high pressure blast with a "pinner" needle blast...you may have one in your toolbox, but they've been outlawed for the consumer....so go to your local shop, tell them you need a blast of air out the exit tube, if they are mechanics they will find it immediately...you may want to change the environmental filter too, while you're over there~

Do as the judge suggested but if it has been plugged for a period of time then you may have a mold build up inside the A/C case, they make a spray that kills the mold build up inside the system, it is sprayed througg the air intake of the A/C system, most shops can do this for you or you can buy the stuff at a parts store and do it yourself.

your A/C charge may be low, a differential between condensor and evaporator is a delicate balance, if you have insufficient charge may cause condensation and dripping~
