Possible clogged heater core, air in the system, clogged radiator, I would flush the system with a good radiator flush a few time, bleed all the air and see what happens
Check to make sure the thermostat is working and reaching operating temperature. If temperature is ok, check to make sure you're getting coolant flow through the heater core. If everything checks out good, check the climate control switch
