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.

This is EXACTLY what happened to mine this past Sunday(Easter).

The dealer ended up replacing the climate control module its now fixed.

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 not sure if it is electric or vaccum. When I picked up the vehicle from the dealer that Friday, I didn't notice the issue till Sunday so I took it back to the dealer the next day. I did some testing but nothing overnight like you did. They determined it was the climate control module and it was replaced.. since then its been working as it should.

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

It is not under warranty anymore but I don't seem to think it is the module because this is not the automatic climate control just the manual control. I think its the actuator that moves it to each of the selected positions.

Oh well I'll keep at it.

Could be the blend door motor, as these go out frequently. Listen closely for a clicking noise under the dash when your try to change vents.

It makes a clicking noise when it changes so it may be that. Thanks for the help

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:
