Dash AC blows out of the defrost vents
the dash AC blows out of the defrost vents when engine is under a strain, such as climbing up a hill, etc. my motor home is a 2000 itasca suncruiser. the engine is a ford v10 i feel it is a vacuum...

Cant speak to that specific model, but many vehicles in the last 20 years have had computer systems aboard that when certain conditions exist, causing any problems with vacuum or heat control systems, the computer defaults to only service the Defroster with any climate control air.
My Buick did this when the evap coils had a hole poked in it.
That it returns to normal likely shows it to be a control item designed into the system.
