there is a delicate balance between evaporator and condensor...if the drain is blocked and the moisture cannot exit the condensor "cask" will pool up...have some one "PIN" blast the exit tube~...frosted condensor would indicate lack of charge (or is it too much charge)...well if it was charged recently....let some out of the shroeder valve~
Check the tables to see what the charge should be for your evaporator/condenser setup there...there are tables for this~
Air door is most likely stuck or has something blocking the air flow through the dash unit. Check and see if your climate system is electronic or cable operated. If electronic then it likely that a servo motor for A/C is inoperative. If cable then look for the cable to have dislodged itself from it's holder or broken off.
