Heater blowing cold air

I have a 1997 Plymouth Breeze 77,000mi. never really had any problems til today. After starting vehicle I noticed a clanging hear and there out of nowhere. It lasted a few minuites. Then I noticed blower was blowing cold air. I shut it off because windows started to frost up. I turned it back on and noticed heat for a few seconds then it started to blow cold air. Is thiis going to be a major problem? Heater core? If so is this difficult to fix.
Thanks in advance to any advice.

It may blow cold due to being low on coolant. Check the coolant level, does the heat come back when the engine rpm's increase?
Also, it could be a mode door actuator of some sort under the dash, which is not allowing the door to open for heat from the heater core; I'm not too familiar with MOPAR's HVAC setup.
If it were the heater core plugged, I don't think that heat would be felt when you restarted the car.
