Your 1998 F150 has 3 relays for your power door locks : an all unlock relay / a driver unlock relay / and an ALL LOCK RELAY I'm guessing that the ALL LOCK RELAY has failed I'm sorry but I haven't found the location of the power lock/unlock relays on your F150 yet ( does anyone know the location of the power door lock / unlock relays on a 1998 F150 ? )
