First thing you should do is have the climate control module scanned for fault codes and remedy those codes. You may want to also check to see if there is a softeware update for the climate control module and update the software and carry out a recalibration of all the damper motors. You may need to take it in to Volvo for this if you can not find a shop with the proper equipement to carry out this check.

Hapy new year.
Thanks for that, that problem has been solved and it's the same that u indicated. The problem was investigated during the scanning(third one)
and only recalibration for dampers have been done.
Thks again for that.& Hopes that mine volvo would be more frendly)and do not bring up such as gifts before holidays.
