Help, I am trying to replace the humidity sensor in my 2012 Chrysler 300. I have watched and read every forum that states it is on the windshield next to the rear view mirror. There is nothing there. I have taken apart the lighting component, looked under the mirror, around the mirror, I have taken the sides of the dash out and nothing.
