My heater blows cold, even when I switch the temperature back and forth there is no change. I have checked the coolant and the hoses going to the heater core are both hot. So I wanted to know if it could be one of the actuators and if so which one and where is it located?

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
