In this article we take a look at the third generation Ford Explorer (U152), produced from 2003 to 2005. Here you will find the Ford Explorer 2003, 2004 and 2005 fuse box outline, get information on the location of the fuse boxes inside the car and learn about the assignment of each fuse (fuse layout) and relay.
The fuses for the cigar lighter (socket) are fuse №24 (cigar lighter) in the instrument panel fuse box and fuses №7 (socket #2), №9 (socket #1) in the engine compartment fuse box.
Fuse box location
Passenger compartment
The fuse panel is located below the instrument panel on the driver’s side.
Passenger compartment fuse panel (top side)
