Called Bryan Thompson he also believes this is a programer problem. So the plan is now to remove the programmer, control head and put them in a box with my actuators to Bryan.

I wish the blend door had been fluttering before I removed the heater box, might have saved some work.
I'd be interested in the part# on the label of the programmer when you remove it. I believe I've one stuffed away somewhere but it's difficult to put a 'hands-on' currently.
