bad water pump or low coolant level
Turn it on high
Probably a bad thermostat.
A bad thermostat can cause overheating in a Nissan Frontier when the air conditioning is turned on. A bad compressor can also cause this.
faulty control valve on heater or air in the lines
blowing cool air, is the air only in your mouth... warm air comes from your lungs. temperature also varies by how open your mouth is while blowing air out

A couple possibilities are: low coolant level or bad water pump. just based on overheating and no heat, sounds like the thermostat is bad or it could be the water pump thermostat
Your compressor is not working. Through evaporation compressors cool the evaporator coil and the fan blows air across it. So if the fan is blowing hot air the compressor is not cooling the coil. But check to see if the dial inside the fridge is turned to "more cold" , that turns the compressor on.
it's an air conditioner because you made it into cool
Check the temperature control cable
