Several possibilities, (I am assuming there is air actually blowing, but it is cold), your not getting circulation through the heater core, coolant level is too low. i had the same prob my front defrost would not work what i found is that it was a small plastic tube that runs the side of the motor that is connected to the vacume. those plastic tubes get very brittle and break easy, once i fixed that tube my defrost worked
