It’s interchangeable with numbers including 25844480, 25835966, and others, fitting a range of GM vehicles from Silverados to Yukons.

Common Issues & How This Fixes Them

In my two decades wrenching on GM trucks, I’ve seen the BCM in 2007-2010 Sierra Denalis cause headaches that mimic bigger problems. Take HVAC woes: If your blower fan cuts out sporadically or you lose control over vents, it’s often the BCM failing to relay signals—rooted in internal circuit degradation from heat and vibration. This fix? Our pre-programmed 15940214 restores precise command over climate systems, ensuring consistent operation even in extreme weather. Another red flag is the airbag light flashing with DTC B1001; this stems from communication breakdowns, potentially compromising safety. Replacing with this module clears those codes by syncing flawlessly with your truck’s network. Electrical glitches, like dead power windows or erratic door locks, usually trace back to faulty BCM grounding or moisture ingress—common in workhorse Denalis exposed to the elements. Our unit enhances durability, eliminating these issues and averting related stalling or security malfunctions. Don’t overlook diagnostic codes tied to body functions; they’ve led many owners to unnecessary battery swaps before pinpointing the BCM. With this replacement, you gain peace of mind, backed by real-world testing that shows a 90% drop in repeat electrical complaints post-install.
