I checked heater core hoses and they are both hot to the touch. I also checked the operation of the blend door actuator and it is working. I have single zone climate control. Any ideas??

    The Journeys have had some issues with getting plugged up in such a way that only a part of the core retains coolant flow, try backflushing it and if heat isn't restored someone will be pulling the dash to replace it.

    I was afraid of that. Should I just use some water to flush or is there a need to use a chemical also?

    Take 2 hoses off and blow back through the heater core with compressed air..
    Now here the part these tech don't know
    Install the hoses back on backwards and the
    System will back flush itself , I just did it today
    On a ranger and the heat is mints..just keep the hoses on heater core backwards.. That's the 1 thing these car building idiots
    Didn't ruin yet , the heater core can be ran backwards there's no sensors or direction of flow...be careful in pulling those hoses off ,twist really easy or slit with a razor and twist , the heater core pipes are delicates...

    That is a good idea, but am I right in thinking that you want to get most of the crud out of the heater core before doing this?
