Most electrical power supply circuits in this American crossover are protected by fuses. High-current consumers are routed through relays. These protective components are housed in power distribution boxes located under the hood and within the passenger compartment.
The information provided in these diagrams applies to the 4th-generation Ford Explorer (U-platform / chassis code U251) models for the years 2005, 2006, 2007, 2008, 2009, 2010, and 2011.
Engine Compartment
The power distribution box is located on the right side of the engine compartment, behind a plastic cover.
