Air is stuck in defrost position and all vacume lines are intact why won't it change to vents.

That's the one. It's pricey from Ford, I think around $250.

My truck is doing the same, vacuum hoses seem to be all good....my truck does this intermittently, as I raise the temperature to bring the fan speed down it will switch over to vents instead of defrost. I'm stumped, but winter is on it's way and I won't have to worry with it for a while lol.

This is why I wanted manual 4X4, a POS vacuum pump can keep you from having it when you need it.

Is the vac pump running? Key on, pull the hose off at the pump and see if it kicks on.

I'd bet you have a leak and the pump ran constantly and ate itself.
