Thermostat has been changed heater core flushed out antifreeze is full what can it be? Is there a wire or a fuse I should be checking? The blower works just blows cold air.

There is a cable that controls the temperature door. Remove the glove box and the climate control assembly. Verify the cable did not come off the retaining clips.

Hey AMUNN,

This sounds like you have one of two things going on, first you may have a blend door actuator that is not working, next you could just need the climate control reset, Pull the fuse for the climate control for 5 mins to see if that fixes it, if not here is a guide for the blend door actuator.

Please let us know what you find so it will help others.

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