Thermostat working, blender door working, don't see a heater control valve on this truck. 2001 f150.

Sorry. Meant heat is ONLY blowing cold. Saving heater core as last resort. Going to check everything else first but thanks for the response.

Heater cores are a pain to replace but you may be able to flush the system and heater core and she will blow hot again
