MERCURY SABLE HEATER PROBLEM

1998 Mercury Sable • 200,000 miles

No heat. I have backflushed several times. The actuator door is working. It seems as the hoses from the heater core all the way back to the motor are all cool. Temperature hand reads fine.

Check both hoses at heater core if both hot its broken blend door (since you already check blend motor and working )
If one hot and other cool or cold need to isolate heater core and flush again or remove and replace heater core
