Sounds like the heater core maybe? does it smell like coolant or any coolant loss? AC actually de humidities air

If not a heater core problem(most likely) then its a humidity issue. Here in Southwest Florida, my truck and car both sometimes fog the inside windshield till the AC pulls the moisture out of the cabin. Use recirc AC mode to pull out the moisture. Got to love that 90% humidity.....

Also clean off the windshield really good, that will help from fogging up on the inside. There's some kinda film that forms and it will fog up easier than a clean window.
