Replace the heater core. It is leaking.
Recommend you buy a Chilton or Haynes manual for this one. Explaining it without visual references makes it a bit more difficult. Before you go through the process of changing out the heater core, try backflushing it to see if it might simply be clogged.

Since the heater core is heated with hot coolant, it could be that the thermostat is stuck and not opening. You may also see the engine overheating in this case. Or, the heater core itself, which is finned like the radiator, is plugged with particles. Try backflushing the collant system. Lastly, if you need to replace the heater core, it disconnects with 4 screws on the passenger side under the dash. They are relatively inexpensive - approximately $25 USD at this time.
