Always blows cold air, seems to change from setting(defrost, ect.) But air conditioner cycles, and the air is cold, pulled relay for pump, now the air is outside temp. But still cold. Changed the controlls in dash but made no differance

Check for vacuum leaks to vent door actuators under dash, and with the engine hot, running, the heater on, feel both heater core hoses. Are both hot? If so, check blend air door. If only one is hot, flush heater core.
