Could be the thermostat, heater core, heater control valve and the air blend door/actuator.

Check your coolant level first. That is the number one cause of no heat.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
