Check your coolant level and make sure its full, next i would look into replacing your thermostat, if your thermostat is stuck open your engine isnt able to reach operating temperature therefore heater output suffers, your coolant temp gauge should read around halfway when the engine is hot if its not look into replacing the thermostat, if your gauge is reading halfway check the cable going to your heater box when you adjust your temperature on your heater controls its possible that the cable broke or the blend door inside the heater box is stuck into the cold position allowing only cold air to come through the vents.
