The Body Control Module (BCM) in a 2000 Chevy Silverado is typically located
under the dashboard, on the driver's side. However, the exact location can vary slightly depending on the specific trim level and options. It's often behind a panel that requires removal to access it.
To find it precisely, you'll likely need a repair manual specific to your year and model Silverado. A search online for "2000 Chevy Silverado BCM location" along with your specific trim level (e.g., 1500, 2500, etc.) should yield diagrams and further information.
