I have had 3 Ford trucks....2 Expys and a F 150 ...CC still worked even though bulbs were burnt out on all three
big difference between bulbs being burnt out and not getting power to the light assembly though

Have you owned this truck since new?
Your Expiditions and other F150's wouldn't count (unless they're 04-08 F150s).
Just search google for "cruise control third brake light" and you will see many, many posts about how cruise is inop if the TBL burns out or if you try to add an led without a resistor.
However, all of that is besides the point. First test to see if a new bulb works. If not, it's obviously another issue.
