SOURCE: I have 1998 cadillac STS
this problem is caused by a defective air temp control blend door motor, this door and actuator motor is located inside the dash between the heater core and the AC evaporator core, it shifts airflow through the heater core or the AC core or mixes or blends the two for the desired temp at the outlets, the motor will have to be replaced. This is a very common issue.

sounds like it might be low on coolant. Low coolant levels will stop the flow and circulation to the heater core, and also might be the cause of overheating

SOURCE: 99 STS AC is blowing hot air
I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.
I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

The doors that open and close in the heater control unit are ran by motors. It sounds like a motor has quit in yours. When turning on the defrosters the motor closes the door to the heat for the floor
