What would cause the heater to blow cold air the hoses going in and out of the heater core are hot fluid level is okay?
I would suspect the thermostat is stuck in the open position so the water ( and motor ) never reach operating temperature. This is common where hard water ( water with a lot of minerals ) is in people's taps. I would suggest replacing the thermostat and draining out the coolant and replacing it with new antifreeze mixed with distilled water.
You could have an inoperative blend air door inside the dash, or the heater core is restricted internally.
What else can I help you with?
