Thanks It does explain the symptoms Seems most likely a leaking vacuum
pod.will check it , mostly behind the centre panel
mak
My guess is that one of the pods has a vacuum leak, and when the
ACC goes to actuate it the vacuum leaks away and the system defaults
to the defrost vent pattern.
Hi all need to know if the compressor control unit next to the fuel relay
controls just the compressor ?.
As the dialled temp of 20 C approaches the centre vents air all gets
diverted to the screen. Should it not go the side vents and then come back
as the temp deviates?

and the
climate control goes to defrost all the time.

Hi .the model is a 1990 300SE.
The airflow does comes out of the centre vents , then as the dialled in
temp approaches, currently at 20C, the airflow diverts completely to the
windscreen.
The air flow comes back to centre vents if the temp is reduced further say
18'C

PLEASE,
