NHTSA complaint #11154071, filed 2018-11, 122,000 miles“Driving on humid day, closed windows and turned on A/C. Controller failed to close defroster vents, causing window to quickly fog up, restricting forward vision. Previously had same problem on 2006 Grand Marquis which I had repaired by ford dealer. Took 2011 to dealer, got repair estimate of $900, as dashboard must be removed to get to failing part. Am told problem is vacuum leak in controller component. Although associated with A/C, which generally is not considered a safety issue, the controller failure does result in a safety issue, and in my opinion should be subject to recall.”
