One problem related to defogger has been reported for the 2011 Ford F-350. The most recently reported issues are listed below.
My 2011 F-350 truck's heating system suddenly would not switch locations. It was stuck on dashboard heating, and would not switch to the floor or to the defrost. The truck is 2 years old. At the beginning of winter, driving without defrost is rather hazardous as it is difficult to defrost the windshield. I had to pay to get it fixed, and it cost me $1862. 37. I feel that any vehicle's heating system ought to operate without issues for a decade or more, so it was rather frustrating to hear that Ford would not cover it on my 2 year old vehicle. Besides the common sense frustration factor, it could be a safety concern if it is a common occurrence in that people may not be able to defrost the windshield, which could result in excessive frost buildup in northern climates, which can block the driver's vision and result in a crash.
