Haven't worked on alot of the 98 models, however, check the hoses goin to your heater core. If these are leaking from being loose or cracked it could very well be your problem. also check for seals in your passenger side door. the seal that your door presses against when it closes has a tendacy to come loose and will cause external water sources to enter the vehicle.
