Is my heater core bad or leaking?
1995 Pontiac Grand Am GT
186000 miles
Symptoms:
-Leaking antifreeze. I usually have to top it off every couple months or so, the low coolant light will come on. I put in about half a jug?
-Passenger side floor is consistently soaking wet. I have not smelled it to see if it smells like antifreeze yet tho.
-My inside of my windows frequently get condensation on the inside of them, and now in winter it freezes and makes frost on my windshield especially, which is annoying. If i let my car sit overnight or even for a few hours then I come back to it, there will be condensation inside
There is not antifreeze odor coming from the vents, that I can detect. My car does not overheat. My heat works.
From your knowledge would this be a sign of a bad heater core or a leak in the heater core? Or could I go to an auto shop and have them look at it and they would know? Last but not least, if it is the heater core, how much would a repair cost me roughly?
also, i'm not sure if this has anything to do with it, My A/C doesn't really blow cold.
And also what would you do?

Sounds like your heater core or your heater control valve. If you shut off the heat and you still have leaks, the culprit could be the valve, especially if the flow begins at the valve and then the heater core.
Neither one is easy to fix, though neither is too expensive either. Get a repair manual and read the troubleshooting chapter. Or ask your trusted mechanic. Not particularly difficult, but time-consuming since a lot of the dashboard has to come out to get at the heater core or the heater control valve. Cost depends on your locality and your mechanic's ability to get under the dash. ... Take care!

If you have been losing anti freeze regularly you most likely have a heater core that is rotting at the seams and the leak is going to get slowly worse , leaving the carpet wet for a long time will eventually rot and discolor it I would try Bars leak in the plastic bottle if you want to try to seal the smaller leaks, but if your cooling system is old and tired this may plug it up completely. Its probably best to drop the dashboard and replace the heater core its about 5 to 7 hours depending on the year make and model but this will eliminate some problems you have now and the worse ones that are headed your way when the seam blows out and you car is dead in the middle of the street.

Heater core most likely leaking, would suggest repair ASAP before engine overheats and will ruin carpet. Depending where you live would rough estimate $250.00-$350.00 parts and labor, would also suggest new thermostat and coolant flush at same time. Shop will give you free estimate,
