see if both heater hoses are getting hot , if they are that means the hot fluid is passing throw the heater core, then its a blend door problem .if one is hot and other is cool then there is a blockage or some systems have a vacuum switch that cuts off the hot water supply to the heater core while the A/C is on check that. hope this helps.
