If I place my key in the ignition 1 of about 20 times it will not fully insert, yet it is in enough to unlock the wheel and start the engine (6.0 Diesel), but none of the electrical system A/C, Radio etc. works. I then turn it off, take the key out, turn the key over, insert it again, this time fully, re-start and the electrical system works fine. Is this a case of Yugo Flu?
Try another key see it does the same thing. Had that problem on another Ford and turned out to be the key, somehow.
