Well, my fears are at ease. No heat in the cab isn't caused by the thermostat though. Water circulates through the heater core even with the thermostat closed. That means you may have a water valve not open, a bad water pump, a blockage in the heater core, or the water level started out so low that by the time it heated up any, all your coolant had simply become steam, which doesn't tend to pump through heater cores very well.
