1999 Gulfstream Sun Voyager 275 HP ISC Cummins

You were all extremely helpful with my question re my 1999 Gulfstream Sun Voyager 275 HP ISC Cummins. It made the trip from TX to OH with absolutely no trouble. Now another question...I'm getting no heat off the motor when in the travel mode, just cold air out of the heater vents. Any thoughts..blocked heater core???

Been several posts about this problem.. as your getting NO heat (as opposed to little heat), I would follow the heater lines back and see if there are any valves in line that are off..
