I've just recently got a 2005 diesel zone 2.8 it has duel zone climate control if I set it at hi heater always blows hot.... That I notice if I drop it to 76 or 78 it blows out quite cool unless I'm sat in traffic then seems to be warm is this normal could it be a huge stupid flower my wife has put on middle blower maybe a sensor or is it just chrysler as on hi it is hot very warm just when drops to 77 or even 80 it's cool unless in traffic
