AFAIK, there is only one automatic climate control temperature sensor in the interior. It is in the far right (passenger-side) of the dash, behind the circular grille below the air vent. It is in the opposite position of the headlight switch, in other words. You can either pull out the circular fitting from the vent housing, or remove two Torx screws from the side of the vent housing and wrestle the vent housing off the end of the dash. I've done that and handled the sensor a couple of times. Good luck!
