Feel all the hoses. Wearever the resriction is will be colder on the other side. If the hose going in to the heater is hot & the one comeing out is cooler the heater core may be stopped up. Also make shure the coolant in the radiator is clear full. If it is a little low it can get poor circulation.If all the heater hoses are hot you could have a heater door not functioning.
