Check if the blend door is working, do you hear any operation or change when temperature setting is changed? If not, possible blend door problem. Or do it is that you have heat at the floor and not on your face, it could be a mode door problem. If neitherr, then check thermostat? Hold hoses to and from, should be firm. Heater core itself can be plugged on these models. You can check the temperature of the inlet and outlet hoses at the firewall with an infared temperature gun. They should be equal. If drastic difference, core is plugged. Backflush the heater core if this is the issue. If improves and returns, new heater core will be required.
