I Have A 2002 F250 Nothing Works On The Overhead Display, Cannot Find A Fuse , Could It Be The Display Itself, If So How Does It Come Out ,Cannot Find Any Screws. thanks

Welcome to FTF. One of the techs will answer shortly.

The overhead console in my ex doesn't work if it is hot outside. It is working since the temp has cooled out.
