Ford Edge interior fan and light issues

I have a 2011 Ford Edge SEL Plus. I'm having an electrical or computer
problem which I can't seem to figure out. This may or may not have to do
with the SYNC display, but that is where most things are noticeable, so
that's what I'll be talking about. The interior cabin fan runs sporadically,
turning off and on. The levels of blowing work fine. On the display itself, the
clock and temp blink on and off. The ambient cabin lights blink on and off.  
So basically, the cabin ambient lighting, fans and clock all turn off and on.
Everything else works. The radio and CD play fine. I can bluetooth to my
phones and play music without a problem (at least no more of a problem
than SYNC normally has). My navigation works fine. My air conditioning and
heat both work, though the fan that blows them is the one that turns off and
on. Also my temp within the cabin doesn't work, so I either have to set the
temperature to LOW or HIGH to get any real change in temperature in the
cabin.  I'm not the most mechanically inclined, but hoping it's a simple thing
like changing a fuse or something. More likely I'm thinking it's a bigger
problem, but I have no idea what that would be (motherboard or something
else?) and no idea how to diagnose it. Have others had this problem, as I
can't seem to find it anywhere on Google? Any suggestions will be a big
help.
