1983 944 Fan Not Working / Overheating

My '83 944 was running very hot today.  Even though the weather was
warm, it is unusual for her to get this hot.  When I got home and
popped the hood I noticed that neither of the fans were running.  The
a/c unit needs a charge so I'm not sure if the one fan will ever come
on.

In any event, are the fan relays known to go bad?  Is there some
simple check I can do to test the relay?  Can / Should  I jump a few
contacts to verify that the fan works?  Any other thoughts?

Cheers!
