Assuming we are talking about the temp blend door actuator, if the air coming out of the heater ducts in the cab is cold and the temperature control is on hot and the engine is running and fully warmed up (195 degrees) and the coolant reservoir is on the full mark and both heater hoses under the hood are hot, you probably have a faulty temp blend door actuator. If you have one heater hose that is hot and the other is only warm or cold, you probably have a plugged heater core. If both heater hoses are only warm or cold you probably have a stuck open thermostat.
