2007 – 2011 GMC YUKON XL 2500 Body Control Module (BCM) 20939138 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2007-2011 GMC Yukon XL 2500 acting up on a long haul, where the power windows refuse to budge, or the security system locks you out unexpectedly? You’re not aloneโI’ve seen this countless times in my shop, often tracing back to a failing body control module. Questions like “why is my Yukon XL 2500 HVAC blower intermittent?” or “how to fix airbag warning light in 2007 GMC Yukon XL 2500” flood my inbox. The culprit? A worn-out BCM struggling with electrical demands in these heavy-duty SUVs. Enter the GM 20939138 BCM, a direct OEM replacement pre-programmed to your VIN for seamless integration. This unit oversees vital systems like lights, locks, wipers, and climate controls, restoring reliability without dealership visits. It’s interchangeable with numbers like 25844480, 25835966, and others, fitting models including Chevrolet Silverado, Tahoe, and Cadillac Escalade variants from 2007-2013. Drawing from two decades of diagnostics, I’ve watched this fix transform frustrating breakdowns into smooth drives, preventing cascading issues like misfires from poor grounding.
Common Issues & How This Fixes Them
One frequent headache in the 2007-2011 GMC Yukon XL 2500 is erratic HVAC behaviorโthink blower motors cutting out mid-trip due to BCM signal loss. This stems from internal module degradation, often exacerbated by moisture or voltage spikes in rugged use. Replacing with the VIN-programmed 20939138 restores consistent control, eliminating intermittent operation and related DTCs like B1001. Another common gripe: non-responsive power windows or door locks, caused by faulty BCM relays failing under daily stress. I’ve diagnosed this in Yukons hauling trailers, where vibrations accelerate wear. This module fixes it by reestablishing precise electronic commands, ensuring locks engage reliably for security. Security system glitches, including false alarms or engine stalling from grounding faults, are also prevalentโespecially in older models with high mileage. The pre-programmed BCM resolves these by optimizing communication, preventing misfires and enhancing anti-theft protocols. Finally, airbag warning lights popping up? That’s often a BCM mismatch triggering codes; our unit clears them outright, boosting safety without extra scans. In real scenarios, like a clientโs Yukon towing through rough terrain, this swap cut diagnostic time and avoided costly tows.

Easy Installation Guide
- Provide your VIN during purchase to ensure precise programmingโcritical for GM vehicles like the Yukon XL 2500.
- Locate the BCM under the steering column or dashboard; disconnect the battery first for safety to avoid electrical shorts.
- Remove the old module by unplugging connectors and unbolting itโtypically a quick 5-minute task with basic tools.
- Install the new 20939138 BCM, reconnect everything, and reconnect the battery; no advanced skills needed.
- Perform post-install checks: If no-start occurs, do a theft relearn by cycling the key from off to run (without starting) 3-4 times, waiting 10 minutes each cycle until the security light clears.
- For persistent airbag lights (DTC B1001), use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure; some may need brake pedal recalibration for optimal safetyโconsult your manual or a pro if unsure.
