Try checking the antifreeze level, make sure the Hose to the Heater core isn't kinked and the cable valve is open. Then I would install a Flush kit and change the Thermostatand antifreeze after flushing.
This is a very big job, You must remove the complete dash assembly, then remove the heater box assembly , then replace the heater core and reassmble everything that was removed to gain access to the heater core.
Replace the engine thermostat, it is probably stuck open.
It is located where the top radiator hose enters the engine block and is supposed to close when the engine is cold, thus prevent coolant from going to the radiator while the engine is heating up.
At engine operating temperature, it opens up, sends the coolant to the rad, and keeps the engine coolant at that constant temperature.
99% of the time, this is the culprit.
The other 1% could be a clogged/partially clogged heater core, or a busted heater core (accompanied by a coolant leak/loss over time) which fogs up the windows even more when the heater is on defrost.
Thermostat replacement is an easy, quick job and cheap.
Heater core replacement is a little bit more time/money consuming
