Hey how are you
The actuator is just a slave components ,commanded buy the ac module . It want move by itself
1-you either have a Bad used ac dash unit ( I Recommend rebuilding it, or Replace with a known good one.)
2-Look at the connector of the ac dash unit for any backed out pins not making a good contact , spray electrical contact cleaner on it
3-also get the Mode door actuator and check the electrical connector on it as well .
Let me know if you need anything else on it , just reply back here & we can continue.
if you are good , Please Kindly rate me.
Hope I was helpful to you
