First, do you smell anti-freeze in the cabin??? If not, it may not be your heater core. Condensation maybe coming from your evaporator drain hose . The hose is easily replaced by accessing the port under the car and pulling on it gently. I replaced mine with a rigid clear hardware store type hose and preheating the end of it prior to fitting into the evaporator box.If you have to replace the heater core, it is in with the evaporator -in the SAME box. Therefore, 22 hr charge via dealership. If you decide to do this, PLEASE replace the evap because they have to dissconnect the darn thing anyway. If this is an original evap/heatercore, you need to replace both. PLUS-- all the vacuum actuators as well. Sorry... I did this project 14 months ago and it was a major PITA.
I was qouted 3200 big ones to do ONLY the evaporator. Considering the age of your car, if you do one , you should do the other- unless you enjoy being up side down for hrs. taking small bolts off the bolster. Good luck
