Running Hot and Fan is Not Coming On

[dismiss@earthlink.net (The Judge)]

Gents: (along the lines of the all the "cooling posts):

I noticed today that my engine temp gauge showed that I was running hot.
The needle was right of center (not all the way), but much more than any
other time.  I noticed that the "control unit" for the cooling fan was on
the same circuit (fuse) for the instrument lights I had a problem with
(which now work).  Anyway, the fuse for the control unit is fine (as are
all of the other fan fuses, and every other fuse), but I noticed that the
fan is not coming on at all.

It usually comes on when I am sitting at idle after awhile (and when I am
driving, obviously), but not now.  Any suggestions?

Please help if you can.
Thanks.
