Hey folks!

I never adjusted the dual climate control in my car (I live in Florida) and used to have it on the coldest setting all the time, blowing ice cold air out of my a/c. Now, I went on a little road trip with a friend and she was getting cold after a while so I told her to adjust the temperature with the dual climate wheels. Nothing changed however. The only time the temperature changed was when she turned it all the way to "hot" (last red dot) and then hot air blew out of the vents.
Is something wrong with my a/c? Does anybody have a similar problem?
Thanks for letting me know!

Nick
