Jeff, I would get that problem with the no heat thing checked as soon as
possible.  If you are getting combustion gases into the coolant your
coolant is being transformed into acid and it will eat the inside of
your coolant system up like a ravenous rat.  You can get a test kit from
NAPA for $45 that will tell you one way or the other if you are getting
combustion gases into the coolant.  It is called Block Test Kit and if
you need more info pmail me.

What does your coolant temp look like on the gauge?  It could be that
your thermostat is bad and isn't let the engine get warm enough to keep
the front heater hot on cold days.  BTDT with my 90 Carat.  I put in a
new 87 deg thermostat (stock) and I have great heat now.  Before the
coolant temp would never get above the white on the gauge.  Now it runs
in the middle like it should.

If you need any more advice or parts please let me know.
