On my 99 it's under the dash, right by the blower motor, not sure if 98's the same. Most manufacturers put them by the blower motor and use the air from the motor to cool the resistor. It will have a couple of wires going to it and will probably be held in with 1 or 2 7mm or 5.5mm screws. The resistor on my 99 has 7 wires going to it. Hope this helps.
