What exactly is the problem? What does it do or not do? I mean does the defroster work? Does the A/C still work? If nothing works then it could be a climate control computer problem. If they work, it could be a plugged heater core.

if its not getting hot and the heater core is take both heater hoses from your motor and flush your heater core with the water hose
