My 1999 Grand Prix has no heat. The defroster has heat and the blower is blowing only cold air. Last year the blower didn't work and they replaced the ignition switch. Also in the past year they've replaced the intake manifold gasket, thermostat and water pump after some overheating issues. I was hoping that something was just frozen as it's been under freezing here for days but I went out for a long ride yesterday and that didn't help.

warm the car up and check to seee if the heater hoses are getting hot, if not you may have a flow problem with the heater core. If they are hot, check the blend door under the dash to be sure it is moving from hot to cold.
