At work we have a 2005 F150, 5 Speed,6 Cylinder.
My boss was picking up parts about 6 hours away from home and the Turn signals stopped working on the truck.
All together the Brake, Turn Signals, and Hazards just failed.
Fuses checked good. I remember the older F150's had an issue of the wires getting "pulled" in the steering column, Causing the circuit to be open to the Hazard switch which caused all the lights to fail.
Unsure if the newer trucks are having that same issue, Multiple google searches yeild me nothing but relations to the older models.
Thanks!
