Vacuum problems A/c
OK 1994 F-350 with 351 A/C works great. Problem is when on max A/C air comes out dash vents great, nice and cold. But when motor gets in to a low vacuum below 7" the dash air is gone and blows out at my feet. It"s still cold
but not coming out the dash.As soon as I lift off the throttle the air will come back out the dash vents. It"s takes a minuet or so. I think its a vacuum problem but where to start, I need a vacuum diagram for the A/C system.
