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...

X2 on the vacuum leak that Krusty described.
We had a similar thing happen to our Class C last year, except that the A/C was coming out of the defrost all the time. In the Class C the vacuum reservoir is buried and very hard to get to. I wound up buying a new reservoir, check valve some vacuum tubing and fittings and cobbled together a bypass. I never found the original leak location but all is well now.
