Where is the Retained Accessory Power Module located at on a 1999 Chevy Suburban?

The Retained Accessory Power (RAP) module location on a 1999 Chevy Suburban isn't standardized like a fuse box. It's integrated into other modules, often the Body Control Module (BCM). There's no single "RAP module" to find.

Therefore, there's no specific physical location to point to. The RAP function itself is controlled by the BCM, and its programming dictates how long accessories stay powered after the ignition is turned off. To work on the RAP function, you would need to access and potentially reprogram the BCM, usually through a scan tool.
