I have a 2010 Ford Fusion SE and the problem I have is.... After I have been on a trip and driving for 4 hours or more,all of a sudden I don't have control of the a/c,heater,defrost...etc. I can hear the blower motor running but I get no air coming out at all. No matter what I do,I can't get them to work unless I stop and turn off the car over night,then the next day it seems fine,everything works again. I've taken it in to the dealer but they can't find what is causing the problem or they just don't know where to look to find out. Can anyone give me an answer to my problem,so I can tell the dealer what to look for...??? Thanks!!
