Due to medical issues I do not get to drive my cars as often as I would like. We have had a great deal of snow in the part of the country where I live and I last drove my 2010 E350 several weeks ago before we had some snow storms. Yesterday I needed to use my car and when got into the interior the first thing I noticed was condensation on the inside of the windshield. I have never had this issue before and I would like to know if I should be concerned. Is there anything I can do to rectify this problem.
