Help!!! No Heat!!!

[EASRBS@xxxxxxx]

Hello, coming home from dinner tonight, I was burrowing to my heated seat and
noticed that my heat was not working.  I cranked the heat up to the max
setting (from 72) and the temp did not change.  I did the same with the
passenger side and it warmed a little.  It may get below 32 here some the next
couple of days (Brrrrrrrrr for Georgia) so I would like to fix it tomorrow if
possible.  Can anyone tell me where to start looking or give me an idea of
what the problem may be.  Thanks in advance.
