Typically just spring and fall, outdoor temps in low 50s, typically when no sunshine and raining, so wipers are on. Climate control on auto, set to 71 degrees, but really hot air out of dash vents, sometimes floor vents, whatever was used last perhaps. Leaving on auto, turning down temp control a few degrees at a time, no change. Open climate control center on touch screen, turn down temp all the way to LO, then very cold air comes out. Changing temp up a bit at a time, no change. So, either it will do extreme HI or extreme LO. Turn off the entire system, wait a couple minutes, back on...same trouble. Turn off system again, usually then OK. In heavy rain when very hot air is blowing, also seems that the recirculation door is stuck closed, inside windshield fogs up terribly and fast, dangerously bad visibility. Have to turn on front defogger. This is all tricky to deal with while driving in heavy rain and reduced visibility. Worst news of all is even with repeated stories of this each spring and fall since new car purchase in 2013, dealership service guys say they've never heard of this, can't find any info on this, and no offer for any kind of fix. I read other forum discussions on similar trouble and their dealerships have replaced this that and t'other. I'm soooo frustrated. My dealership basically is saying if they can't replicate it, they can't fix it, not to mention their dismissive tone with me when I suggest what I have read on forums (yup, I'm a woman!). I need a short list of what to replace in what order to take into dealership. I've met with sales manager to complain, just got lip service. I'll soon meet with general manager. Thanks in advance.
