I can’t get my temperature to change. I have changed the actuator and it still stays on one temperature.

Hi,
If the blend air door actuator is moving the door, then I suspect the heater core is clogged. Try this and let me know the results.
Start the vehicle when it's cold. Turn the engine on the heater on and allow it to reach operating temperature.
Turn the heater off, Feel both heater core hoses at the firewall. Both should be hot. If they are, the issue is inside with a temperature door. If one is hot and the other is not, chances are the heater core is plugged.
Let me know,
Joe
