got email response back from service dept.. quote below:
"..the tech checked all the air inlets and ducts, all functions are operating normal, the tech checked another like-same veh that has the same operation- also contacted ford tech hotline, this is a normal operation and ford wrote back that a difference of up to 10 degrees is concidered normal operation. so right now all functions are working as dedigned by the ford engineers.. the focus is ready for pick up"
ok so it sounds to me service depts need more help from Ford with this one... ball back to Ford headquarter court..!
(btw.. from above techs quote "a difference of up to 10 degrees is concidered normal operation" this refers to the temp diff I feel from left vs right vent from central dash... find that very hard to accept as normal...)
