    Have you tried cleaning the contacts on both the lenses and the camera?

    It sounds like the focus screw-drive linkage from your body to your lenses is not working correctly. Try wiggling your lenses rotationally back and forth a bit to see if it is an alignment problem. Once the drive "seats" into the lens you should regain full autofocus capabilities.

    There is also the manual focus switch on the camera that may be in the wrong position or acting up.

    It turned out to be the screw drive. It had become and "innie" instead of an "outie". A simply retraction of the spring loaded screw drive with a jeweler's screwdriver and we're off an running.

    Suggestion: Carry a small paperclip in your bag as a fixit tool. It works as well as a jeweler's screwdriver.

    While I'm glad you found a way to extract the retracted drive, I should remind you that these things rarely improve by themselves. Either the mechanism has become dirty or needs lubrication or (worse case scenario) needs replacement. A trip to Nikon service is probably indicated and recommended.

    And you may find the difference is focus motor is in the lens which is
    why it works. If you're using the 70-200 f/2.8, it's got an internal focus
    motor.
