2014 express upgraded to 8.4 from 3.0. today i noticed airflow doesn't change unless i switch off climate and then sometimes it doesnt change even when i turn it off and on. most of the time it only flows through floor vents. also temp controls are screwed up the same way. when i change them they dont change unless i shut off climate. would this be unit problem?? harness? or climate module??

thanks in advance
