The first-generation Ford Expedition (UN93) was built on the Ford U platform, which it shared with the Lincoln Navigator. It was intended to replace the outdated two-door Ford Bronco. This article provides detailed fuse box diagrams for the first-generation Ford Expedition (F-150 derived body-on-frame platform; chassis code UN93), covering the 1996, 1997, 1998, 1999, 2000, 2001, and 2002 model years.
Below are the locations and photographs of the power distribution boxes. The fuses protecting the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
Engine Compartment
Up to three fuse boxes are located in the engine compartment, depending on the vehicle's trim and configuration. The primary fuse block is available in two different versions.
