First check to make sure coolant level is full. Then make sure both hoses are hot going in and out of your heater when engine is heated up. Then check the actuators on the heater i'll send along a generic view. These control where the air goes and cold/hot. They can be vacuum or electric operated. See if they are getting power or vacuum.
