My 2001 Ford Taurus no longer has cabin heat Where do I start looking?

Answer 1

check for anti freeze in the overflow jug on the side first.

if the above does not work check the coolant lines going into the firewall from the engine compartment. Check to see if they are both hot. If they are not you might need to flush out the heater core. There are 2 common causes of 'no-heat' when the coolant is flowing:

# Blocked / plugged heater core

To check - confirm that both heater hoses going into the firewall are warm. If only one is warm, likely there is a blockage and the core will have to be flushed and/or replaced.

# Temperature blend door is stuck in the cold air position

#* The door itself is binding and not able to pivot

#* The blend door actuator has failed - see "Related Links" below for the Autzone.com online repair guide to replacing the blend door actuator / motor. It's only about $15

check how high the temp gauge goes if it doesn't go above 1/3 of the gauge change the thermostat or check the tap unit on the firewall. pull the 2 hoses off the heater core on the fire wall then take a garden hose and flush all the muck out and you will have heat
