question about turn signals on 2005 Lincoln Aviator

I have a 2005 lincoln aviator and the turn signals do not work. The hazards are working fine, i was wondering if there are any common problems with this one

There is no frequent problems, but we have seen a few multifunction switches (turn signal switch) failures. A couple of fuses to check F2.21 10amp and F2.5 15 amp.
