Coolant Leaking out of A/C Drain? HELP!

I have a 2000 f250 7.3 and it has started leaking coolant out of the A/c drain/condenser drain, thats located on the firewall on the passenger side. I took off my fenderskirt to verify this and I can watch the coolant come out of it. When I turn on the air condition or heater air also blows out of the drain pipe. I also see water squeezing out of the seams of the plastic box (dont know the name) under the dash on the passenger side. My questions are

1) Is this being caused by a bad Heater core or just it being clogged?
2) Is the A/c drain just clogged?
3) Is it normal for air to blow out of the drain?

I stuck a long screwdriver in the drain and it came out clean.
Thanks ahead for any help.

are you sure its coolant? color, smell? Air is normal to come out of the drain hole when clear. The hole is an ac evaporator drain, its normal to plug up with dust after a while. clearing it is a good idea. Are you losing coolant? Smell sweet when you turn on the heater blower?

If it is the heater core its an easy job. Hardest part is the datgum clip on hoses going into the core.

Its definitely coolant. Its green and smells like coolant. Ill try tomorrow to clean it out I guess with compressed air. If that doesnt work Ill try flushing the heater core and then if that doesnt work then replace the heater core. Is there a better heater core out there for our trucks then the factory types?
