Being that it's a '98, it shouldn't have side airbags, right? Off the top of my head, remove the trim piece by the mirror by pulling out on the top. Remove the courtesy lamp on the bottom of the door panel with a suitable screw driver. Then remove the outer shell of the inner door handle. Screw driver would work, but you may scratch the leather in doing so. You'll have to pry on it with something. There will be two screws under it. If you do have side airbags, which you don't, remove the SRS badge with a screwdriver and remove the screw under it. Then find a place you can slip your fingers behind on the door panel and pull it off. Start with the bottom to make it easier. Then lift the panel up off the upper window seal. Disconnect all necessaries, and whala.
