I get hot air from my heater when it’s on the lowest fan speed setting. If I turn it on a higher speed, cold air comes out

Maybe you have air in the system which causes poor water flow to the heater core. Other possibilities are a worn water pump or a dirty heater core. A cooling system flush might help.
