Question on air conditioning XC 90

I also have the problems with the cold secondary air and the bad working climate automation. I could burst if I only think of the comments of my contract workshop and VCG. Now on the topic: When the automatic climate control is activated, the air comes almost exclusively from the smaller defroster nozzles, not from the adjustable nozzles for the interior. Is this so wanted and technically correct? (When the automatic is deactivated, nice warm air comes out of the nozzles in sufficient quantity.) parkbank
