2007 Ford Freestyle defroster issue

For along time there was clicking when heater/ac turned on. I was told it could be the blend door or actuator for the floor as it has not been working properly. Now the clicking has stopped completely. The main heat vent works but when I turn it off the defroster goes on full speed and will not turn off using the off button. If I push off and then shut off engine and restart car the defrost will stay off until I turn it on again. Any ideas? Blend door, blower motor resistor, blower motor speed control unit? Or possibly more than one issue

Yup any or all. Considering you didn’t fix the original problem, why ask now?
