I would give the dealer a shot. I have found the best way to do these is to have a tech go for a ride with you, so you can point it out. I have tried detailed instructions, but they never make it to the tech. If you cannot duplicate it, then it will be up to the dealer if they want to take it apart and look, as Ford might not pay them for the work.
If all else fails, it isn't that hard to take apart that area. I have had might apart twice to clean the radio display; the second time I put a clear tablet shield over it.
