How do you fix your power door locks on a 1998 ford explorer?

Start by checking the 25 amp fuse in location # 18 of your fuse panel (located on the driver's end of the dash - visible with the driver's door open.) This fuse is for the driver's door unlock relay, all unlock relay, and all lock relay. I'm not sure if the relays are located in the jack storage compartment like my 1995 XLT, but if nothing works it's most likely the fuse.
