everyone is right.....this is the default no vacuum modes for most 928's that only have the 1 center comb flap
1: recric flap is open for fresh air only
2: footwell flap is closed, so no footwell airflow
3: center comb flap is closed (down) so air is diverted more to the side vents from the center
4: defrost vent is open
5: heater valve is open (hot all the time)
changing airflow on the control won't change anything.....all you can do is adjust temp and AC a bit until vacuum is restored....

The cold air coming on intermitently points me to a conclusion that it's not related to vacuum. If it was a vacuum related problem, I would be getting hot air when set to cold. I'm getting cold air when slider is set to hot. The big question is this: does moving the temp slider all the way to max hot overide the outside and inside temp sensors?
Just buy a used one from 928 intl for around $25....I think I posted a thread on it...I'll see if I can find it
