Is Your GM Truck or SUV Plagued by Baffling Electrical Problems?
If you’re dealing with flickering lights, a malfunctioning HVAC system, or power windows and locks that have a mind of their own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. This VIN-programmed Body Control Module, compatible with part number 15198116, is the definitive solution to restore full electrical functionality to your 2003-2007 GMC Sierra, Chevrolet Silverado, Tahoe, Yukon, and other compatible GM vehicles.
Common Symptoms of a Failing BCM

- ✔ HVAC controls not working or blower motor operating intermittently.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ Illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ No-start or intermittent starting conditions due to security system communication failure.
- ✔ A variety of communication-related DTCs stored in the vehicle’s computer.
