Sounds like the heater core is clogged. How is the car running reguarding the temperature. If its running cool then the thermostat is either struck open or has been removed .Are you the original owner? BYM

Check that the heater control valve (if equipped) is opening if this is operating correctly than you need to flush the heater core. Do this by removing both hoses from the heater core and using a garden hose. Continue to flush until you have a good flow.
