Hello and welcome. this is caused by a bad temp door actuator for the drivers temp door. you will need to replace the drivers temp door actuator. this is a electric motor that moves the temp door from cold to hot and hot to cold

Could be a head gasket leaking compression into the cooling system. This results in an air pocket at the pump that will not allow the coolant to flow at low coolant system pressures. When you rev the engine up it causes enough flow to give heat to the heater core

check the coolant. then outside under the hood near where the 2 hoses go into the heater core there is a heater coolant control valve. make sure the vac line is connected and not broke. feel the hoses there at the heater core after it warms up. are they hot? if not the valve isnt opening and letting coolant into the core

you have "blend doors" under the dash, most likely you have dual side temp controls, and the little electric blend door actuator is bad, they are not easy to get to, but can be done in the drive way, hope this helps,
