Could this be 2 separate problems?

it is probably a bad heater core
No you cannot sue unless it was sold with a warrenty.
The water is not circulating through the heater core or you have a control problem. If the heater is putting out heat then it is probably a control problem. If no heat then - water pump out, low on coolant, or maybe the therostat is stuck open.
no
Most likely your heater core is leaking.
heater core may be partly plugged .
The first thing that you need to do is check for a vacuum leak for the a/c and heater system, this is a very common.............
Why the heater or defroster may not work in a 1993 Chevy Caprice Classic because of the heating core is going out.
If the heater works but the defroster doesn't on a 1995 Buick Skylark, it could be due to a malfunctioning blend door actuator, which controls airflow between the heater and defroster vents. Another possibility is a clogged or damaged defroster duct, preventing warm air from reaching the windshield. Additionally, low coolant levels or a faulty thermostat could affect the defroster's performance. Checking these components can help diagnose the issue.
Yes they have a heater/defroster.
Your car's defroster may not be working due to a few common issues. It could be a problem with the blower motor, which may have failed or become blocked. Additionally, a malfunctioning thermostat or low coolant levels can prevent the heater core from warming up the air. Lastly, check for any blown fuses or damaged wiring in the defroster system.
Ok..I figured it out. Turns out the rear defroster is the problem. When I unplugged it from the back windshield, blower/heater works great!! So...to all those out there..if your blower motor blows fuses...check the blower motor first...then the HVAC and heater fuses, then rear defroster if you have a cavalier!
