My front and rear heat does not work and it will also slowly overheat. I have changed the radiator, the thermostat, the water pump and blew out both heater cores.

Hello my name is Dave.

It sounds like there is a possibility that you have an air pocket in your cooling system. This is especially likely with a dual heater core system such as yours. The symptoms you have described really sounds like low coolant which air pockets could cause. I have attached a link for our tutorial for flushing and filling the cooling system. I would recommend flushing the system as added assurance, however I would strongly recommend following the fill procedure at the end:
