From what you describe it would appear that your vehicle may be having an issue with the heater. It may be possible that one of the heating and cooling system components has failed.
If the heater switch, or the heater control valve fail or have an issue, they can allow hot coolant into the heater core, which will be felt in the cabin. This issue may or may not be related to your AC issues, as the systems are separate, but intertwined.
