Hey Lee!

Does your van have the air control flaps removed or disengaged?  And how
about the thermostat.  Is it hooked up and functioning correctly?  I also
think that 6 miles in a bus really isn't very far to go and doubt that
it could heat up that big interior in sucha short trip.  It's probably
just getting warm when you get to your destination.
