I've dealt with precisely what you describe. Make sure the aux air flap
is functional. Then check (or just replace) all the related vacuum
lines (those that disappear into the firewall, for example). There's
also at least one check valve in the system that prevents boost and
vacuum from working at cross purposes.
Not that this is very helpful, but you don't need to turn the AC off-
just back off the throttle to get out of the boost and you'll see the
flow directed correctly. Not much good when climbing a long hill . . .
Or you could just buy my car that needs a head :-) A/C has repaired
vacuum plumbing, along with new compressor, evaporator, controller and
everything else related.

Subject: Climate Control Issues.....
I seem to remember a recent post regarding climate control issues
regarding center air vent problems. Please forgive me, but I can't
seem to find the thread, nor do I remember a solution to my current
problem being posted.
I just got my A/C recharged, and when idling or cruising with little
throttle, no problems, just a faceful of nice cold air. Hit the
throttle, and the air goes from the center vents to the defrost, icing
up the windshield after a little while. Turn it off/on again, center
vents working, hit the throttle and back to the defrost vents. Any
Again, please forgive me if this was recently posted.
