sounds like your heater core has gone to seed. generally heater core replacement involves removing the dash and should be done by a mechanic or car nut. the cost of this procedure is dictated by the difficulty (time involved) of the process. you can expect to be set back at least a few hundred bucks.

check the water level of your radiator first. The heater gets it heat from the radiator/ cooling system. The heater intake hose is normally located at the top of the engine, meaning that when the water level is low the heater is the first thing to loose water, which will result in cold air coming from the vents.
