I have 195,000 miles I replaced my thermostat, and the blend door seems to be fine. If my heater core gets clogged how can I tell, and would it stop me from having heat?

Your heater core could be air locked. When did you stop having heat? Before you changed the thermostat or after? The heater core is a radiator that is in side your cab. The fan blows threw it and sends the heat through the vents. You can follow the heater core lines into the cab from the engine compartment. Check to see if they are hot or air locked. You can feel the fluid in the lines when is cold too.
