Q: Has anyone lost their heat in this vehicle and fixed by resetting codes? on 2008 Mercury Grand Marquis

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Here is the process I used that worked for another person on this site but doesn't appear to be working for me:
Press at the SAME TIME, "OFF" & "FLOOR" , then
Press "AUTOMATIC".
The Display will turn a digital circle for awhile until it will stop on it's own to display any Error Codes. In my case it displayed a steadt "024". That means "Door Actuator". In fact while it is diagnosing you can hear it trying to Reset the door by a repetitive clicking sound.
After doing this self-diagnose/Resaet sequence three(3) times, WARM air finally started coming out the heater vent. (It was late night & freezing at the time.)

the blend door actuator is either bad or the blend door is broken. very common on fords. the clicking was it skipping teeth. it should reset with no noise
