2010 Chevrolet AVALANCHE 1500 Body Control Module (BCM) 20839063 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 2010 Chevrolet Avalanche 1500 during a long haul, or wondered why your power windows and locks suddenly act up after a rainy drive? These frustrations often stem from a failing Body Control Module (BCM), the central hub managing everything from interior lighting to security systems in your truck. As a seasoned mechanic who’s diagnosed countless GM vehicles, I’ve seen how moisture intrusion or electrical shorts can corrupt the BCM, triggering DTC codes like P0650 or B1370 that disrupt daily drives and even towing tasks. Our pre-programmed BCM, part number 20839063, arrives flashed with the latest GM updates tailored to your VIN, ensuring seamless compatibility and clearing those pesky error codes right away. It matches a wide array of interchangeable numbers including 10382479, 15093910, and more, fitting models like the Tahoe, Yukon, and Express vans from 2006-2013. This isn’t just a replacementโit’s a reliable fix that restores smooth operation, boosts electrical reliability for heavy towing, and prevents future breakdowns, all backed by our one-year warranty with no core charge hassles.
Common Issues & How This Fixes Them
In my years fixing trucks like the 2010 Avalanche 1500, BCM failures often show up as intermittent power accessory problemsโthink doors not locking properly or headlights dimming unexpectedly, especially in harsh weather. A common culprit? Corrosion from water leaks around the under-steering-column mounting, leading to short circuits that throw diagnostic trouble codes (DTCs) and compromise vehicle security. This can escalate to no-start conditions if the anti-theft system glitches, leaving you stranded on a job site. Another frequent headache involves erratic climate control or radio functions, caused by outdated firmware clashing with modern electrical demands, which diminishes overall driving comfort and safety during towing hauls. Our VIN-specific programmed BCM addresses these by integrating the newest GM software updates, effectively clearing DTC codes and recalibrating systems for optimal performance. For instance, I’ve helped owners who noticed improved towing reliability after installation, as the module stabilizes voltage to accessories, preventing power drains that could affect trailer brakes. Plus, it enhances anti-theft protocols without unnecessary relearns unless a no-start pops upโsimple key cycles usually sort that. By tackling root causes like firmware mismatches, this part not only fixes immediate issues but also extends module longevity, saving you from repeated shop visits.
