Blows cold air only

Have the damper motors re-calibrated. If it does not work then the temperature mode motor will need replacing and re-calibrated.

Am working on it now. One hose cold to heater one hose hot. I am at temperature.

Car was owned by mom dealer maintenance done until 80,00 miles only had it six months.

Which hose is hot? Is it the upper or lower heater hose? If it is the inlet hose (lower) then the heater core is most likely plugged.

anyway to fix that short of replacing it?

If I turn fan off and wait a couple minutes I get hot air for like a minute then it is just moderately warm.

Bottom hot, top coldish.

Blend door motor sounds like it is working AC line cold and frosty.
Top hose coldIsh.
bottom burning hot.
Top hose has bypass to fill jug and is also hot.
Air bubbles?
Blend door?
I have never really messed with HVAC on car except to replace this newer this thing has has so many wires etc.
Thanks in advance.

And defrost blow cold like ice no heat at all, more like AC.

Disconnect the heater hoses and try flushing out the heater core?

Thanks.
