Before you can have heat the engine has to be above the temperature you set. Let’s say it is 10 outside and you left the EX out all night. The engine coolant is 10 degs. You start up the engine remote or by key. You set the temp to 75. The engine has to be above 75 to even start to provide heat. You turn on the inside fan to max it cools the coolant temp from 75 down to below that because of the heat exchanger or heater core. When engine gets above 100 it will start heating the cabin. On my 17 I hit auto and let it run for 10 or 15 minutes on remote start before heading out.
