Expert:  Randall C replied 1 year ago.

I am still confused a little, The compressor is to run in defrost, That is by design so I am not following the question in that it never shuts off

Get heat on heater no heat on defrost

If you have your heater on and no heat is coming from the vents then can you grab both heater hoses and see if they are both equally hot? If they are then you have a blend door actuator or blend door itself is broke...

Blend door is working fine. Heater core is 20-30 degrees different from one side to another and it's brand new

The problems only on defrost mode

Can you tell me if this door is moving?

Heater blows hot. a/c blows cold. Defrost blows as cold as a/c
