I have this new problem with my 07 expy. Sometimes when I turn the **** to change where the air blows out of, like from panel to def, it won't change. Then if I keep turning the **** eventually something makes a noise under the dash and it move to the correct place, then it will keep working until I let it sit for awhile.
Any ideas, I am not sure if this is still vacuum driven or electronic.

So I have been doing some testing on this and here is what I found out.
If I leave the selector switch in the panel position say overnight and get into my truck in the morning and turn it to defrost of mix it doesn't move to that position right away and eventually the actuator reacts and changes after a few minutes, usually and once it does it works fine the rest of the time.
If I leave the selector switch in the defrost or mixed position overnight and go to select panel it moves right away and will continue to move any time there after.
So it seems like the actuator doesn't like to be left in the panel position overnight or for long periods of time. If this is an electronic actuator it may have a bad spot on the actuator that eventually make contact and tells it to move but if its vacuum then I'll have to see what else I can come up with.

I'm assuming your 07 is no longer under warranty?

Yeah, it is a common problem with most F150's, Expies from way back. In the 06 and older, you had to take the dash apart to get to the door/motor. The blend door motor is a $2 toy motor with a 25 cent plastic gear mounted on it. These gears break and cause the problem. It's a bad design. Some info that may be interesting:
