    Manual HVAC controls no rear air.

    Now that it's getting colder the temperature of my heat is awful.

    I replaced the temp door actuator when I purchased @171k.

    Recirc door is closed.
    I removed the heater control valve because it wasn't opening or closing when changing the selector, I plan on replacing.

    I have had the heater core back flushed and both hoses get hot, yet still mediocre heat.

    I'm at a loss, there is plenty of air flow but like warm heat. Could the temp door be the culprit even though no cold outside air is getting in?

    What am I missing?
