Hey guys, With AC on starting to climb a hill at like 60 in OD, as I increase throttle pressure the air comming out the front vents just switches to the defrost vents at the windsheild by itself and switches back when I let off; happens regularly but only when your foot is in it a bit; not enough to make it come out of OD. I was thinking it was the valve that controlls all the stuff down there but I'm not sure where to start. Sounds like a vacuum leak or something. Ideas anyone?

Thanks, Mike.
