first you should check the coolant level when the engine is cold... if it is low you should get some coolant and fill it ..and check for leaks ...if full then you could have a bad thermostat or possible a plugged radiator and or a plugged heater core...the way the heater cores are designed they would partially plug up and you would loose heat on the drivers side but have heat on the pass side...good luck
