Hi All,
So for the longest time I have been without heat.
I did the basic checks and all was well.
Figured out how to see both passenger and driver actuators... both were unplugged.
Plugged them in, did a blend door reset, have heat again.
Up until this point I havent had any issues with the AC.

Wife messages me this morning and says the blower suddenly went to the 3rd bar and temp setting dropped to 62. She tapped the buttons to increase the speed but it didnt respond. She turned it off, but then could't get it to come back on.

Clearly the actuators were unplugged by the previous owner, and somehow knew the AC would function without them being plugged in. So, what is it that could cause the AC controller to mess up with the actuators plugged in vs not?
