    First thing I'd check is your coolant level.

    If the coolant is low, it will blow cold air.

    What kind of apu?

    So the bunk heater has stopped heating? Or the heat ducts have stopped blowing heat?

    Normally, a thermo-king has a diesel fired bunk heater.

    It may or may not have an Arctic kit that's tied to the e gone cooling system.

    You haven't given enough information to really understand the system.

    Your initial statement made it seem like an engine issue.

    Now it's an apu issue. And it's unclear how it's installed

    Bunk heater?

    How much fuel do you have?

    Check Fuel Level,but that shall be OK.
    Check for Fuse on Night Heater.
    Check if Fuel comes to Night Heater (Maybe Pump stopped due to Electrical or Mechanical Fault)
    There musst be some kind of Spark Plug. Its not sparking but just to give ya an Idea. Check it.

    Some Trucks switch Auxiliary off when Voltage goes low. Here we have 24V and charging 28V. If Voltage goes under 22V the Auxiliary gets disconnected to keep Truck able to start.
