Q: clogged heating core: on 2000 Ford Taurus

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My car has no heat but the airconditioner works great. I have no leaks within my coolant system nor does the heater core leak, I have been told y morre than 2 repair shops that my heater core might be clogged. How do i unclog it? One repairman told me to us a hanger to unclog it, PLEASE HELP!
I am truly sceptical that your heater core is plugged. Especially when someone tells you to use a coat hanger. Yikes. First of all, when the vehicle is fully warmed up and the heater has been turned on for a while, carefully grab the heater hoses and compare the temperature of both. They should be about the same temperature I suspect. If they are relatively the same temperature, then the problem is under your dash with the air distribution system. A blend door or actuator may ot be routing the air properly. This is the most probable cause I believe.
Thanks for your response; can the blend door be fixed or do I still have to replace the entire heater core?
I had the same trouble and it was the blend door actuator. On the 2000 Taurus the blend door determines the amount of cold/hot air delivered to the cabin.
