Climate control system not working properly. I have checked the thermostat and flushed the radiator without success. With heat set to maximum (90°) I get full heat when set to maximum air. Obviously air-conditioning is not working, but that is not my issue. When set to direct heat to the floor, the temperature is cool and the airflow appears to be okay. When I switch back to maximum air I get heat. I can hear the blender actuator doors opening and closing and it properly directs the airflow to the defrost, floor, and air. So the problem seems to be a temperature sensor for the floor and normal heat setting. Any suggestions on what needs to be fixed? I'm reluctant to dive into the actuator as it requires full removal of the dash. Winter is coming that I need help as soon as possible as my feet are freezing.
