Heater core may be air-bound and need to be bled or heater core may be plugged Remove one water line to heater to see if there is water flow to same. Connect 1st water line and disconnect 2nd to see if there is water flow through heater core
AnswerThe first question that would come to you? 1= are the heater controls operating properly? if they are then 2= is the heaters thermostat operational?
Another possibility might be that your radiator fan is not turning off, this happened to mine (though mine is a 1998) my heater had worked the year before but this year it wasn't... we replaced the thermostat and still nothing, on a warmer winter day we flushed the system to clean it, and nothing, finally my dad noticed my radiator fans seemed to be staying on all the time, he looked it up, pulled the fuse for them out and the heater worked just fine, later we replaced the fuse (didn't even buy a new one) and since then the fans and heater work perfectly normally... kinda random but it worked...
