Hi my name is***** will be glad to try to help. If it is not switching between hot and cold that would be a blend door actuator problem. You will need to check to see if the actuator is working and also if it is actually moving the blend door or is broken from the door. If it is not moving then the circuit will need to be tested for a loss of power to the actuator or a failed actuator.
