2011 A/C issue
 

Having a problem with the A/C in my wife's 2011 Mustang (V6 Base). Air is blowing cold out of the passenger side but warm out of the drivers side when set all the way cold. It will slowly get clightly colder on the drivers side when you drive. Unit is charged correctly. I have replaced the Blend actuator and reset by removing the fuse. Also lifted battery cable to try to reset. NO luck and I am all out of ideas. What else can I check?

Another note is this seemed to suddenly happen. Was working great a few weeks ago.
