I had the sensor changed and the problem was solved.
I appreciate your reply. I have been searching for the details of those sensors. Do you have any part number or realoem diagram that they are on perchance?

edit: Looks like I am looking for the "heater core temperature sensor" which seems to be located behind the heater control panel. Does this sound like the sensor you ended up replacing?
