    It could be a faulty temperature control actuator on the driver side or a broken blend door. I’m not sure if your car has several temperature sensors, if it has – it could be a faulty temp sensor. However, the easiest way is to read the trouble codes and try to see if the actuators are moving when selecting temperature.

    Have seen this happen where the the temperature blend door actuator goes bad,  Do you hear any noise when you change the temperature settings?
