1999 E-350 - No Air Blowing out of Dash Vents

My RV sat all last year and when I drove it today all the air is blowing out of the defroster vents. Nothing comes out of the dash vents.

I checked a fuse for a modulator door and it was good.

Searching around I see I should look for a vacuum hose off but I do not even know where to look.

I have a 1999 E-350 where half the engine is under the hood and the other half is under the dog house.

I was planning on leaving for an extended trip in two days but I cannot go anywhere without good AC.

Any help much appreciated.

Dennis

That's a vacuum leak. Keep looking for a vacuum hose, check valve, controls, reservoir, etc.
