The control head is where the board is. No heat? Is your heater core stopped up, or thermostat stuck open?

Is the coolant level topped off?
Thanks guys! Am being told that the board is the reason I cannot get the heat flapper doors to move. Water lines are hot both ways on front and rear system. Rear system has same trouble with a seperate set of controls. Am a bit flustered!
