So I took my truck in for a full detail today, including the engine bay, and now I have no turn signals or brake lights, though the 3rd brake light still works. Took my multimeter to both fuse boxes and all fuses are good, tested the bulbs and they are good, the running lights all work so no bad wires, even replaced relay #1 in the fuse box under the dash kick panel. Really at a loss here as to what else it could be. I've only had this truck for 5 days, so not at all familiar with it, or Fords in general so any help will be greatly appreciated!
