    I have no heat coming from the dash or bunk in my 05' 387, the AC works and the blower works, when I turn the dial to heat nothing. There is no smell of coolant or signs of leaks, header tank is full on truck.

    Grab the heater hoses at the cab and bunk cores to be sure they are hot to the touch at operating temp. If cold, check that the engine is at operating temp of 180*F. If cold and engine at temp, check for shutoff valves being closed at the engine.

    If hot to the touch you have a control issue with the doors. Most common is failed actuators or water/ corrosion in the electrical connectors. You can swap the actuators as they are the same. Temp and recirc actuators are outside under the hood at the top, pull the case back , they are on the top under plastic covers.

    To close this topic out, it was indeed the water valves turned OFF. Warmth is good.

    Thanks,
