Pinpointing the OBD2 Fuse Location
For your 2000 Lincoln Navigator, the fuse responsible for the OBD2 (On-Board Diagnostics II) port is located in the passenger compartment fuse panel.
Specifically, look for Fuse #3, labeled “Cigar Lighter, OBD-II Scan Tool Connector.” This fuse is a 20A MINI fuse. If your OBD2 scanner is not powering on or communicating with your vehicle’s computer, checking and replacing this fuse should be one of your first steps.
It’s always a good practice to consult your 2000 Lincoln Navigator owner’s manual for the most accurate fuse box diagrams and fuse assignments. Fuse box layouts can sometimes have minor variations. However, this guide provides a strong starting point for locating the OBD2 fuse and understanding the fuse system in your 2000 Lincoln Navigator. Remember to always replace a blown fuse with one of the same amperage to avoid further electrical problems.
