Is your 2008-2012 Buick Enclave suffering from bizarre electrical problems? Issues like flickering lights, malfunctioning power windows, or a dead instrument cluster often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated symptoms. This replacement Body Control Module, part number 15921353, is the definitive solution to restore your vehicle’s full functionality.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement that requires a trip to the dealership for expensive programming, this BCM arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This ensures a seamless installation process, getting you back on the road quickly and affordably.
We had a 2011 GMC Acadia (which uses the same BCM) come into the shop with the strangest set of problems. The customer reported that their radio would turn on by itself, the driver’s side power window worked intermittently, and the security light would stay on, sometimes preventing the car from starting. After checking all the basics, we hooked up the scan tool and found multiple communication errors pointing towards the BCM. Instead of a costly dealer visit, we installed a VIN-programmed module just like this one. The installation was straightforward, and after a quick brake pedal position relearn, every single electrical gremlin was gone. The customer was thrilled to have their vehicle back to normal without the dealership price tag.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and door locks
- ✔ Interior or exterior lights flickering, staying on, or not working at all
- ✔ Malfunctioning instrument panel gauges or warning lights
- ✔ Key fob not being recognized or intermittent remote start issues
- ✔ Vehicle security system engaging randomly, causing a no-start condition
- ✔ Unpredictable behavior from the radio or climate control system
Your Plug-and-Play Solution: The 2008-2012 Enclave BCM
This module is a direct-fit replacement for a wide range of original part numbers, including 15921353, 22860591, 25892622, and many more. By providing us with your VIN during checkout, you guarantee that the module you receive is configured for the specific options and systems in your Enclave. While the unit is designed for plug-and-play installation, please be aware of potential post-install procedures.

These procedures require a professional diagnostic tool to complete and are only needed if specific warning lights appear after installation. There is no core charge, so you can keep your original module.
