Your car should have ECC, so stop trying to 'beat the system'. Put it in 'auto' mode, set the temperature to your desired temp, like 72-76F on both knobs, year-round leave the AC switched on and the recirc off, leave the blower speed in auto, and let it do its thing.

During hot weather, the blower will try to cool the cabin just after engine start. And in cold temps, the blower will start as soon as there is heat in the heater core.

I suspect that one of the vent flaps is not closing completely, due to lack of use. If the vent motor is malfunctioning, the yellow blinking lights will notify you that there is something wrong with the system.

If there is indeed an issue with the temperature dial on the passenger side, the only known fix is to replace the ECC unit.
