Make sure both heater core hoses are getting hot. If they don't, flush the heater core. Also, check the blend air door to make sure it is working properly. It is a vent door that allows air to pass over the heater core. If it isn't opening or closing properly, you won't get heat. Finally, make sure the engine is running at a normal operating temp.
