Starglow Gettin' there
I'm not very familiar with the '98 model, but if you charged the AC system and it worked for a few days but now it doesn't then that means it has a refrigerant leak somewhere in the system. There is a pressure switch that prevents the compressor from running when the refrigerant level drops too low to prevent compressor damage. For the fan issue I'd first check the coolant temp sensor...if it's bad then the computer may have defaulted to a fail-safe fan on position.
