003-2006 models, where moisture seeps into the BCM causing erratic climate control. This stems from degraded internal circuits, leading to loss of cabin comfort and potential overheating issues. Replacing with our VIN-programmed 15116066 resolves this by recalibrating controls for consistent performance, often clearing related DTCs like B1001 without extra diagnostics. Another headache is the airbag warning light popping on, triggered by BCM communication faults—I’ve diagnosed this in luxury SUVs where it ties into safety systems, risking non-deployment in accidents. Our module fixes it by integrating the latest GM updates, ensuring the SDM primary key setup eliminates the light and restores peace of mind. Electrical woes, such as non-responsive power windows or door locks, frequently arise from grounding problems or security malfunctions, causing no-start scenarios. In real cases, like a client’s Escalade that wouldn’t unlock after a battery drain, swapping the BCM restored full access and prevented theft system lockouts. Various body function DTCs also vanish post-install, improving towing reliability in heavy-duty setups. These fixes not only address symptoms but prevent cascading failures, saving you from costly repairs down the line.
