Turn-Signals and Back-up light Dead....Help!

[garryk6]

OK, I was changing my Tail Lights out to the new 08 style lights. Had the key on, and the truck in Reverse, and accidentally shorted the B/U light wires. Lost Back-up lights and Turn Signals. Checked fuses 17, 18 and 38. All good, checked good. Replaces with new, still same, power at fuse bluck, and fuse good, but no lights. Saw that trailer harnes might be a problem. Unplugged my connector housing from the harnes plug, found water in the plug. Dried it out, but still no lights. Any other ideas?? Is there another fuse, or circuit-breaker or relay that I missed? Brake lights all work and the 4 way flasher works too, but still no B/u or Sig....
Thanks in advance,

Well someone from the Ford Trucks Enthusiasts forum just told me to go check Fuse 27. It is not labeled as B/U or Turn SIg, but it was blown, and when I replaced it, everything works great!! Hope this helps someone else.
