Check to see if your car is getting to operating temperature, if driving and the engine is cooling down then it would be a thermostat. Another would be a plugged heater core, radiator flush may be in order, Then there is the out-side air blend door that controls inside cabin temperature may not be working properly due to a vent system actuator module.
